Book Review: Economic Justice in an Unfair World

The book ‘Economic Justice in an Unfair world:Toward A Level Playing Field is written by ‘Ethan B. Kapstein’. This book focuses on the issue of what is meant by a fair global economy and how fundamental it is in this era. An unfair economy deprives the minorities or financially challenged of the basic rights of their life. The book is written in a market oriented manner which highlights the basic elements of an appropriate international economy as being inclusive, participatory, and welfare-enhancing for all states. The international economy should be structured so as it provides benefits to all economies of the world.Kapstein negates the radical redistribution schemes between rich and poor which cause the global economy to be unjust. He emphasizes, through his book on the point that a politically feasible approach to international economic justice could bring about the benefits of free trade and limited flows of foreign assistance so as to allow countries to earn more and make more profits. Kapstein not only focuses on the elements of a just international economy in his book but also writes about certain fundamental factors that contribute towards a just global economy such as: -Justice in labor -Migration-Investment The book is written for all those people who have concerns for the arguments and issues related to the reduction of poverty and global development. This book provides a detailed illustration of the international community, so as to locate the factors that should be considered in order to structure a global economy that emphasized the benefits of all nations. This book is a must read for people who would want to know about the basic questions relating to the moral economic philosophy. Kapstein makes the use of reasoned writing style in order to present his views to the reader.Through the contents of his book Kapstein attempts to challenge the West's claim which states that the developing countries' should aim at their own develop ment efforts which should be focused on reducing poverty, and this aim should be achieved not through industrialization and economic growth but by the formulation of policies that are directed on the issue of poverty (Ethan B. Kapstein 2006). According to Kapstein, the fundamental element of an international compact is a ‘free-trade regime’ that provides a level playing field.The next factor on which Kapstein focuses in regard to the just international economy is ‘aid’. Kapstein emphasizes through the book on the concept that aid should be used and directed only towards the reduction of poverty but much importance should also be given on empowering the earning capacity of poor countries so that they can take active part on a level playing field. This objective can be achieved through the major shift from the present allocation priorities such as -Primary education -Basic health care -Favor of investment in ports, railways, and the customs and patents bureau cracies.The third point Kapstein discusses in the book is that since migration and remittance payments will become even more essential for developing countries in the future, it is important to create an umbrella regime so as to include issues related to migration, this would help in bringing stability and justice to policies that are now determined by each state. The fourth and last point discussed in the book is related to the issue of international investment most importantly foreign direct investment (FDI). He emphasizes that it should be included in the umbrella regime (Wade, 2006).Strengths and Weaknesses of the Book as compared to other similar readings The same point that is emphasized by Kapstein through his book ‘a just global economy cannot be achieved with only focusing on the factor of poverty reduction, but importance should also be given to the economic settings of nations’, is also debated over in ‘ The No-Nonsense Guide to International Developmen t’ by Maggie Black. Through this article Maggie Black also emphasized that: -The facts that seem to wrong on paper look as wrong technologically or wasteful may have good characteristics on other terms like promoting local leadership, or vice versa-The main aid=development=poverty reduction does not help to understand the meaning and implication of what aid is or how it works (Black, 2002). The main strength of the book is that Kapstein has identified that focusing on poverty reduction will not be enough to justify the global economy by providing convincing arguments with references and quotes from established sources. The same issue has been brought into the light through ‘What I Learned at the World Economic Crisis’ written by Joseph Slightiz.He traces the failures of IMF’s out dated policies to asses and support, the economic conditions of developing countries through his article. Through this he claims that a large flow of power has occurred to the peo ple who have brought the market to the far corners of the globe. These people were economists, bureaucrats, and officials who acted in the name of the United States and the other advanced industrial countries but they were not able to communicate as effectively as they spoke a language that few citizens could comprehend and that few policymakers bother to translate.Economic policy is the most fundamental part of the communication between America and the rest of the world. But it is a grave fact that the nature of the justice of international economy is not just or democratic where big parties such as IMF do not take country constraints into consideration while formulating policies (Stiglitz, 2000). A part of the book by Kapstein is focused on tracing some of the detail issues which are linked to the issue of a just global economy, as they are critical to a couple billion people around the world.Even if some modifications are made in how the WTO works, it would have a negative impact as on the lives of rural peoples, particularly in developing countries. Through the book Kapstein has debated over the topic that merely emphasizing on the issue of poverty is inadequate to make the global economy just as it does not put relations between states front and center. â€Å"It is governments,† he writes, â€Å"that sign treaties and agreements, impose sanctions and boycotts, and make war and peace, and it is governments that — for good or for bad — are ultimately accountable for their actions at home and abroad.† It can be simply said that a theory devised to justify the global economy must stress on the relations between states and the kinds of economic arrangements states subscribe to. Individuals are not the only moral agents but the states are also moral agents, who are responsible to one another as well as to their citizens (Rosenthal, 2006). Bibliography Black, Maggie, 2002.

John Downe

John Downe In John Downe’s letter to his wife, he strategically establishes and develops ethos as well as pathos to convince her to join him in the United States with their children. Throughout the letter, Downe develops his credibility through his use of ethos which includes the repetition of â€Å"I. † â€Å"I have got a situation,† â€Å"I dined with him,† â€Å"I went into the market yesterday,† all progress towards the establishment of his plausibility in his wife’s eyes. He provides his wife with examples of the many positive situations he, himself has endured while being in the country of America.Downe hopes that his persuading words will convince her to emigrate with their children to America. â€Å"I know you will like America† is Downe’s primary hope and purpose for writing this persuasive letter. By describing all the things that he has been able to do in this country, â€Å"I can go into a store, and have as much br andy as I like to drink for three half-pence and all other spirits are in proportion,† Downe hopes that these credential words will be approved by his wife.His elaborations on the things he has managed to do in America are essentially used to provoke his wife’s interest in this country. These descriptions are used as reassurance for his wife to know of the great opportunities he has found in America but not back home in England. Downe believes this will strike his wife as another reason why she will enjoy her new life in America and compares their troublesome life in England to the great possibilities that can be accomplished in this new country.He explains, â€Å"this is a country where a man can stand as a man, and where he can enjoy the fruits of his own exertions, with rational liberty to its fullest extent†, hoping that his comparisons to the life in England and the life in America will evoke in his wife a sense of longing for this kind of living. Downe†™s convincing words showing all of the achievements he has experienced in America lead his wife to want this same kind of exposure.Downe continues to expand on the things he has accomplished in America with his development of pathos through long, periodic sentences. He mentions that on the table there was â€Å"pudding, pyes, and fruit of all kind that was in season†¦Ã¢â‚¬  and â€Å"they do not think of locking the doors in this country† to assure his wife of the safety and prosperity of this country. He then goes on to acknowledge, with emotional appeal, that all he â€Å"wants now is to see you, and the dear children here, and then I shall be happy, and not before†.This is Downe’s development of pathos for the purpose of persuading and influencing his wife to make her decision much easier about emigrating to America with the children. He hopes to influence her decision by explaining how much better off they would be as a family, together in one count ry. Although he announces that he will only be happy if his family comes to America to live with him, Downe concludes that he does not â€Å"repent of coming† and he â€Å"would rather cross the Atlantic ten times than hear my children cry†.By his mentioning that he does not regret one bit coming to America, Downe hopes to display for his wife how great of a country America is. The pathos are purposefully placed there by Downe to show to his wife that although he has left his family, he would do it all over again just to live in the convenient country of America- hoping this will stir some kind of desire in his wife’s mind.Through his emotional words, Downe demonstrates that the travel to America is nothing compared to what this country holds in store for their family. Although he explains to his wife there will be â€Å"a few inconveniences in crossing the Atlantic†, in the end she will enjoy the United States of America. In the midst of his pathos, it i s possible to conclude that Downe’s reason for leaving his family behind is to find opportunity for a new life, which America provides.Through his use of repetition and periodic sentences, John Downe develops credibility and emotional appeal. Through his repetition of â€Å"I†, he is able to bestow upon his wife a feeling of longing for the same freedom and prosperity he has gained when coming to America by showing her all of the things he has accomplished while living in this country. With Downe’s strategic pathos, he manages to convince his wife that all he wants for their family is wealth, health, and land- all of which can be found in America.

Structural Functionalist Theory

This essay is an attempt to discuss the problems political parties in Zambia are facing by using structural-functionalist and their contributions to liberal democracy. The academic piece shall begin by defining the key terms; those being, structural-functionalist, political parties and liberal democracy. This will be followed by a comprehensive discussion of political parties, focused on, with examples, the Zambian scene. Lastly, a brief conclusion based on the discussion will be outlined.â€Å"Functionalism holds that society is a complex system whose various parts work together to produce stability and solidarity† (Giddens 2006:20). It also views society in terms of their functions. Merton (1968), made an important distinctions between manifest and latent functions. The manifest functions of an institution are open, stated, conscious functions. They involve intended, recognized consequences of an aspect of the society such as the university’s role in classifying acade mic competence and excellence.By contrast, latent functions as unconscious or unintended functions and may reflect hidden purposes of an institution. Structural-functionalist acknowledges that not all parts of the society contribute to its stability all the time. This function refers to an element or process in society that may actually disrupt as social system or lead to a decrease in stability† (Schaefer, 2004: 14). Social life depends on unity and cooperation of a group.The functionalist points out that for society to be stable the different parts of the society must contribute to the stability of society. For instance, the teachers should teach the society to reduce illiteracy, the doctors are making sure that society is healthy, and the police maintain order. Hence society becomes stable since everyone is contributing. According to MacIver (1962), a political party is an association organized in support of some principles or policy which constitutional means it endeavors to make the determinant of government.Not only that, a political party consists of a group of citizens, more or less organized, who act as a political unit and who by the use of their voting power, aim to control the government and carry out their general policies. Similarly, a political party is different from a pressure group, though in some cases the distinction between the two is almost blurred. According to Ball (1976), It may be said that a political party is an organization of numerous people who are openly committed to broad matters of public policy and who want to assume direct responsibility  for their policies by seeking monopolize power or share it with other parties in a position of political power.According to Barker (1951), the panorama of a party system is so fluid that a good number of pressure groups behave like political parties. The cases of fragmentation and polarization of political parties may also be taken note of. It is also possible that some minor politi cal organizations emerge at the time of elections and then they disappear. But the most essential fact remains that three, four even more parties manage to share power.For instance, in Zambia before voting is taken place, there are many parties heard like Movement for Multiparty Development (MMD), United Party for National Development (UPND), Patriot Front (PF) and Heritage Party (HP). But at the end of elections only few will be available to be strong holding oppositions party for example the UPND and MMD. Political parties act as a check against the tendency of absolutism and totalitarianism, ideologies also known by names such as ‘Caesarism’ and ‘Bonapartism’ (CITE). When one party forms government or few form coalition to hold power, other parties play a role of opposition.It not only keeps the government vigilant, it also prevents it from being arbitrary and irresponsible. The leaders of the opposition expose acts of corruption, nepotism, scandals and maladministration in which great men in power are involved. According to Lasswell (1950), the political parties enable the power to hold the government in check. The constant presence of a recognized opposition is an obstacle to despotism, with a programmed fairly within the limits of a possible public opinion, is a bulwark against the tyranny, not only of a despot but also a practical political majority.Significant political developments have occurred in Zambia since the 2001 tripartite elections. After having had two previous elections in 1991 and 1996, the 2001 elections produced a multiparty Parliament for the first time since Zambia’s independence in 1964. These elections seem to signal that the country has moved from a dominant one party political system to a competitive multi-party system According to The Post Newspaper (20/01/2013), opposition parties have serious financial difficulties.And for the new member of the opposition, MMD, this is even worse. The MMD doesn't know how to operate without a lot of money. They were used to receiving a lot of money from all sorts of characters doing business with government. And the MMD was also parasitic on government institutions for resources. As a result of this, a series of other problems have appeared. Passions about the future of their party rightly fired people up, but wrongly led them to attack and despise their colleagues. The impact of disunity upon members of the party is clear to see.They must in the very near future learn again to display the camaraderie and common purpose that are fundamental to a party's prospects. If they don't do so, they stand no chance of being re-elected Also, according to Okar (2005), the ruling parties deliberately employ a â€Å"divide-and rule† tactic to fragment and weaken the opposition parties. Wilson (1956) says, â€Å"The numbers of parties that appeared with the opening to democratization is not a demonstration of increased participation, but rather of fragmentation and therefore weakness of the party systems†.Zambia had more than five political parties, and the dominant party was the movement for multi party democracy (MMD), which ruled the country since 1991 to 2011. According to The Post Newspaper (20/01/2013), opposition political parties like, UPND, that was bound together by regional, cultural and language ties is also now failing to conceal its problems and challenges. The regional, tribal and cultural glue that held them together is also starting to weaken. The hopes that they had of getting into government by 2011 have disappeared. The illusions that they had about their popularity have also dried up.And they can no longer deny the fact that they are a regional political party that has serious problems and challenges becoming national. Their arrogance and pomposity can no longer carry them. The bragging of being this and that has proved unsustainable because it is unrealistic. They can no longer claim to be the mos t educated, the most knowledgeable when it comes to business and economic matters, the leading entrepreneurs. Parliamentary statistics actually show that UPND has the least educated members of parliament of the three major political parties.And their leader, Hakainde Hichilema, who tried to project himself as a leading entrepreneur, an outstanding economist and a very rich man can no longer lay much claim to these credentials. According to Mwansa,(2012), The leadership of opposition parties suffer from overly rated ambition for power and pride, such that it overcrowds their effective participation on important national matters that affect the citizenry and poor people. They could be more effective by engaging government and the ruling party in debating policy frameworks on how to develop the country.Particularly,  pushing policies that address the needs of poor people such as improving access to clean water and sanitation, quality healthcare, education, rural and agricultural deve lopment, and debate macroeconomic policy frameworks required for growth and development, critically contributing to poverty eradication, employment creation and addressing inequalities. According to Soko, (2013), the opposition parties have to find their own political shoes rather than to follow in Sata's shoes if they are to earn confidence of the electorates on social and developmental programmers’.The strategies the opposition want to use today, of protesting against the Chief Justice, the demand to have a medical board to examine president Sata's health, the demand to have the constitution changed, among others were Sata's strategies when he was in the opposition. The opposition just seem to be recycling Sata's political strategies with the hope of gaining confidence and trust from the Zambians but this will not work for them as they are being viewed as imitators instead of being initiators.Opposition parties are also not given a fair chance by media. Media is always crit icizing them and portraying opposition parties in a horrible way. All favor is upon the ruling party which is not supposed to be the case. Lastly, one of the very crucial problems in Africa at present is the unwillingness of the incumbent parties to be opposition parties due to their over-dependence on the benefits available to the ruling parties. Therefore, they are ill-equipped to become the opposition.In conclusion, the ruling party in Zambia should try by all means to incorporate the opposition parties in some development decisions, there also has to be inter-party dialogue over how to move beyond the dominant party situation. Because the ruling party feel comfortable once in power and do not want to give chance to the opposition parties to rule the nation. Media should also be an independent source of information and not favor any party but be like a no man’s land that is not owned by anyone, the opposition parties should be able to broadcast their manifestos to the publ ic.

The Translation of Photographic Images Into Painting Essay

The Translation of Photographic Images Into Painting - Essay Example The essay "The Translation of Photographic Images Into Painting" discusses what actually changed the set views and paradigms of artist of coming centuries was the ability to think out of the box. Such artists have given art a new dimension every time. Artists create art to communicate ideas, thoughts and feelings. They use a variety of methods such as painting, sculpting or illustration and an assortment of materials including oils, watercolours, acrylics, pastels, pencils. Artists, works may be realistic or abstract and may depict objects, people, nature or events. We are swamped by so many images, on the streets, in magazines and on the television. Artists usually create landscape paintings in one of four ways: They paint entirely on location; they rely on memory or imagination; they work from photos; or they use a combination of these source. Working from photos to create art pieces as paintings has always been an act which came under darkness due to overlapping views (and counter views too) about ethics of the profession and such other reasons. Some can say that painting taking initial source as a photograph lacks the freshness of thought and the as-it-is natural conditions. Too much reliance on photographs can result in paintings that lack breadth and are broken apart by tedious detail. But using a photograph as a mere source of reference to an idea is not discouraged at all. Rather it is very much beneficial in cases where there is no possibility of carrying painting equipment. or where there is short time between events that change the condition of the idea which has to be captured. Thus we look into the lives of various artists of mainly the twentieth century who have contributed their paintings with criticisms rolling off their backs and the praises not lowering their further elevation of imaginative journeys. "I remember the first place I went to on this trip where we were active, one of the resettlements that we built. I found that as far as I was concerned, they were impossible to photograph. Neat little rows of houses. This wasn't my idea of something fun to photograph at all. But I had the good luck to ask someone, "Where are you all from Where did they bring you from" And when he told me, I went on to a place called Scott's Run, and there it began. From there I went all through Kentucky, West Virginia, down to Arkansas, Mississippi, and Louisiana-in other words, I covered the mine country and the cotton country. I was terribly excited about it, and did no painting at all in that time. This was it, I thought. I'm sort of a single track guy, anyway. When I'm off on photography, photography is it, and I thought this would be the career for the rest of my life."1 The deep interpretative question in Richter's art concerns less the fact that he worked with photographs than why he selected the photographs he did for Atlas, and what governed his decision to translate certain of them into paintings. There are, for example, photographs of American airplanes-Mustang Squadrons, Bombers and Phantom Interceptor planes in ghostly gray-in-gray formations. Richter was an adolescent in 1945, and lived with his family within earshot of Dresden at the time of the massive fire bombings of that year. The photograph from which Bombers was made had to have been taken as a documentary image by some official Air Force photographer, whether over Dresden or some other city. The cool of that

For this assignment, you are to find an on epidemiology in the news - Article Example The researchers studied relations between fast-food /health food eating, and the neighborhood of fast food/healthy food lovers. The participants were more than 5000 middle-aged people from the United States who were asked about the frequency of fast food consumption, the place of its consumption (in the street or in the restaurant) and the place of living. The results of the interrogations were worked out with the aim to determine the connection between active/ not active fast-food consumption and the neighborhood of the fast-food/healthy food lovers. This was compared with the frequency of people’s fast-food consumption near their own homes (Moore, Latetia V.,  Diez Roux,  Ana V., Nettleton Jennifer A., Jacobs, David R. Franco, Manuel, 2009). The results showed that those people who did not consume fast food at all, went on diet very often. In the places, where people like to consume fast-food near their home, the percent of fast food consumption is higher and the cases of going on diet is very seldom (Moore, Latetia V.,  Diez Roux,  Ana V., Nettleton Jennifer A., Jacobs, David R. Franco, Manuel, 2009). Moore, Latetia V.,  Diez Roux,  Ana V., Nettleton Jennifer A., Jacobs, David R. Franco, Manuel. Fast-Food Consumption, Diet Quality, and Neighborhood Exposure to Fast Food.

A critical study of credit risk management in the First Bank of Dissertation

A critical study of credit risk management in the First Bank of Nigeria PLC - Dissertation Example First one is reaction against bank losses from the Newton, it is realized that losses are unbearable after the losses have occurred. The second aspect is that that bank has been pushed by the recent progress in the area of financing securitization, commercial paper and competition with other non-banks to find possible loan borrowers. Big and stable companies have been seen to shift in the open market sources like those in bond markets of finance.The degree of risk of assumed losses can be minimized by organizing and managing the lending criteria with professionalism and also with active approach. Credit risk management issues can be measured if bank could tap progressively refined measuring technique.The adoption of more rigorous credit risk has been facilitated by the technological developments, predominantly the growing availability of low cost computing power and communication. A lot of banks still have a long way to go in the implementation of such new approaches.Competition in t he provision of financial services is increasing probable due to the acceleration of change in credit risk management in the banks which is viewed as an unavoidable response to an environment and, thus need to classify new and gainful business prospects and appropriately measure the related risk is mounting for the banks and other financial institutions. ... When banks extend their credit considering that borrowers will pay back their loan amounts then the extended credit to the borrowers may be at the risk of default, banks income decreases due to the necessity for the provision for the loans as some borrowers usually default. Commercial banks are exposed to an additional risk of variability as they do not have a clue of what proportion of loan borrowers will default. As a matter of fact almost all the financial institutions bear a certain degree of risk when these institutions lend to consumers and to the businesses, hence when certain borrowers fail to repay the loan amount, they experience some loan losses. Credit risk face by a bank has a possibility of loss arising in case of non-repayment of interest or principal or both. Payment delays and the credit risk among procedures can be transferred by the banks and other financial intermediaries (Demirguc-kunt and Huzinga, 2000). Certain techniques are developed for the measurement of th e credit risk which can be linked with pace of evolution (Laker, 2007; McDonough, 1998; Couhy, 2005; Brown, 2004). Different banks are differentiated with their adoption of different credit risk management policies. A bank having assets that constitutes of loans in their portfolio are relatively illiquid and exhibits the highest credit risk (Koch and MacDonald, 2000). According to the asymmetric information, good borrowers and bad borrowers are might be impossible to distinguish, which can result into an adverse selection and moral hazards problems (Auronen, 2003). Due to the adverse selection and moral hazards banks are led to substantial accumulation of non-performing accounts.

Compare Newton and Goethe's theory described in a particular video Essay

Compare Newton and Goethe's theory described in a particular video - Essay Example When the cone is illuminated by white light on either sides, a grey shadow appears on either sides. When a green filter is used to cover one of the light sources, the set up displays a magenta shade. The magenta shade is a visionary creation of the eyes as green’s complimentary color. Goethe spent 40 years formulating his theory of colors. His studies took color as part of the human vision into account. Therefore, Goethe studied the human eye in detail and based his theory on man as an observer. The eye will always strive to bring about unity and totality in the way we perceive colors. The eyes create harmony by initiating complementary colors. For example, Red is the complementary color for cyan. Goethe studied the quality and characteristics of colors and the conditions under which specific colors came into existence. In his theory, Goethe reiterates that light and darkness are co-factors in the formation of colors. He encoded his research on colors on a color-wheel. The complimentary and harmonic color pairs are placed on opposite sides of the wheel. The harmonic colors form a basis for the interaction between a seeing man and the world of colors, that is, when the world shows us a particular color, our vision responds by perceiving a complementary color. The theory is insistent on the fact that the perception of color must take into account the qualities of color in dark conditions and in light as well. In his experiments, Newton constructed a triangular prism to advance his theory of the refraction of light. In the experiment, he directs a beam of sunlight to pass through the prism upon which refraction occurs. The refraction results into a spectrum which is a series of seven colors commonly associated with the rainbow. From the observations he made during the illustration, Newton concluded that the seven colors are components of white light. Therefore, Newton’s theory associates the perception

Solving the Israel-Palestine Conflict Dissertation

Solving the Israel-Palestine Conflict - Dissertation Example Muslims back the Palestinian people, while the Western –Christian countries back the Zionist country. Both the movements have demanded full legitimacy in the Holy land based on divine promises and historical rights that have been derived from the Bible. According to Maoz (2013), Israeli does not consider Palestine a legitimate nation with any link to Ertza Israel, but considers them as part of the greater Arab region. The paper in National Charter of 1964 as Maoz illustrates explains that Palestine is the homeland of Palestinians and are connected to the Zionist state through historical, material, and religious ties. The Jews according to this paper have no legitimate right over the land. A few Palestinian nationalists such as the Nashibis portrayed close ties with the Jewish state, and even had proposed a harmonious Jewish-Arab cooperation and coexistence in the Holy land. However, they were named traitors and assassinated by fellow Palestinians (Maoz, 2013). Similarly, the I srael Council for Israel -Palestine Peace (ICIPP), an Israel group had accepted and acknowledged the need to have a Palestinian state along the West bank in the late 1980s and early 1990s. However, similar conservative ideologies from the Zionist state thwarted such efforts (Maoz, 2013). ... Narratives according to Daoudi and Barrakat have the potential to indicate and perpetuate conflict, but can also lead to a harmonious understanding, leading to a permanent solution to the conflict. The problem in the two narrates is that both the Palestinians and the Israelites have much respect to the static narratives passed to them over generations; critiquing such narratives on their ancestry and rights especially to the Holy land is a taboo. However, as Daoudi and Barakat (2013) observe, the respect in which such narratives are held makes it impossible to question about; â€Å"what is not being narrated.† For example, though the Palestinians and Israelites have narratives that portray Jerusalem as their Holy city, no narrative pauses the question of â€Å"what is his tradition,† â€Å"his narrative,† â€Å"his culture,† and other questions that could make it possible for the other side to think over and above self-narrative, to the meaning and implica tion of the other party’s narrative (Daoudi and Barakat, 2013). The collective memory linked to such narratives on Jewish and Palestinian rights regarding the Holy land becomes an obstacle to coexistence and reconciliation; each party believe their own narrative without taking time to look beyond such narratives. Therefore, the strong conservative ideologies behind ancestry of the two different nations are the impediments towards finding a lasting solution to conflict in the West Bank and Gaza. Gorny (201090 explored the issue of understanding the â€Å"other† in formulating a solution to the current conflict between Palestinians and the Zionist state, and concluded that limitations in understanding the â€Å"other† and the strong religious conservative ideologies from the Palestinians

Compare Death of a Salesman by Arthur Miller and The Metamorphosis by Essay

Compare Death of a Salesman by Arthur Miller and The Metamorphosis by Frank Kafka - Essay Example This occurs as they both spend their lives dedicated to their work and then come to understand their isolation. However, while Gregor’s family manages to find a means of surviving without him, Willy’s family seems headed for disaster by the end of the play. In both stories, the main character remains disconnected with his loved ones because he must work and travel to support them. Willy Loman in Death of a Salesman spends his life traveling from town to town selling and ranking his importance in life to the number of people he knows. However, this gives him little satisfaction and no sense of connection to his family. â€Å"Work a lifetime to pay off a house. You finally own it, and there’s nobody to live in it† (Miller, 1949). This statement reveals the emptiness Willy has found in his effort to provide his family with a home of their own as his sons prepare to leave again. As Linda tries to soothe him, he reminds her â€Å"some people accomplish something† (Miller, 1949). In the same way, it can be argued that Gregor’s transformation in Metamorphosis is a literal indication of his feelings of separation from humanity, including from the members of his own family. Even in his own home, he has taken up the h abit of locking his bedroom doors â€Å"as if in a hotel† (16) and he continues to follow the rules and regulations set forth by his father even though he is the sole breadwinner of the family. In both stories, the main character’s isolation is brought forward as a result of this occupational need. As Willy travels through his territory, he evidently makes numerous friends, as he boasts to his boys in the play’s many flashbacks. However, at the present time in the play, none of these friends seem available and even his family has retreated from him to the point that his wife must remind their son, â€Å"He’s the dearest man in the world to me, and I won’t have anyone making

Community Immersion Essay Example for Free

Community Immersion Essay It is the city base for Jeff Davis Parish which combined has 6 cities in the parish (U. S. Census Bureau, 2010). Jennings is considered a rural area with a population of 10,909 people residing in the city. According to the census bureau the city of Jennings is populated with Caucasians at 7,736, African Americans 3, 076, Asian 32 and Hispanics 101 (U. S. Census Bureau, 2010). Jennings has two sub communities the south side of town where most of the blacks are under the poverty line and some middle class residents. Downtown is where the whites and a few blacks live, these two sides a separated by a railroad track. The founding of Jennings was a manifestation of the dynamic spirit in Americans which led them to continually seek new frontiers and new areas of economic exploitation. The story of its growth parallels that of many other Louisiana towns, but in two respects it has a claim to distinctiveness: its middle western origin and its connection with Louisiana’s oldest oil field. Jennings McComb, for whom the town was named, was a contractor of the Southern Pacific Railroad. He built the Jennings depot on a divide peculiar to southwest Louisiana (Riser, 1948). It is known that he was president of the Louisiana Western Railroad Company and had been associated with Charles Morgan in certain railroad transactions. McComb accumulated a great fortune, not from the railroad transactions. McComb accumulated a great fortune, not from the railroad but from the acquisition of the patent for the arrow tie buckle used in the baling of cotton. In 1901 an Jennings businessmen brought in oil operators to develop the Jennings Oil Field. This marked the first production of oil in the state of Louisiana. Oil became an important element in the economy of Jennings, but rice, the basis of the town’s economy, was still cultivated. After 1906 oil production declined and the importance of the industry to Jennings decreased. Rice remained, as it always had been, the leading economic activity of the area (Riser, 1948). The one thing about this community is the buildings; they still resemble the old design from in the beginning. This community on one side of the tracks maybe crumbling, but Jennings is a growing city. Jennings can give the illusion of nothing is going on and deep down inside of the town is array of discrimination of race, social class, an economic status. II. Community Structure: Community Function Jennings has few clubs for socializing and due to the divide in the population by race. Socialization between the white and blacks are limited if they do not work together. There are normally around event times in the community two different parades one downtown for the white the other Southside for the blacks. The city is ran by the mayor elected, making all the decisions in the city. During events for the city the decision in regards to can it happen is left to the chief of police. The city has two law enforcement agency the city police which handles everything inside the city and the sheriff’s department which is for surrounding parish cities. Each area or parts of Jennings have police jurors that are elected for the area. Residents are to contact their police jurors with complaints; they are then brought before a town meeting that is held each month at city hall. The meetings are open to all residents in the parish; however they are not openly advertised. There are many community leaders, or shall I say power families. These are the people who basically can have anything they want in Jennings. These families have been living here from the beginning and own most of all the businesses in Jennings. Jennings with these power families there is a lot of corruption within the city. According to an interview conducted with a resident of Jennings, it is a visible corruption. They stated that it’s in the police department and in the court houses. The court house is located in central Jennings and shares a uilding with the parish sheriff’s department. The courthouse has two courtrooms and on judge. One Monday’s, Tuesday’s and Wednesday’s are court days in Jennings. Because this is the parish base surrounding cities in the parish have to attend court in Jennings. The mayor’s office is located across from the courthouse, basically if he is in office the office residents have the opportunity to speak with h im. Election for public office are held every two years, however the judge and chief of police have held the same positions for the last 4 years. They were reelected with majority of the vote. Observing and interviewing residents across the tracks with a low economic status on the government of Jennings. Residents of this community fear the police and the government of Jennings. Most of the residents don’t vote because they believe it does not work. On resident showed me the curfew signs located for two blocks in front of the only club in Jennings. Residents reported having to leave the city to socialize (Jennings Daily News, 2005). III. Community Characteristics Jennings is a booming city new school, shopping centers, restaurants, car lots and new additions to the hospital. This is all downtown Jennings, continue to drive to Southside Jennings and the economy changes. The economy in Jennings is low compared to other cities in Louisiana. Local business owner, own most of the shopping places. The other centers are chain stores and restaurants which provide employment in city. To obtain a good job some resident must leave the city and drive at least 30 miles to the nearest city for work. There are 3 public schools and 2 catholic schools in Jennings there is a technical school which provides training in different fields. Just recently I was informed that Southside had the only elementary school residents. According to the Jennings daily news the school was moved uptown Jennings. There are no schools located in the Southside community of Jennings (Jennings Daily News, 2005). Looking for resources in Jennings is like looking for a needle in a hay stack. There are limited resources in the area for residents living in poverty. There is no office of community services which provides applications and face to face case managers for additional household help; the nearest office is 45 minutes away. There is a health unit that provides parenting classes other services to needed residents. Caring Hands is the only resource of helping people pay bills if needed. They help with light bills, gas bills, and water bills if qualified. There is no transportation system in the city, residents with no cars must walk to the stores. The community even with the lack of services seems not to harm most of the community. It’s for the most part beginning to overcome the racism that has been a factor over the years. However it still a big issue here in Jennings. Jennings have develop over the years an array of issues that need to be addressed like the lack of community services, the sub community of Southside Jennings, lack of activities for children, and jobs. With all this going on the murders of eight young ladies since 2005 has divided and turned the downtown residents against the city police that the city police no longer operate alone in the city the Louisiana state police has taken over (Jennings Daily News, 2005). Its apparent when driving through and speaking with residents, the blacks in the community experience oppression from the local government as well as themselves. There is a large amount of discrimination not only with the government but the local police. Residents state even if they are not doing anything the good suffers for the bad. Police patrol Southside and allow no room for socialization. The park on the Southside is always empty most children rather stay in the house. The local police abuse their power an residents live in fear every day. Jennings, Louisiana do not have a homeless population, most residents that lose their homes move in with relatives. Make some home occupied with multiply families. In this community, it’s a plus along with all the other problems they do not need a homeless problem. IV. Summary and Conclusion Jennings, Louisiana a booming city, with hidden racial problems. Jennings with the majority of the population being white runs the local government, making all the decisions for the city. The lack of resources makes it impossible for some residents to access them. It’s a city that can be two different cities in one. Although education is accessible most of the black don’t attend. Jobs are limited less and there is no public transportation out of city to find jobs. Most residents live under the poverty line for the ones who do not are enjoying this community as long as the blacks stay on their side of the tracks. Reading Netting and observing this community there is a lot going on like Social Darwinism due to the blacks believing that income between not only rich and poor, but white and black is natural (Kettner, McMurty, Netting, 1998). The manifest destiny in which is going on in Jennings today.

Definition Of Outdoor Recreation Physical Education Essay

Definition Of Outdoor Recreation Physical Education Essay The term Recreation, which came from the word Recreate means to create a new. Outdoor recreationist defined recreations as recreating something new in people which they have lost while getting so indulged in their work. But the question arises, to re-create what? Therefore, what has been lost during the non leisure time that needs to be recreated during the leisure time? In line with that, Kelly, (1996) states that Recreation stems from the Latin recreatio, which refers to restoration or recovery. The term implies the re-creation of energy or the restoration of ability to function. Recreation contains the concept of restoration of wholeness of mind, spirit, and body. It presupposes some other activity that depletes, tires, or deteriorates that wholeness(p. 25). In other words, people need to move from their working environment and do some kind of activities which can fill that wholeness whining them. Hence, this can only be achieved through outdoor recreation activities. Outdoor recreation, is any leisure time activity which is being conducted outdoor where individuals engages themselves either physically or mentally from a range of choices of activities for their personal satisfaction and enjoyment. This wide range of activities can be subdivided into two categories which are namely, resource based and user-oriented recreation. The resource based recreation is known to be conducted in the natural surrounding that cannot be easily duplicated by man and on the contrary, user-oriented recreation can be provided anywhere such as theme parks. Types of outdoor activity There are a wide variety of outdoor activities which can be categorized into land based activity or water based activity. Some of the well known activities are listed below; Bicycling Camping Canoeing/Kayaking Boating Fishing Freshwater Swimming Hiking Horseback Riding Hunting Motorized OHV Riding Nature Study Picnicking Beach Activities Visiting Archeological and Historic Sites Canoeing/Kayaking Canoeing/kayaking refers to the use of one or more single or dual blades, paddles, to propel a canoe or kayak forward with only human muscle power. For planning purposes canoeing/kayaking also represents many different forms of paddling activities, such as rafting or whitewater rafting. A majority of the use is facilitated through canoe/kayak launches and designated paddling trails, although such facilities are not absolutely required. Boating Freshwater and saltwater boating is the leisure activity of traveling by boat, or the recreational use of a boat focused on travel itself. Boats vary greatly, from powerboats to sailboats or humanà ¢Ã¢â€š ¬Ã‚ powered vessels. Although there are many different forms of boating, their basic similarly is the requirement of a water body as their principal supporting resource. To provide access to a body of water, boat ramp facilities and marina facilities are commonly developed by outdoor recreation providers. Swimming Freshwater swimming is an outdoor recreation type embracing all of the various activities carried on in fresh water in which the participant is the sole means of locomotion. Specialized variations of swimming include diving, skin diving, and SCUBA diving. Resources and facilities commonly found at outdoor recreation areas that provide freshwater swimming include beach areas, docks and swimming and diving platforms. Benefits Framework Outdoor and adventure activities benefits have been analysed and portrayed by using a variety of models/framework in the past. As presented in the work of Stiehl and Parker (2007), these model and framework have been summarized in table 1-4. Table 1 Benefits of Outdoor Adventure (Darst Armstrong, 1980) Dimension Benefit Personal New experience adds a kick to participantsà ¢Ã¢â€š ¬Ã… ¸ lives, allows them to experience something High-risk experience facing perceived danger may help participants overcome fears, gain self-confidence, and enhance their ability to cope Escape offers release form the tensions and complexities of modern life Success allows participants to achieve a highly personal senses of accomplishment Knowledge participants learn more about themselves and the environment Physical fitness physical activity can help burn calories and increase strength, stamina, and flexibility Economic Minimal financial investment provides interesting and pleasant activities at a reasonable cost Social-psychological Socializing provides a chance to meet others who have similar interests Unity promotes cohesiveness and doing things together without the distractions of everyday life Cooperation and trust promotes better relationships through cooperation, appreciation of others, compassion and respect Nature and outdoors promotes aesthetics appreciation for nature and concern for vanishing wild places Table 2 Benefits of Outdoor Adventure (Ewert, 1989) Dimension Benefit Psychological Benefits on a personal (versus group) basis: Self concept (enhanced or strengthened view), self-efficacy (self-confidence), self-actualisation (well-being, improved self-expression, feelings of psychological health) Sociological Compassion, cooperation, respect for others, communication Educational Improved academic abilities, awareness of nature and the environment, problem solving, outdoor skills, values clarification Physical Strength, co-ordination, balance, cardiovascular endurance Table 3 Goals and Benefits of Outdoor Adventure (Webb, 1999) Dimension Benefit Recreational Enjoyment, relaxation, entertainment, excitement, catharsis, self-expression Skill Goal setting, decision making, problem solving, responsibility, physical development, nature awareness, communication, leadership Character Independence, interdependence, self-efficacy, willingness to take risks, tolerance, respect, trust, compassion Table 4 Benefits of Camping (American Camp Association, 2005) Dimension Benefit Positive identity To the participant: e.g. self-esteem, determination, dependability, ambition, independence Social skills Beyond the individual: group bonding, cooperation, conflict resolution, appreciation of differences, leadership, community, connected to others Physical and thinking skills Activity skills, technical skills; physiological benefits of physical activity Thinking skills: knowledge of safety measures, planning, problem solving, environmental awareness Positive values and spirituality Acquiring and strengthening virtue; selflessness, compassion, keeping commitments, fulfilling obligations, self-discipline, honesty à ¢Ã¢â€š ¬Ã‚ ¦ Connection to earth, others and even a higher power Health benefits of outdoor recreation Generally, outdoor recreation is known to improve people`s health and this can be achieved by doing regular physical activities. Similarly outdoor recreation contribution to health is often considered in the context of Wellness. According to the World Health Organisation (2003), health is defined as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. This definition shifts from a strict medical model of health to a simple concept of well-being. Hence, the Alberta Centre for Well Being (1989) found that the concept of well-being or optimal health involves a delicate balance among physical, emotional, spiritual, intellectual and social health. In the same way, outdoor recreation covers all those aspects of health and also helps in not only enhancing the physical health but also the emotional well being of humans. During a research and promotional campaign, Carney (2001) confirmed the fact that physically inactive people have greater risk of having numerous health problems like coronary heart disease and some form of cancer rather than smoking, having a poor diet or drinking. Hence people can improve their health and those particularly in relation of coronary heart disease through regular exercise and activities like walking and cycling which are relatively inexpensive activities and which does not require any special skills to perform and it can also easily fit in people`s the daily routine. Hence in regards to that, The Health Education Board of Scotland has been promoting and encouraging walking through it`s campaign named walk about a bit. General health benefits of Outdoor Activity There is a wide range of outdoor activity; for example, Bird Watching may involve walking along with interpreting sounds and visual clues as well as meeting and socialising with other fellow Birdwatchers which contributes to wellness. Similarly, walking itself is known to be the most common outdoor activity and brisk walking for whether one hour per day or three hours a week helps to lower the risk of heart diseases by 30 to 40 percent in women (AARP 2008, citing the 20-Year Nurses Health Study). Therefore, walking have many health benefits specially for older adults which are: managing weight; controlling blood pressure; decreasing risk of heart attack; boosting good cholesterol; lowering risk of stroke; reducing risk of breast cancer and Type 2 diabetes; avoiding need for gallstone surgery; protecting against hip fracture; preventing depression, colon cancer, constipation, osteoporosis, and impotence; lengthening lifespan; lowering stress levels; relieving arthritis and back pain; strengthening muscles, bones, and joints; improving sleep; and elevating overall mood and sense of well-being. Thus, outdoor activities that include walking help to maintain a good health and wellness. In addition, many researchers (Driver and Knopf 1976; Driver and Cooksey 1977; Driver 1985; Godbey et al. 1992; Tinsley et al. 2003; Kaczynski and Henderson 2007) have found beneficial effects of outdoor recreation on two problems in particular which are stress and obesity. Stress and outdoor activity According to Godbey and Blazey (1983), strolling in parks is seen as beneficial to older visitors since it helps in stress reduction and More and Payne (1978), also added that it helps to decrease the level of anxiety, sadness and negative mood by spending time in parks. Hence, the longer people stay in parks, the less stressed they feel (Hull and Michael 1995). The American Institute of Stress (2008) found that 43 percent of adults in U.S suffer from acute or chronic stress. Moreover stress also lead to heart attack, blood pressure and is also linked with obesity (Bell et al. 1998; Brand et al. 2000). Hence, numerous studies have shown that when being in the natural surroundings, people tend to recover quickly and have fever illness (Frumkin 2001; Moore 1981; Ulrich 1984; Parsons et al.1998). therefore performing an activity within the natural environment have a rejuvenating effect over the peoples health while they are in contact with wilderness area (Hartig et al. 1991; Kaplan 1984), community parks (Canin 1991; Cimprich 1993), prairies (Miles et al. 1998). Obesity and outdoor activity Obesity is seen as an epidemic and it is closely linked and contributes to increased risk of disease such as hypertension, diabetes, coronary heart disease, respiratory disease and many others. Although there are multiple causes of obesity and it is not completely understood by researchers, sedentary that is insufficient physical activity is known as one of the factors causing obesity. Between 1991 and 2001 obesity in United States have been steadily studied and it was found that obesity rates have increased to 75 percent among adults and that only 25 percent are engaged in doing recommended activities. Figure 1 below shows more detailed information about obesity rates in California. Figure 1: The Growth of Obesity in California: Percentage of Californias Population Percent (%) Year Source: CDC, 2002a Obesity also affects a large number of children (Milnes, 2008). Children, who are overweight at their younger age, tend to become overweight adults later and this contributes to low self esteem and alienation (Healthlink, Medical College of Wisconsin, January 14, 2009). Furthermore, studies carried out on preschool children showed that being outdoor plays a major role in performing physical activities like playing games with friends (Sallis et al. 2000). Likewise, outdoor temperatures whether hot or cold act as a stimulus and prompt the body to burn more calories than rather being in heated and air conditioned environment. Economic benefits of outdoor recreation According to the research of Mackay (n.d.), outdoor recreation is beneficial to the Scottish economy. Due to the fact that throughout years, to perform any particular activity, people have to move and travel to the specific site, need to spend money on equipment, food and accommodation and this help to bring income in rural areas of Scotland which gives way to new businesses and sustain the economies of these areas. Moreover, according to the survey carried out in 1998 in Scotland, it estimates that 137 million day visit were made to the coast and countryside and on average,  £6.50 were spent by each persons on each visit (National Centre for Social Research 1998). A more detailed survey carried out in 2000 showed that people spent more than  £900 million while participating in walking and other outdoor activities in the countryside and at the coast. Hence, the expenditures were on average people spend  £6.20 per party,  £1.55 was on fuel and  £3.07 was on food and drinks ( NOF System Three Scotland 2000). To explore the economic impact of a multi-use rail trail in Victoria, Australia Beeton (2006) surveyed 140 groups, during Easter 2006, total accounting for 625 people. The length of journey was from 0.5 days to 30 days. The average expenditure per person per day was at about $258, $147 on food and beverage; of which $27 was accommodation; $47 on transport; $10 on cycling and $27 on other. The average economic contribution per person was $482.94(after the application of multipliers). The social benefits of outdoor recreation Outdoor recreation is often regarded as having positive impacts on the society. The physical benefits of outdoor recreation on health have been well documented by researchers but not much emphasis is made on the social benefits linked with these activities. Some of the social benefits of recreation are known as reduced crime rate, promotes stewardship, encourage voluntarism and strengthen the communities. According to the Californian mayors, they believe that parks and recreation facilities helps to strengthen and bring communities together (DPR, 2002). Similarly, 77 percent of Los Angeles citizens were surveyed after the riots of 1993 and they listed that improved parks and recreation facilities are important or Absolutely critical to the restoration of their community (TPL, 1994). Participating in recreation activities helps to promote voluntarism. Hence, adults who frequently use parks and recreation facilities and who participate in recreation programs are generally the one who volunteered rather the one who does not use these services (Busser and Norwalk, 2001). Moreover, following a survey, 95 percent of Americans agreed that outdoor recreations help to generate appreciation for the nature and surrounding (ARC, 2000). Faulks et al (2007, p. 11) found that research conducted on the Central Otago Rail Trail in New Zealand showed that the range of social benefits to the community due to the rail trail, both as a resource and as a place of physical activity, included: Mental and physical well-being for participants; Education benefits regarding an understanding about working on a railroad; Bringing families together; Meeting like-minded people; Introducing new people into the community; and Generating a sense of pride and a heightened community identity. Outdoor Education There has been a wide range of outdoor programs that have been conducted within educational contexts in recent research which include the Duke of Edinburgh style programs (Bailey, 2004), that is Extended Stay Outdoor Education Programs (ESOEPà ¢Ã¢â€š ¬Ã… ¸s) (Gray, 1997; McLeod Allen-Craig, 2007), cross-curriculum programs (Eglington Broderick, 2008; Haddock, 2007a), environmental education centres (Ballantyne Packer, 2007) as well as several traditional outdoor education programs (Hales, 2006; Haskell, 2000; Purdie, Neill, Richards, 2002). Moreover, from such diverse programs, the results reported were also wide-ranging. Hence, by participating in the Duke of Edinburgh program, it showed improved relationships among the participants and also problem solving skills and self confidence had been enhanced which have resulted in gain in academic achievement due to involvement in outdoor education programs (Haddock, 2007a, 2007b). in addition through these programs, students have been able to learn and apply eight dimension which are: Time management; Social competence; Achievement motivation; Intellectual flexibility; Task leadership; Emotional control; Active initiative; and Self-confidence. On average, outdoor education programs appear to have a small to moderate effect on participants perceptions of their own qualities and capabilitiesà ¢Ã¢â€š ¬Ã‚ ¦(roughly equivalent to à ¢Ã¢â€š ¬Ã‚ ¦ other types of self-concept change programs). These results are a positive endorsement of outdoor education as a legitimate and effective educational training method Outdoor education definitely has something to offer. (Neill and Richards, 1998, p7) Sport, recreation and tourism Understanding the motivations and expectations of participants is essential when trying to provide outdoor programs. Kiewa (2001) carried out a qualitative study using in-depth interviews and diary entries of rock-climbers. She analysed the responses of 14 females and 17 males over a 12-month period, attempting to develop an understanding of the role of gender and motivations and reasons in practicing these sports. The result showed that outdoor adventure programs are constructed with the view that both men and women will benefit from programmes designed to support skills associated with the opposite genderà ¢Ã¢â€š ¬Ã… ¸ (Kiewa, 2001, p.11). Furthermore, in seeking to understand the needs, expectations motivations and of participants, another survey was carried out on a different adventure sport which was rafting trip near Melbourne. The research showed that there were significant differences in the motivations and needs of the participants. While the newer participant tend to focus more on the challenges of the activity, the frequent and experienced ones focus more on the ancillary benefits like spending time with friends and family, resting and relaxing in outdoor environment (Fluker Turner, 2000). In addition, in a less challenging context, two surveys were carried out on visitors to Mt Kosciuszko where more than 2,000 people may visit the summit during peak periods on any one-day. The earlier survey was conducted during Easter 2005 and had 494 participants while the other one was conducted over summer 2005/6 and had 2,492 responses (2007b; 2007c). In each case, visitors both expected and experienced wilderness, even though there are several structures to protect the environment. The main factor that motivates the participants to visit Mt Kosciuszko, was the scenic beauty and nature then followed by enjoying the outdoors and climbing. For more than 50% of respondents, encountering and experiencing wilderness was very important to them. Although, due to high level visitation subsequent track management work, visitors still had high satisfaction level just by participating and experiencing the nature of the area Factors motivating outdoor participation A growing number of research supports the proposition that individuals who live in activity friendly environments are more likely to be physically active during their leisure time (Sallis et al. 2000; Humpel et al. 2002; Killingsworth 2003; Owen et al. 2004). Active Living Research summarizes the important facts of such research which are: the proximity, supply, safety and design of recreational spaces. Other well known factor influencing participation is the availability of leisure time. The following subsections consider these variables. Leisure Time On average, Americans have 35 to 40 hours of free time per week (Robinson and Godbey 1999; BLS 2006). However, the majority of this time comes in small portions during weekdays, rather than in big blocks on weekends. Hence, watching TV takes up about half of all free time (Table 5) and adding to this, 27 hours per month goes on Internet use for both work and leisure (Nielsen and Hansen 2007). By contrast, sports, exercise and outdoor recreation account for only about 8.5 hours per month. Therefore, outdoor recreation, then, is comparatively rare. Moreover, if travelling is considered as an indoor activity, most Americans spend 95 percent of their time indoors (Robinson and Godbey 1999). Table 5: Americans Leisure Time, 2006 Leisure activity Average minutes per day Watching TV 156 (2.6 hours) Socializing, communicating 46 Other leisure activities 29 Reading 22 Relaxing, thinking 19 Playing games, using computer for leisure 19 Sports, exercise, recreation 17 Total 308 (5.1 hours) Note: Data include persons ages 15 and older. Data include all days of the week and are annual averages. Source: American Time Use Survey, U.S. Bureau of Labor Statistics, 2006. Furthermore, while being on vacation, people spend more time outdoors, like walk more, and watching TV less (Robinson and Godbey 1999). Vacations then alleviate perceived job stress and burnout (Westman and Etzion 2001). In short, vacationing may be good for ones health (Gump and Matthews 2000). Proximity to Outdoor Spaces Proximity to outdoor recreation is a critical variable in explaining participation rates. Creating and improving the recreational facilities and spaces can spark a 25 percent increase in those who exercise at least three times per week (CDC 2002). Hence, the closer people live to a bikeway, the more likely they are to use it (Troped et al. 2001). Moreover, Kaczynski and Henderson (2007) summarize the facts founds concerning the role of park proximity in physical activity. In addition, eight of 13 articles indicated positive associations between physical activity and park proximity. For example, a survey conducted on U.S. adults showed that perceived access to parks and recreational facilities were related to increased physical activity (Brownson et al. 2001). Similarly, adults in New York City, Baltimore, and North Carolina, were 28 percent more likely to engaged in recreation activities if the parks and recreation facilities was within five miles of their home. Likewise, having faci lities within one mile encouraged higher levels of physical activity among African Americans and Hispanics (Diez-Roux et al. 2007). Safety of Parks Powell et al. (2003) reported that four studies which were carried out found no significant relation between safety aspect and walking in ones neighborhood, but the three other studies found such a relation. One of the latter indicated that recommended activity levels were met by 43 percent of peoples who had safe places to walk within 10 minutes of home and on the contrary only 27 percent of those without safe places (Powell et al. 2003). An onsite survey in a large metropolitan park revealed that among older adults, female park visitors had significantly more fear of crime than did males (Raymore and Scott 1998). Fear of crime was found to be an important factor, and former crime victims (9 percent of all those surveyed) were particularly fearful. Respondents reported that traveling to and from the park were more worrisome than being in the park itself. Supply of Outdoor Spaces The number parks and playgrounds in a community are related positively to physical activity levels. For instance, a study of some 500 adults from 56 neighborhoods in Oregon, Portland, found that both the area of green or open space and the number of recreation facilities were related to high levels of physical activity (Li et al. 2005). Although the number parks and green spaces in a community positively influence on physical activity, researchers cannot say that large parks are no more likely to be associated with higher levels of physical activity than smaller parks. For example, a study of four neighborhoods in Ontario found no such relationship between the size of parks and their use for physical activity (Kaczynski et al. 2008). The provision of facilities The benefits of engaging in physical activities, particularly outdoor activities, are dependent on the type of infrastructure provided to participant. According to Aldous (2006), he noted that in the context of leisure planning, providing adequate infrastructure and green spaces in urban areas was important in creating and broadening appreciation for the nature and environment. Similarly, Crilley (2007) studied the theme of infrastructure provision to understand the important attributes of trails. Hence, it resulted in the five top trail attributes were: easily accessible; the trail should be safe; well-maintained surface, have adequate signage along the trail and that the trail should be well maintained. Park and Playground Design and Features Parks with soccer fields, courts, basketball courts, volleyball courts, tennis and racquetball and playgrounds were associated from moderate to vigorous levels activity (Floyd et al. 2008). In another study, some researchers have examined 28 features of ball fields, bike paths, and so forth in 33 parks they found that parks with several features were more likely to be used for physical activity rather than parks with fewer features. Moreover, according to Kaczynski et al. (2008) parks with paved trails, for instance, were 26 times more likely to be used for physical activity than parks without paved trails. A study of four park types (neighborhood park, waterfront park, city park, extreme park) showed that levels of moderate or vigorous activity were highest in the areas having courts, sports fields, playgrounds, and paths, whereas sedentary activity was observed in open green spaces (Shores and West 2008).

Abandoned Oil Wells End of Field Life

Abandoned Oil Wells End of Field Life ABSTRACT As petroleum, production continues to decline in many parts of the globe, more operators are seeing well abandonment as a reality. Drilled wells are plugged and abandoned for different reasons of which the typical and operational reason is that the well has reached its economic limit or when drilled it was found to be a dry hole. (refer). According to Ide, T., et al 2006, well bore is taken to be high fluid transmittal pathway. Even with the current procedure of sealing and abandonment, individual wells have the tendency to loose their integrity due to various factors, which include but not limited to poor cementation, poor or ineffective plugging, and increase in formation pressure after abandonment, corrosion of casing (refer). Safe and economical well abandonment are important to the industry from environmental and financial standpoints. Improper abandonment can require re-abandonment procedures to mitigate environmental contamination or to comply with updated regulations, causing an increased financial burden on the operator. 1. Introduction 1.1 BACKGROUND All wells drilled have a distinct life cycle with respect to its cost, duration, recovery, and value. Although these characteristics and attributes are specific to an individual drilled well, all producing wells pass through the same initial and final state, beginning with completion and ending with abandonment. After the drilling stage of a well and the target depth is reached, a decision to complete the well is made based on the reservoir attributes: is the well dry or is the hydrocarbon in place of economic value. Ultimately, every well becomes dormant because of reduced economic returns or technical problem. When a well stops producing, it either may be shut-in (SI), temporary abandoned (TA) or permanently abandoned (pa). With ageing fields fast approaching their economic limit, abandonment is becoming increasingly frequent and many operators have to modify their abandonment procedure to fit the Wellbore condition and make certain that abandoned wells remain permanently sealed and prevent commingling while balancing the environmental objectives of abandonment and cost of actual abandonment. Wells, which are not abandoned appropriately, can become a major hazard to the underground source of drinking water and possibly the aquatic environment [8] Shut in status (SI) When a well is shut-in it is still flowing but its Christmas tree, SV, wing valves are all closed. Usually a well is shut-in if there is a technical or operational problem, which is believed to be temporary. There is no maximum time for a well to remain in shut-in status as long as it is regularly maintained according to regulatory requirement and procedures. Temporary abandonment status (TA) A well is said to be temporarily abandoned when the wellhead is removed and the producing interval is isolated with a plug and the casing is plugged below the mud line. REASONS FOR ABANDONMENT There are various reasons why a well is abandoned, these are: END OF FIELD LIFE ABANDONMENT Drilled wells must at one point in time be abandoned. Before a well reaches the point at which it has to be abandoned it passes through various stages in its life cycle; it begins with the survey and exploitation of an area for signs on hydrocarbon [1]. This leads to a rewarding and exciting discovery of an accumulation of hydrocarbon deposit. This is followed by the acquired Data Processing stage and finally the drilling process. During drilling, the well is created by the use of drill bit and cased off at specific as drilling progresses. Another fulfilling target is reached when the first hydrocarbon is produced a process which unfortunately eventually proceeds the declining period where the rate of hydrocarbon production decreases. However, successful enhanced oil recovery techniques often than not make this stage rewarding financially as it extends the life of the well [1]. When all enhanced oil recovery technique has been employed, and the cost of producing the well is no longer economically viable, the next process is abandonment; a stage not so welcomed by most operators as it means the cessation of production. Dry hole Abandonment A drilled well is also abandoned when after drilling, the hole was found to be a dry hole. Though abandonment is meant to be a permanent termination, the effect is felt for many years more than that of the short producing life of the well. The main goal of any plugging and abandonment is to provide a permanent and effective isolation of fluids all along the subsurface formation in the different layers where they were enclosed prior to plugging, thereby preventing fluid migration and reduce environmental risks of contamination and prevent costly remedial jobs [1]. To achieve this several significant intervals of the well must be filled and tightly closed with a sealant material from bottom hole to the surface with special attention paid to the production interval [4] and zones of high differential pressure and temperature. The material used for plugging differ depending on what type of well is being abandoned, for oil and gas well the material used is normally cement based materials, for water well, cement based as well as bentonite can be used to isolate the different intervals[4][ PUT UNDER CEMENT PLUG CHARACTERISTICS UNDERE INTEGRITY OF ABANDONED WELLS. The integrity of the abandoned well can fail for very many reaso ns such as plug failure, poor slurry design etc. A cement plug can fail to set at the desired location as cement slurry often has the tendency to fall through the lighter drilling fluid below it [9]. Failure can also be as a result of downhole changes which may occur after the well has been abandoned [8]. Over the years, techniques for drilling and completion of hydrocarbon wells have continued to evolve. This drive for new technology for hydrocarbon recovery is due to the need to maximize hydrocarbon recovery while protecting the environment [4]. The evolution of well abandonment techniques has been much slower than that of drilling and completion. This is because abandonment is considered a sunk cost [4]. Project Objective The objectives of this thesis is to review the factors which contribute to the overall integrity of abandoned wells. These include, well parameters, cement placement techniques, casing integrity. These play an important role in the design, construction and actual execution of the abandonment project. In the abandonment of wells, the factors that contribute to the integrity differ depending on the wells. This is because each well is a unique entity and hence has to have independent well abandonment design. PROJECT METHODOLOGY In this work I intend to talk about For instance, in a well where a fish is lost in hole the abandonment design has to taken into consideration remedial action or ways to set the cement plug as there may be no access to the bottom hole to set a bottom plug in the sump. Abandoned wells can be a cause of concern due to their potential to act as path for flow between formations, which under normal circumstance are isolated including underground sources of drinking water, of great concern are those abandonments with faulty plugs, compromised casing and those having cracks in the cement [7]. This work is aimed at highlighting the different factors which contribute to the integrity of an abandoned well. ( reorder and rewrite) Chapter 2 Literature review Well abandonment has come a long way since the first discovery of oil and gas, with the increasing awareness of the importance of environmental protection, the need to improve the processes of abandonment has now become a major concern for many operators, as abandoned wells are considered a possible conduit for fluid flow between different formations. According to C. H. Kelm et al, the objective of abandonment of a well must taken into consideration the need to do so in a best practices manner by examining the following fundamental aim of any abandonment process; The need to protect any hydrocarbon left in the pay zone of the formation drilled. The need to preserve and prevent contamination of freshwater zones (for onshore rigs) penetrated during the course of drilling the well. Avert of any contamination of the surface environment. For instance, in the case of vegetation, air pollution and marine environment. The need to abide by all regulatory requirements stated in during the abandonment. In the past years many papers has been published on areas ranging from alternative plugging technique, self healing and expandable cement, improved cement slurry design, placement technique with the aim to reduce the cost of abandonment and improve the abandonment. Abandoned well in an oil field are sealed using a plugging material according to regulatory requirements. A perfect example of a plugging material in the ideal sense according to D.G Calvert et al 1994 is one, which can be pumped down the drilled hole, has the ability to harden in a reasonable time, and bond with the walls of the drilled formation and casing in order to prevent fluid flow from one formation to another. While regulations vary from place to place, the general practice involves plugging the Wellbore with a Portland cement material specifically designed for the isolation purpose. In his review of plugging and abandonment techniques, D. G. Calvert et al, stated that the cement mixture used in oil and gas vary d epending on the type of hole is to be isolated. Very few papers has been published that focuses on the integrity of the actual well after abandonment. Liversidge, D. et al. in his work on permanent plug and abandonment solution for the Northsea he presented case histories of the Brent South field abandonment project done using both class G cement with an expandable agent system and flexible cement according to the current stringent regulation. Cement integrity preservation during well completion, production phases as well as during abandonment is of critical importance for long-term protection. In the past years numerous papers and texts in the area of cement sheath failure, improved flexible and expanding cement and related topics have been published, indicating the increasing need to improve well abandonment and reduce cost. Examples of works published include but not limited to (Bosma et al 2000), (Ravi et al. 2002), (Glessner et al., 2005), (Mainguy et al., 2007), (D. G calvert et al., 1994), (Locolier et al., 2006),( Liversidge et al., 2006). Although many papers have been written, very little work has been done to investigate the cement plug integrity after abandonment. The ascribed cause to this may be that permanent abandonment is considered a non-profit venture. Mainguy M. et al., 2007 carried out an analysis of the probability of failure of cement plugs when subjected to varying compressive and tensile load using an ideal reservoir model designed to suit changes in the downhole condition. In his study he identified that there is a greater tendency for the material used to seal zones for abandonment to fail in wells situated where there is instability in the pressure, temperature and stress state due to changes that occur downhole. He concluded that when the plug is subjected to maximum tensile stress it failed due to the low tensile strength of the conventional class G cement. Though he suggested the use of pre-stressed cement as they adapt more to changes downhole, his work did not cover the problem of rock-cement de-bonding which is a problem that greatly reduces the sealing capacity of cement. In the study done by R.C. Smith et al., 1984, on the successful method of setting cement plug, he investigated the ongoing failures of cement plug s due to the instability caused by the difference between the density of the cement and the drilling mud. In his work, he suggested the use of mud thickened with bentonite before spotting the cement so as to allow a greater density difference. With respect to the problem of controlling the direction of flow of the cement slurry a diverter placed at the end of the tubing to help divert the direction of flow and improve stability. Drilling fluid can also be used as a plugging material by adding a cementitous additive. The additive can either be fly ash of blast furnace slag which have the characteristics of a cement as they harden when the mixed with water. Cement is not naturally occurring but manmade and like any other manmade material, it is expected to age, wear-off, and, degrade overtime under different subsurface condition, which may differ from the time it was initially set [W. Zhou et. al 2005]. Plugging oil well is a common operation, which is increasing as mature field reach the end of their producing life. In general, plugging and abandonment of a well involves filling a certain length of casing or open hole with a volume of cement mixture designed for it in order to provide adequate sealing against upward migration of formation fluid. After the cement plug is place in the desired location it is left to harden over time. The placement of the cement plug is a major part of abandonment, as failure of this will cause commingling of fluids from different formation. The setting and spotting of cement plugs can be done in various ways depending on the wellbore condition and regulatory requirement. A review of the worldwide acceptable plugging procedure shows the a minimum of three cement plugs is required of which two are, the first plug is put in place by squeezing the cement plug through the perforation into the former producing zone in order to seal off any further influx of reservoir fluid into the Wellbore[2]. The second plug is usually set towards the middle of the Wellbore or near a protective casing shoe. Finally the third plug is set about200- 300ft below the mud line. In general, the length of a plug ranges from 100to 200ft depending on the regulatory requirements. Any additional plug set is dependent on the well bore condition. Although observations and studies show that cement plugs have the ability to perform as expected for up to several decades, uncertainty exists that the material can maintain its isolation integrity for several thousands of years. Recent study shows that abandoned wells in which CO2 was used in the enhanced oil recovery technique prior to abandonment have the potential to leak and allow CO2 migration notwithstanding the fact that the well has been properly abandoned [Scherer, G.W et al, 2005]. This is mainly due to corrosion and degradation of the casing and cement. This degradation and corrosion occurs when carbonic acid formed from the dissolution of CO2 in brine attacks the cement and casing [Scherer, G.W et al, 2005] a process, which is dependent on the temperature of the formation, cement composition, brine and the rock mechanics and composition. Potential leakage of reservoir fluids through degraded cement plugs is hence of primary concern. Various work on inter-formational flow shows that there is still the possibility of flow between formations even with a successful plugging of different interval. This case can arise when the abandoned well is near an active well. Javandel et al developed the first analytical model; their model showed the possible of flow to an upper formation in response to a lower injection pressure build up in a lower formation. Striz and wiggings carried out further work by developing a coupled model to predict flow using a steady state approach to create a transient flow. This model can be used to developed abandoned fluid flow using available field data. In recent studies, statistics show that in the US one in every three well drilled for hydrocarbon is dry and have to be plugged and abandoned[D.G Calvert, et al 1994]. Wells are drilled for various reasons ranging from industrial, oil and gas, to municipal uses, but in the end these well have to be abandoned [D.G Calvert, et al 1994]. Some wells were abandoned before any regulation and guidelines were defined, these wells may have either been plugged improperly or not plugged at all and these now poses a threat to the quality of the groundwater. For the aim of regulating bodies to be achieved i.e. achieving underground water protect and hence environmental protect, the operating companies must understand that following the different regulatory requirement alone is not sufficient to guarantee a lasting protection of the environment [4]. It is sometimes difficult for operators to abide by the regulatory requirements as well as developing a plan which would both serve to seal off the reservoir and provide long-term protection of the environment while justifying the overall cost in general [4]. Currently there is a high rise in abandonment of ageing and mature field which either have reached their economic limit or are no longer producing (refer). Methods of ABANDONMENT The initial stage of a decommissioning process is the plugging and abandonment of the wells, during this stage, the tubing, casing strings, and, conductors are cut below the mud line and removed, zones are sealed with cement plug to isolate the flow path between the reservoir fluids and other zones as well as the surface. Zones not sealed with cement plug are filled with mud with fluid having the proper weight and consistency to prevent movement of other fluids into the wellbore. Most abandonments follow a general methodology that is adjusted to meet individual well requirements. As procedures can and do change significantly for each well, cement plug design should frequently be attuned to reach minimum wait-on-cement (WOC) times with varying downhole conditions. Near-wellbore geology should be assessed, and the wellbore and annuli properly cleaned to avoid microannuli and poor cement bonding. Traditional techniques include cement squeezes, gel squeezes, and mechanical plugs such as bridge plugs and packers. Cement and gel technologies are mainly used for behind casing repair, and mechanical options are usually confined to plugging the casing. In the general process of abandonment there as basic steps which are followed to ensure successful plug and abandonment program. This includes the planning process, wellbore equipment testing, designing, well geometry assessment. PA PLANNING The most essential decision after when to abandon a well [11] is how. Preparation is a key ingredient in plug and abandonment of a well. In order to abandon a well successfully careful planning and effective plugging and abandonment procedure is crucial to prevent gas or fluids from moving to the surface or to other subsurface formations. In addition to the environmental risks that come with poor seals, corrective plugging may be necessary, increasing the cost and difficulty of abandoning a well. However, operators and service companies have several options for obtaining complete, permanent abandonment. For every well, there is a variation as each well PA is unique and different. The techniques used to achieve this process are generally based on industry practice, research, and conformance with the relevant regulatory compliance requirement. The synthesis of practical knowledge, current technology and regulatory requirements results in the most effective wellbore plugging and abandonment possible. Wellbore equipment testing. A preliminary inspection and survey of the wellhead and wellbore condition is carried out to determine if the valves on the wellhead are in operable condition, if it is found not to be in operable condition they are hot-tapped. The wellbore is surveyed using a slickline unit to check for any obstructions in the well, to confirm measured depth and also to gauge the internal diameter of the tubing. After the survey and removal of the slickline, the annuli and tubing is filled with fluid using a well pump is installed at the wellhead to ascertain an injection rate into the perforations. The tubing and casing are also pressured up to check for integrity. Casing annuli are also pressure tested to check for communication problems between casing strings and to record the test pressure over a period of time. The integrity and reliability of the primary cement is assessed in order to ensure that the cement sheath is still providing isolation across the reservoir and the cap rock. A well control plan is designed to establish reservoir condition and subsequently the contingency responses to any event which may occur during the abandonment process. DESIGN OF A WELL ABANDONMENT PROGRAM Prior to plugging and abandoning a well, a review of the existing well design, record of past work, previous well performance and geologic and reservoir condition is carried out by the operator. The investigation of everything that may relate to the health and safety issues as well as regulatory requirements is also performed, after which the design of the abandonment program begins. The design is done based the existing wellbore and reservoir conditions depending on the findings from the review and investigation. This allows the operator to plan an abandonment program that will satisfy the goal of making the well safe from future resources. PA design needs to be integrated in the planning of the well, and should be considered in a single budget. There are many factors which must be put into consideration in order to design an effective abandonment program , such as, the reservoir status, the integrity of the primary cement, hole cleaning and cement placement technique, the temperatu re and pressure of the well, the type of fluid in the well, the age of the well, the status of the cap rock. Fluid Type Drilled wells produce fluids in liquid and gaseous form, wells which contain sour fluids i.e. sulphur rich would be expected to have accelerated corrosion rates and stress cracking depending on the age and wellbore construction, may impair the capacity to perform plug and abandonment, to mitigate this components which are corrosion resistant can be used. Reservoir status In the design of PA, it is necessary to consider the reservoir status concerning its stability, the current pressure and temperature, the pressure at the initial stages of well development and the permeability of the reservoir both horizontal and vertical. With the information, plug and abandonment is then designed to withstand the pressure of the well after finally reach equilibrium. Cap rock Status It is also necessary to take into consideration the cap rock status i.e. is it still impermeable, has production activities induced fracture or has weathering taken effect. Placing the Plugs After the design and planning of the abandonment program, calculations must be made to determine the amount of cement required and the number of wiper plugs needed to separate the cement plugs from the rest of the fluids. The use of wiper plugs enables the formation of a stable platform on which the cement can be set. A wiper plug is placed in the wellbore, and then a predetermined quantity of cement slurry is pumped on top of it. Because of its weight, the slurry becomes a driving force. The slurry falls to the bottom of the hole, pushing the wiper plug ahead of it and forcing existing air and produced fluids back into the formation. Another plug and perhaps a bit more cement finish the job. In most wells, where there is one permaeble zone, one plug and one volume of cement and the surface plug are all that is needed. In other wells, additional wiper plugs, additional cement slurry, and probably spacers of water or drilling fluid are used consecutively until all of the air and fluid is forced out into the formation, there is zilch pressure on the pipe, and it is apparent from the returns that the whole wellbore is appropriately sealed. The quantity and kind of spacer fluid that can be used is dependent on individual state regulations. The remaining casing at the top of the well is cut off 3 ft below ground level. Along with this general methodology, each region stipulates its own abandonment methods based on field conditions and local regulations as can be seen in the following examples. PA steps in Los Angeles Basin in as follows [12]: The abandonment program is prepared with the support of a qualified engineer. A schematic showing the current mechanical condition of the well is prepared. The geologic condition of the well, including the structure, faulting, and producing zones is assessed. The depth and position of cement plug that will cover the producing zones and any potable water zones if applicable is measured and verified. Choice of whether to use perforating or cavity shots is made. The casing is pressure tested after setting cement retainers. The different equipment required for the job is determined and assembled. Estimate of abandonment/re-abandonment costs is made. In contrast, the steps followed for the Hutton tension-leg platform (TLP) in the East Shetland Basin of the North Sea involved three phases [13]: Perform standalone wireline intervention. Perform drilling unit intervention to set the cement plugs after the first wireline plug has been set. Cut casing 10 ft below the seabed and recover casing stumps. Another abandonment performed in the North Sea followed a different procedure [14]: A permanent cement primary barrier placed immediately above the reservoir. A secondary barrier placed as a back-up to the first barrier. A third barrier then placed near the surface to isolate shallow water-bearing sands. Severed completion tubing and recover wellhead. In Western Canada, the traditional abandonment procedure of wells with casing vent flows included the following: The source of the casing vent flow is estimated or determined. If the source zone is shallower than the producing zone, the producing zone is abandoned. The source zone is perforated. Depending on the feed rate obtained at the estimated source depth, either a bradenhead or a retainer squeeze is performed. Retrievable tools are used as required. Typically, Class G cement with Calcium Chloride and some fluid-loss control is utilized. The slurry is placed and a static squeeze pressure of 7 MPa is attempted. As needed, cement is drilled out and perforations are tested for seal. Often, several attempts are made in order to obtain a static squeeze pressure of 7 Mpa on surface or mitigate the casing vent flow. Techniques for Abandonment The techniques used for plugging and abandonment of drilled well worldwide are generally based on industry practise. These techniques include; Rig Coil tubing unit Rigless abandonment COIL TUBING UNIT The flexibility of coiled tubing has recently been tailored to develop rigless abandonment [15,16]. This method, focuses on harmonizing all well services to accomplish utmost efficiency. Coiled-tubing unit [fig.] abandonment, like any other method, is more effective when appropriate cementing procedure is used from the kick-off of the well, from original zonal isolation with the primary cement sheath to plugging and abandonment. Early prevention of microannulus can help operators obtain a complete final seal. Five main criteria are recommended for optimal abandonment performance with coiled tubing: Mobility; All equipment should be mounted on wheels for increased mobility. Self-sufficiency; the service company provides nearly all activities. Dry location; Fluids are not drained on or near the wellsite. Single operation; the job is completed in one visit to the wellsite. Low mileage; Move time is reduced and transport optimized for maximum efficiency in unit and camp moves. In this abandonment technique geological consideration like the type and condition of the reservoir and caprock formations are take into account. Permanent seals typically must be made between producing zones and at impermeable caprock formations. The condition and configuration of cement, perforations, tubulars, and downhole equipment are also considered. In addition to providing complete, permanent seals, the use of coiled-tubing can help increase abandonment efficiency. This method can provide the following advantages: Increased tripping speeds Increased rig-move efficiency Precise placement of cement plugs; exact spotting of plugs at the interval of interest even in deep well as coil tubing can be reciprocated while pumping. Suitable for use on live wells; it is possible to run CTU for remedial cement squeeze in live well as the wellbore can be controlled using the BOP and stripper assembly. No need to pull production tubing; existing tubing and wellheads do not have to be removed to access the producing interval. Success using the coil tubing method has been recorded in Oman. REGULATORY REQUIREMENT FOR ABANDONMENT IN THE NORTHSEA AND USA In the early years on the oil and gas industry, many wells were drilled and some were found to be dry and subsequently were abandoned without much consideration given to the manner in which the wells were abandoned. Sometimes tree stumps were thrown in the well as a means to plug it [3], during this era the preservation of the groundwater, in general, the environment was not a major issue, and there was no defined regulation by the oil states or agencies. During the tail end of the 1930s different states and agencies in the US started establishing regulations, this defined requirement to ensure better well abandonment [D.G Calvert, et al 1994]. The number of regulation guiding well abandonment has risen along with the rising need to protect the environment in countries around the world. Today most countries have some form of regulation that addresses well abandonment requirement; though these regulations are not uniform and differ from country to country and body to body, they provide a minimum standard for operating companies. For instance for the state of California in the United States of America, the different governing bodies have their own regulations which are as follows; Minerals Management Services (MMS): The basic plugging requirements are found in 30 CFR 250.110 Subpart G. Department of Conservation, Division of Oil: Gas, and Geothermal Resources (DOC) The California Code of Regulations Title 14 Division 2, Chapter 4 beginning with Section 1745 focuses on the fundamental plugging requirements. California State Lands Commission (CSLC): The fundamental plugging requirements in the California Code of Regulations Title 2 Section 2128(q). Abandonment in the North Sea In the North Sea as in US, the regulations differ. The different countries that make up the North Sea have their different governing bodies and subsequently different regulation. The law in the UK, Norway, Denmark and Holland holds the last operator of a well accountable and responsible to pay for all the cost incurred in permanently abandoning the well. It also holds them accountable for any leakage and any clean up that may be required in the event of a leak. Abandonment programs in the Northsea are designed to meet the guidelines for abandonment issued by the operation association or government. For the UK sector of the north sea, abandonment guidelines is issued by the UKOOA, similarly for the Norwegian sector the guidelines are contained in the NORSOK/PTIL D-010 standard and for the Netherlands it is contained in the Dutch Mining Abandoned Oil Wells End of Field Life Abandoned Oil Wells End of Field Life ABSTRACT As petroleum, production continues to decline in many parts of the globe, more operators are seeing well abandonment as a reality.

( reorder and rewrite) Chapter 2 Literature review Well abandonment has come a long way since the first discovery of oil and gas, with the increasing awareness of the importance of environmental protection, the need to improve the processes of abandonment has now become a major concern for many operators, as abandoned wells are considered a possible conduit for fluid flow between different formations. According to C. H. Kelm et al, the objective of abandonment of a well must taken into consideration the need to do so in a best practices manner by examining the following fundamental aim of any abandonment process; The need to protect any hydrocarbon left in the pay zone of the formation drilled. The need to preserve and prevent contamination of freshwater zones (for onshore rigs) penetrated during the course of drilling the well. Avert of any contamination of the surface environment. For instance, in the case of vegetation, air pollution and marine environment. The need to abide by all regulatory requirements stated in during the abandonment. In the past years many papers has been published on areas ranging from alternative plugging technique, self healing and expandable cement, improved cement slurry design, placement technique with the aim to reduce the cost of abandonment and improve the abandonment. Abandoned well in an oil field are sealed using a plugging material according to regulatory requirements. A perfect example of a plugging material in the ideal sense according to D.G Calvert et al 1994 is one, which can be pumped down the drilled hole, has the ability to harden in a reasonable time, and bond with the walls of the drilled formation and casing in order to prevent fluid flow from one formation to another. While regulations vary from place to place, the general practice involves plugging the Wellbore with a Portland cement material specifically designed for the isolation purpose. In his review of plugging and abandonment techniques, D. G. Calvert et al, stated that the cement mixture used in oil and gas vary d epending on the type of hole is to be isolated. Very few papers has been published that focuses on the integrity of the actual well after abandonment. Liversidge, D. et al. in his work on permanent plug and abandonment solution for the Northsea he presented case histories of the Brent South field abandonment project done using both class G cement with an expandable agent system and flexible cement according to the current stringent regulation. Cement integrity preservation during well completion, production phases as well as during abandonment is of critical importance for long-term protection. In the past years numerous papers and texts in the area of cement sheath failure, improved flexible and expanding cement and related topics have been published, indicating the increasing need to improve well abandonment and reduce cost. Examples of works published include but not limited to (Bosma et al 2000), (Ravi et al. 2002), (Glessner et al., 2005), (Mainguy et al., 2007), (D. G calvert et al., 1994), (Locolier et al., 2006),( Liversidge et al., 2006). Although many papers have been written, very little work has been done to investigate the cement plug integrity after abandonment. The ascribed cause to this may be that permanent abandonment is considered a non-profit venture. Mainguy M. et al., 2007 carried out an analysis of the probability of failure of cement plugs when subjected to varying compressive and tensile load using an ideal reservoir model designed to suit changes in the downhole condition. In his study he identified that there is a greater tendency for the material used to seal zones for abandonment to fail in wells situated where there is instability in the pressure, temperature and stress state due to changes that occur downhole. He concluded that when the plug is subjected to maximum tensile stress it failed due to the low tensile strength of the conventional class G cement. Though he suggested the use of pre-stressed cement as they adapt more to changes downhole, his work did not cover the problem of rock-cement de-bonding which is a problem that greatly reduces the sealing capacity of cement. In the study done by R.C. Smith et al., 1984, on the successful method of setting cement plug, he investigated the ongoing failures of cement plug s due to the instability caused by the difference between the density of the cement and the drilling mud. In his work, he suggested the use of mud thickened with bentonite before spotting the cement so as to allow a greater density difference. With respect to the problem of controlling the direction of flow of the cement slurry a diverter placed at the end of the tubing to help divert the direction of flow and improve stability. Drilling fluid can also be used as a plugging material by adding a cementitous additive. The additive can either be fly ash of blast furnace slag which have the characteristics of a cement as they harden when the mixed with water. Cement is not naturally occurring but manmade and like any other manmade material, it is expected to age, wear-off, and, degrade overtime under different subsurface condition, which may differ from the time it was initially set [W. Zhou et. al 2005]. Plugging oil well is a common operation, which is increasing as mature field reach the end of their producing life. In general, plugging and abandonment of a well involves filling a certain length of casing or open hole with a volume of cement mixture designed for it in order to provide adequate sealing against upward migration of formation fluid. After the cement plug is place in the desired location it is left to harden over time. The placement of the cement plug is a major part of abandonment, as failure of this will cause commingling of fluids from different formation. The setting and spotting of cement plugs can be done in various ways depending on the wellbore condition and regulatory requirement. A review of the worldwide acceptable plugging procedure shows the a minimum of three cement plugs is required of which two are, the first plug is put in place by squeezing the cement plug through the perforation into the former producing zone in order to seal off any further influx of reservoir fluid into the Wellbore[2]. The second plug is usually set towards the middle of the Wellbore or near a protective casing shoe. Finally the third plug is set about200- 300ft below the mud line. In general, the length of a plug ranges from 100to 200ft depending on the regulatory requirements. Any additional plug set is dependent on the well bore condition. Although observations and studies show that cement plugs have the ability to perform as expected for up to several decades, uncertainty exists that the material can maintain its isolation integrity for several thousands of years. Recent study shows that abandoned wells in which CO2 was used in the enhanced oil recovery technique prior to abandonment have the potential to leak and allow CO2 migration notwithstanding the fact that the well has been properly abandoned [Scherer, G.W et al, 2005]. This is mainly due to corrosion and degradation of the casing and cement. This degradation and corrosion occurs when carbonic acid formed from the dissolution of CO2 in brine attacks the cement and casing [Scherer, G.W et al, 2005] a process, which is dependent on the temperature of the formation, cement composition, brine and the rock mechanics and composition. Potential leakage of reservoir fluids through degraded cement plugs is hence of primary concern. Various work on inter-formational flow shows that there is still the possibility of flow between formations even with a successful plugging of different interval. This case can arise when the abandoned well is near an active well. Javandel et al developed the first analytical model; their model showed the possible of flow to an upper formation in response to a lower injection pressure build up in a lower formation. Striz and wiggings carried out further work by developing a coupled model to predict flow using a steady state approach to create a transient flow. This model can be used to developed abandoned fluid flow using available field data. In recent studies, statistics show that in the US one in every three well drilled for hydrocarbon is dry and have to be plugged and abandoned[D.G Calvert, et al 1994]. Wells are drilled for various reasons ranging from industrial, oil and gas, to municipal uses, but in the end these well have to be abandoned [D.G Calvert, et al 1994]. Some wells were abandoned before any regulation and guidelines were defined, these wells may have either been plugged improperly or not plugged at all and these now poses a threat to the quality of the groundwater. For the aim of regulating bodies to be achieved i.e. achieving underground water protect and hence environmental protect, the operating companies must understand that following the different regulatory requirement alone is not sufficient to guarantee a lasting protection of the environment [4]. It is sometimes difficult for operators to abide by the regulatory requirements as well as developing a plan which would both serve to seal off the reservoir and provide long-term protection of the environment while justifying the overall cost in general [4]. Currently there is a high rise in abandonment of ageing and mature field which either have reached their economic limit or are no longer producing (refer). Methods of ABANDONMENT The initial stage of a decommissioning process is the plugging and abandonment of the wells, during this stage, the tubing, casing strings, and, conductors are cut below the mud line and removed, zones are sealed with cement plug to isolate the flow path between the reservoir fluids and other zones as well as the surface. Zones not sealed with cement plug are filled with mud with fluid having the proper weight and consistency to prevent movement of other fluids into the wellbore. Most abandonments follow a general methodology that is adjusted to meet individual well requirements. As procedures can and do change significantly for each well, cement plug design should frequently be attuned to reach minimum wait-on-cement (WOC) times with varying downhole conditions. Near-wellbore geology should be assessed, and the wellbore and annuli properly cleaned to avoid microannuli and poor cement bonding. Traditional techniques include cement squeezes, gel squeezes, and mechanical plugs such as bridge plugs and packers. Cement and gel technologies are mainly used for behind casing repair, and mechanical options are usually confined to plugging the casing. In the general process of abandonment there as basic steps which are followed to ensure successful plug and abandonment program. This includes the planning process, wellbore equipment testing, designing, well geometry assessment. PA PLANNING The most essential decision after when to abandon a well [11] is how. Preparation is a key ingredient in plug and abandonment of a well. In order to abandon a well successfully careful planning and effective plugging and abandonment procedure is crucial to prevent gas or fluids from moving to the surface or to other subsurface formations. In addition to the environmental risks that come with poor seals, corrective plugging may be necessary, increasing the cost and difficulty of abandoning a well. However, operators and service companies have several options for obtaining complete, permanent abandonment. For every well, there is a variation as each well PA is unique and different. The techniques used to achieve this process are generally based on industry practice, research, and conformance with the relevant regulatory compliance requirement. The synthesis of practical knowledge, current technology and regulatory requirements results in the most effective wellbore plugging and abandonment possible. Wellbore equipment testing. A preliminary inspection and survey of the wellhead and wellbore condition is carried out to determine if the valves on the wellhead are in operable condition, if it is found not to be in operable condition they are hot-tapped. The wellbore is surveyed using a slickline unit to check for any obstructions in the well, to confirm measured depth and also to gauge the internal diameter of the tubing. After the survey and removal of the slickline, the annuli and tubing is filled with fluid using a well pump is installed at the wellhead to ascertain an injection rate into the perforations. The tubing and casing are also pressured up to check for integrity. Casing annuli are also pressure tested to check for communication problems between casing strings and to record the test pressure over a period of time. The integrity and reliability of the primary cement is assessed in order to ensure that the cement sheath is still providing isolation across the reservoir and the cap rock. A well control plan is designed to establish reservoir condition and subsequently the contingency responses to any event which may occur during the abandonment process. DESIGN OF A WELL ABANDONMENT PROGRAM Prior to plugging and abandoning a well, a review of the existing well design, record of past work, previous well performance and geologic and reservoir condition is carried out by the operator. The investigation of everything that may relate to the health and safety issues as well as regulatory requirements is also performed, after which the design of the abandonment program begins. The design is done based the existing wellbore and reservoir conditions depending on the findings from the review and investigation. This allows the operator to plan an abandonment program that will satisfy the goal of making the well safe from future resources. PA design needs to be integrated in the planning of the well, and should be considered in a single budget. There are many factors which must be put into consideration in order to design an effective abandonment program , such as, the reservoir status, the integrity of the primary cement, hole cleaning and cement placement technique, the temperatu re and pressure of the well, the type of fluid in the well, the age of the well, the status of the cap rock. Fluid Type Drilled wells produce fluids in liquid and gaseous form, wells which contain sour fluids i.e. sulphur rich would be expected to have accelerated corrosion rates and stress cracking depending on the age and wellbore construction, may impair the capacity to perform plug and abandonment, to mitigate this components which are corrosion resistant can be used. Reservoir status In the design of PA, it is necessary to consider the reservoir status concerning its stability, the current pressure and temperature, the pressure at the initial stages of well development and the permeability of the reservoir both horizontal and vertical. With the information, plug and abandonment is then designed to withstand the pressure of the well after finally reach equilibrium. Cap rock Status It is also necessary to take into consideration the cap rock status i.e. is it still impermeable, has production activities induced fracture or has weathering taken effect. Placing the Plugs After the design and planning of the abandonment program, calculations must be made to determine the amount of cement required and the number of wiper plugs needed to separate the cement plugs from the rest of the fluids. The use of wiper plugs enables the formation of a stable platform on which the cement can be set. A wiper plug is placed in the wellbore, and then a predetermined quantity of cement slurry is pumped on top of it. Because of its weight, the slurry becomes a driving force. The slurry falls to the bottom of the hole, pushing the wiper plug ahead of it and forcing existing air and produced fluids back into the formation. Another plug and perhaps a bit more cement finish the job. In most wells, where there is one permaeble zone, one plug and one volume of cement and the surface plug are all that is needed. In other wells, additional wiper plugs, additional cement slurry, and probably spacers of water or drilling fluid are used consecutively until all of the air and fluid is forced out into the formation, there is zilch pressure on the pipe, and it is apparent from the returns that the whole wellbore is appropriately sealed. The quantity and kind of spacer fluid that can be used is dependent on individual state regulations. The remaining casing at the top of the well is cut off 3 ft below ground level. Along with this general methodology, each region stipulates its own abandonment methods based on field conditions and local regulations as can be seen in the following examples. PA steps in Los Angeles Basin in as follows [12]: The abandonment program is prepared with the support of a qualified engineer. A schematic showing the current mechanical condition of the well is prepared. The geologic condition of the well, including the structure, faulting, and producing zones is assessed. The depth and position of cement plug that will cover the producing zones and any potable water zones if applicable is measured and verified. Choice of whether to use perforating or cavity shots is made. The casing is pressure tested after setting cement retainers. The different equipment required for the job is determined and assembled. Estimate of abandonment/re-abandonment costs is made. In contrast, the steps followed for the Hutton tension-leg platform (TLP) in the East Shetland Basin of the North Sea involved three phases [13]: Perform standalone wireline intervention. Perform drilling unit intervention to set the cement plugs after the first wireline plug has been set. Cut casing 10 ft below the seabed and recover casing stumps. Another abandonment performed in the North Sea followed a different procedure [14]: A permanent cement primary barrier placed immediately above the reservoir. A secondary barrier placed as a back-up to the first barrier. A third barrier then placed near the surface to isolate shallow water-bearing sands. Severed completion tubing and recover wellhead. In Western Canada, the traditional abandonment procedure of wells with casing vent flows included the following: The source of the casing vent flow is estimated or determined. If the source zone is shallower than the producing zone, the producing zone is abandoned. The source zone is perforated. Depending on the feed rate obtained at the estimated source depth, either a bradenhead or a retainer squeeze is performed. Retrievable tools are used as required. Typically, Class G cement with Calcium Chloride and some fluid-loss control is utilized. The slurry is placed and a static squeeze pressure of 7 MPa is attempted. As needed, cement is drilled out and perforations are tested for seal. Often, several attempts are made in order to obtain a static squeeze pressure of 7 Mpa on surface or mitigate the casing vent flow. Techniques for Abandonment The techniques used for plugging and abandonment of drilled well worldwide are generally based on industry practise. These techniques include; Rig Coil tubing unit Rigless abandonment COIL TUBING UNIT The flexibility of coiled tubing has recently been tailored to develop rigless abandonment [15,16]. This method, focuses on harmonizing all well services to accomplish utmost efficiency. Coiled-tubing unit [fig.] abandonment, like any other method, is more effective when appropriate cementing procedure is used from the kick-off of the well, from original zonal isolation with the primary cement sheath to plugging and abandonment. Early prevention of microannulus can help operators obtain a complete final seal. Five main criteria are recommended for optimal abandonment performance with coiled tubing: Mobility; All equipment should be mounted on wheels for increased mobility. Self-sufficiency; the service company provides nearly all activities. Dry location; Fluids are not drained on or near the wellsite. Single operation; the job is completed in one visit to the wellsite. Low mileage; Move time is reduced and transport optimized for maximum efficiency in unit and camp moves. In this abandonment technique geological consideration like the type and condition of the reservoir and caprock formations are take into account. Permanent seals typically must be made between producing zones and at impermeable caprock formations. The condition and configuration of cement, perforations, tubulars, and downhole equipment are also considered. In addition to providing complete, permanent seals, the use of coiled-tubing can help increase abandonment efficiency. This method can provide the following advantages: Increased tripping speeds Increased rig-move efficiency Precise placement of cement plugs; exact spotting of plugs at the interval of interest even in deep well as coil tubing can be reciprocated while pumping. Suitable for use on live wells; it is possible to run CTU for remedial cement squeeze in live well as the wellbore can be controlled using the BOP and stripper assembly. No need to pull production tubing; existing tubing and wellheads do not have to be removed to access the producing interval. Success using the coil tubing method has been recorded in Oman. REGULATORY REQUIREMENT FOR ABANDONMENT IN THE NORTHSEA AND USA In the early years on the oil and gas industry, many wells were drilled and some were found to be dry and subsequently were abandoned without much consideration given to the manner in which the wells were abandoned. Sometimes tree stumps were thrown in the well as a means to plug it [3], during this era the preservation of the groundwater, in general, the environment was not a major issue, and there was no defined regulation by the oil states or agencies. During the tail end of the 1930s different states and agencies in the US started establishing regulations, this defined requirement to ensure better well abandonment [D.G Calvert, et al 1994]. The number of regulation guiding well abandonment has risen along with the rising need to protect the environment in countries around the world. Today most countries have some form of regulation that addresses well abandonment requirement; though these regulations are not uniform and differ from country to country and body to body, they provide a minimum standard for operating companies. For instance for the state of California in the United States of America, the different governing bodies have their own regulations which are as follows; Minerals Management Services (MMS): The basic plugging requirements are found in 30 CFR 250.110 Subpart G. Department of Conservation, Division of Oil: Gas, and Geothermal Resources (DOC) The California Code of Regulations Title 14 Division 2, Chapter 4 beginning with Section 1745 focuses on the fundamental plugging requirements. California State Lands Commission (CSLC): The fundamental plugging requirements in the California Code of Regulations Title 2 Section 2128(q). Abandonment in the North Sea In the North Sea as in US, the regulations differ. The different countries that make up the North Sea have their different governing bodies and subsequently different regulation. The law in the UK, Norway, Denmark and Holland holds the last operator of a well accountable and responsible to pay for all the cost incurred in permanently abandoning the well. It also holds them accountable for any leakage and any clean up that may be required in the event of a leak. Abandonment programs in the Northsea are designed to meet the guidelines for abandonment issued by the operation association or government. For the UK sector of the north sea, abandonment guidelines is issued by the UKOOA, similarly for the Norwegian sector the guidelines are contained in the NORSOK/PTIL D-010 standard and for the Netherlands it is contained in the Dutch Mining
