Multiplex Industry in India

Consulting Industry Overview †¢ †¢ The Indian film industry is the largest film industry in the world in terms of the number of films produced and admissions each year. Revenue for 2004 was estimated at Rs. 59 billion (US$1. 3 billion), which was less than 1% of global film industry revenue and a fraction of the U. S. Film industry revenue, which was US$9. 49 billion in 2003. (Source CII ) Film Industry Revenues 12% 4% 57% 9% 2% 2% 14% Domestic Theatrical Leakages piracy In Cinema Ads Music Satellite / DTH / IPTV DVD / VCD / Overseas Cable Overseas TheatricalNearly 80% of Indian Industry revenues come from Domestic and Overseas Theatrical. On the contrary US Film Industry earns only 35% from box office sales and remaining 65% is derived from other revenue sources This clearly signifies the onset and potential of Multiplexes in the Indian Film Exhibition Sector. Consulting Consulting The Film Exhibition Industry †¢ †¢ The Indian film exhibition sector had revenues of Rs. 34 billion in 2004. (Source:CII) The Film Exhibition Industry can be divided into two segments: – – single and double-screen cinemas and multiplex cinemas, i. e. hree screens or more. †¢ As of March 2005, there were approximately 12,000 cinemas in India of which 73 were multiplexes with a total of 276 screens. Multiplexes constitute only 0. 6 % of about 12,000 cinema halls in India, but account for 28% to 34 % of the box office take for the Top 50 films in 2004. (Source Yes Bank) †¢ Consulting The Film Exhibition Industry: Multiplex More than 60 additional multiplexes with more than 220 additional screens are slated to commence operations by the end of 2006, a growth rate of 80-100% Average price of a ticket for a multiplex cinema is Rs. 5 – 85 but the number of screens in multiplexes represented only 2. 3% of total screens in India as of March 2005. (Source:Industry Estimates) An increase in the number of Multiplex screens should result in an i ncrease in film exhibition revenues, so the opening of new Multiplexes represents a significant growth opportunity for the industry.

Least squares

The backbone of analytical methods consists of various mathematical and procedural concepts to represent relations between points in the object, their corresponding images and operational procedures to solve specific problems. Analytical photogrammetric procedures may be considered along three operational stages, each invol ving specific instruments (Fig. 6. 1), viz. , those used for acquisition of image data (mensural), those used for data-processing and analyses (computational) and those used for display or presentation of the results.In view of the above, we would study the historical developments firstly with regard to the concepts and next with regard to the instruments and their potentials for the future. A mathematical model, in expressing the relevant concept, provides insight into the underlying chain of events. There is no mystery about the way in which this insight is achieved. The mathematical models have no scientific value unless they have been validated adequately thro ugh experience and research. Scientific validation is an openended process. As a mathematical model is successfully tested and used, it becomes established.Otherwise it stands to be changed, modified or simply dropped. We have witnessed this through the historical development of analytical photogrammetry. Furthermore, photogrammetry being an applied science, it is the content and not the form of the mathematical statement (language) that matters most. Thus we have noticed that mathematical and operational concepts have been adapted to circumstances without really changing the basic contents. The following sections would highlight the conceptual developments without going into personal . details.Hauck (1883) established the relationship between projective geometry and photogrammetry_ This should be considered to be the most fundamental geometric concept and the basis of most classic analytical photogrammetric developments. Ernst Abbe, the cofounder of the German Zeiss Works in 1871 s tarted intense studies and tests for optical elements on the basis of rigorous mathematical analyses. F. Stolze discovered the principle of the floating mark in 1892 while Carl Pulfrich also of the Zeiss group developed a practicable method of measuring and deriving spatial dimensions from stereo-pholographic images with floating marks.He presented in 1901 the ZeissPulfrich Stereocomparator by supplementing Eduard von Orel's (1877-1941) first prototype Stereoautograph at the 73 rd Conference of Natural Scientists and Physicians held at Hamburg. Separately, a ssimilar stereocomparator was invented in 1901 by Henry G. Fourcade (1865-1948) of South Africa. He presented this at the Philosophical Society of Cape Town. Sebastian Finsterwalder (1862-1951) in a series of publications during 1899 to 1937 established a very sthrong foundation for analytical photogrammetry.In these he brought about the geometric relations which govern resection and intersection as well as relative and absolute orientations. He predicted the future possibility of nadir point triangulation 311 and the applicatian af phatagrammetry to. astrageadetic measurements. He also. farmulated the basic laws af errar prapagatian in lang strip triangulatians. He was prabably the first persan to. use vectar terminalagy in phatagrammetry literature (Finsterwalder 1899, 1932). Eduard Dalezal 1862-1955) af Vienna, Austria pravided great internatianal driving spirit as he became the faunding President af the Internatianal Saciety far Phatagrammetry in 1909. He also. created the Internatianal Archives af phatagrammetry. viz. , the usefulness af auxiliary data and instruments in order to. avoid propagation of systematic errors in strip triangulation and the practical advantage of using wide-angle cameras. Heinrich Wild (1877-1951) presented in 1926 at the Second International Congress at Berlin his modified plotter prototype known as Police Autograph.

Traumatic Brain Injury Essay Example | Topics and Well Written Essays - 250 words

Traumatic Brain Injury - Essay Example The patient may also suffer from cognitive problems where the memory and emotional response are affected. The patient may experience an outburst of emotions that range from lack of interest to overreacting. Diminished impulse control leads enhanced interpersonal problems where coping skills fail to function and may result in depression (Gainer, 2004, p. 43). Traumatic brain injuries require a substantial amount of time in order to recover from it. During this period, the family and society in general are tasked with coping, managing and enduring the stress involved with caring of the affected patient. The society has to bear the behavioral changes associated with the brain injury. Axonal shearing injury occurs due to sudden movement of the brain, which results in tearing of brain tissue. This may cause bruising and swelling, which may add more pressure to the brain itself. It is therefore, necessary to ensure great care when handling the patient so as not to cause any more harm or damage (The patient Education Institute, 2009, p. 3). This is achieved by ensuring that the patient is in a safe environment with minimal agitation. Individuals handling the patient should also ensure that the patient is kept at zero rated stress levels with the assurance that all will be well. In conclusion, traumatic brain injuries are potentially fatal if not diagnosed, managed, and treated in time. It is also critical to ensure that injuries to the torso are not incurred by observing all safety measures. Gainer, R., (2004). Psychritric Issues in Traumatic Brain Injury.

The impacts of EU Policy on Sustainable Energy Essay

The impacts of EU Policy on Sustainable Energy - Essay Example The European Union has recognised the citizens of the member countries need to be responsible and generate a reliable supply of sustainable energy which is also cheaper to afford so that the living standards are maintained. Furthermore the union also advocates for the reduction of the negative effects of the fossil fuels on the climate and the regional environment at large. The EU policies are designed to create a competitive internal energy market that would offer quality and cheaper services. This would mean that there would be enhanced development of renewable energy sources and cut down reliance on imported energy sources. The European Union has targeted to use features that address energy education, conservation of energy, environment resource protection, energy policies, renewable energy, and distribution of energy (Mcgowan & Mansell 1992), dissemination of useful information and maintainability of energy from producers to consumers. The sustainable energy addressed includes solar power, wind power, geothermal power, tidal power, bio-fuels and wave power. Nuclear fission is some times included but it usually presents the risk of disposal problems and peak uranium levels (Haughton & Counsell 2004). The EU has The EU has not been taking the energy conservation as a serious issue until the approval of the European Energy Policy in the year 2005 in London. EU had to come up with a strategy to fund the research to exploit sustainable energy. The seventh frame program (FP7) was formed to finance the research that is underway from 2007 to 2013. The FP7 fell short of the main intention of its formation and is currently also funding Fusion research which will not achieve results on the climate change until beyond the year 2050 (Lovegrove & Dennis 2006). Currently the strategic energy technology plan is in the lead and has put up plans for the EU technology procedure to develop and enhance the use of low carbon energy technologies. Some of the initiatives in the SET plan include the European Wind Initiative where turbine s will be used to generate energy. This is dependable on the daily whether variations though it can be used to provide base load electricity together with tidal wave energy. The European solar Initiative is also another type of energy that is dependent on whether and can be stored in water as heat, thermo-chemicals as ammonia and in rocks (Lovegrove & Dennis 2006). European also works under the carbon dioxide, transport and storage initiative to address the requirements of safe production of the energy implying that there should be zero emission, the sustainable nuclear fission is very important and has been put under way so that the generation of the type IV reactors are achieved. Energy Research The European Union has established an energy research alliance to facilitate the capabilities of the EU energy research which would achieve world class performance thorough sharing of the global facilities. This strategy will be the major driving force to achieve low carbon technologies and help reduce global warming. The research alliance is the chief player in development of the new energies to ensure that European Union achieves the low carbon

Christian denomination Research Paper Example | Topics and Well Written Essays - 1250 words

Christian denomination - Research Paper Example Though the denominations have a similar origin and are all followers of Christ, their variations arise from their differing views about the bible and its interpretations. A major factor connecting the denominations is the fact that they all rely upon the Bible for guidance, though there may be variations in these Bibles. As such, an example of a Christian denomination is the Jehovah Witnesses that started in the late 1800’s. Charles Taze Russell, who was a child to Joseph and Anna Russell, started this denomination while under bible study class at 18. During his bible studies, he interpreted the bible and came up with the conclusion that there was no such thing as the Holy Trinity and, on this, he started organizing himself to mobilize others who shared similar ideas. Moreover, he broke away from his then church as his views differed with what was spread by his church. Apart from this, he was also of the idea that hell fire was nonexistent and did not buy the idea that Christ was a deity. In the course of popularizing his ideas, he started publishing magazines and journals mostly countering other denominations, and by 1884, after gaining much foot, he came up with The Watchtower and established Watch Tower Tract Society that later transformed into the present Watch Tower Bible and Tract Society (Butalia 123). This assisted in the denominations publications that were mainly biased upon Russell’s ideas, as he was the sole author, and his main motive was to make his ideas known. Moreover, he organized denominational congregations where the followers received continuous teachings and Bible interpretations. This went on until his death in 1916. Upon Russell’s death, the society, which was then under the name International Bible Students Association due to its composition of bible study students, was taken over by Joseph Franklin. Joseph had the eccentricity of Russell, and he too made various controversial decisions while reigning at the society . This led to further split in the society but Joseph was unrelenting in his thoughts. Despite this, he retained the majority of followers. In light of this, in 1931, he changed its name to Jehovah’s Witnesses, a name that stuck to date. After the passing on of Joseph, the society went under the leadership of various personalities such as Nathan Knorr and William Franz in the course of its transformational journey (Butalia 145). Nathan was accredited with commissioning a new Bible translation and incorporating policies that enabled for continued growth worldwide. Others who have graced the management of the society include Milton Herschel and Don Adams, through which the denomination has grown in leaps and bounds, transforming under each individual leadership. The early and founding leadership of the society was well known for their penchant for coming up with chronologies that tried to predict the dates that the world would end. After a series of uneventful episodes and disa ppointments, the society abandoned the culture of trying to figure out the end of the world. Jehovah’s Witnesses are involved in a variety of practices that set them apart from the rest of the denominations. Their main practice is evangelism, which they mainly carry out on a door-to-door basis. Their principles are based upon their interpretation of the Bible, which at times differ from other Christians. A main point of divergence between Jehovah’s Witnesses and other Christians is their denial of the holy trinity and view that hell is nonexistent. They are not

Risk – Given that the Majority of Takeovers Destroy Shareholder Value, What Are the Major Risks? 11 Conclusion 13 References 14 Introduction Evidences reveal that M&As can be quite risky to lead the pathway of the acquiring company’s destruction and on the other hand, be highly beneficial to assist the company in the attainment of its long-term objectives. Despite the immense risk, companies opt for M&As in order to gain the benefits of operational leap, integration, larger customer base, channels and higher competencies (Galpin & Herdon, 2007). One of the most risky acquisitions in the recent past can be identified as the acquisition of National Westminster Bank (NatWest) by the Royal Bank of Scotland (RBS) in the year 2000. It is recorded as one of the most daring acquisitions, due to the fact that during the period of acquiring NatWest, RBS was recognised to be smaller than the target company. It took a great effort from RBS’s e nd to complete the deal and rewarded it the reputation of one of the leaders in the British Banking Industry (Larsen, 2007). With this concern, the paper will examine the entire process of acquisition considering the various aspects, such as strategic fitness of NatWest, regulatory factors influencing the process, justification of the valuation of acquisition, defence tactics applied, implementation of integration and risks involved in the acquisition. 1. Strategy – How Does The Target Company Appear To Fit into the Acquirer’s Long-Term Strategy? According to the experts, strategic fitness of the target company in M&A is considered to be one of the most significant aspects while determining the plan. Because, underneath every M&A the observed motive of the acquiring company or the merging companies are to increase the value of the two companies together which would be more than the sum of the total values of both the companies. Strategic fit of the target company, thus , holds a significant position to increase the overall value of the acquirer (Lee & Pennings, 1996). The strategic fit of the acquisition and the target company can be analysed in depth considering the fact that M&As are often termed as a past of the strategic objective of the acquirer to attain growth and higher competency (Edinburgh Business School, 2008). The objective can be well identified in the acquisition of NatWest by RBS. It was a horizontal acquisition, which means that the target company and the acquirer belonged to similar product line and also to a similar cultural background. This reduced the constraints in terms of cultural divergences. The prime objective of the acquisition depended on the fact that RBS was facing major difficulties in terms of shrinking stock prices to approx 32% and required growth. Similarly, with an increased competition and reducing market share led by the falling stock price and increased operational costs; NatWest opted to go for an M&A in or der to survive in the industry (Mahar & Polson, 2003). Being three times larger than RBS, NatWest was able to reward a higher market share and increased balance sheet value quite instantly after the acquisition with a paid bid of ?21 billion (NatWest, n.d). Subsequently, the stock price of RBS increased rapidly over the next two years (Mahar & Polson, 2003). Therefore, it is quite apparent that the acquisition proved to be a successful one in the short-term as well as in the long-term perspective. The market

The Flow of Foreign Direct Investment to Developing Countries Essay

The Flow of Foreign Direct Investment to Developing Countries - Essay Example This theory draws heavily on the more general work of Williamson that explores the conditions under which firms choose a hierarchical approach to engaging in business activities rather than a market-based approach. Williamson argues that where two sets of conditions exist, firms will tend to prefer internal or hierarchical approaches. These conditions include oligopolistic (few sellers) or oligopsonistic (few buyers) market settings and situations of great uncertainty. Oligopolistic or oligopsonistic situations lead to the choice of a hierarchical approach because, in these situations, opportunistic economic agents will make it very difficult for a firm to negotiate an equitable transaction. In situations of uncertainty, the fact that individuals and organizations are limited in their analytical capacity will lead to internal organization because of the difficulty of writing and enforcing long-term contracts that incorporate all the necessary contingencies that arise as a result of a n uncertain environment (Michael, 1982). Building upon this work, international business theorists suggest that firms that venture overseas either have a particular competitive advantage or seek a competitive advantage. A firm's existing competitive advantage might be its superior technology, its unparalleled management expertise, or its unique brand name. Indeed, these competitive advantages are often intangible assets. Though critical to the firm, they are not identified as fixed assets in the firm's balance sheet. The firm has various options it could use to benefit from these competitive advantages. These options span the choice of a market or a hierarchical approach. In particular, the firm could sell or rent these advantages on the... This essay stresses that the worldwide pool of labor expanded beyond the borders of the countries with enfranchised working classes and high levels of reproduction. Employers seeking to minimize their direct employment costs and their indirect political burdens sought out communities of workers who were politically less potent than those in the older industrial states and whose costs of reproduction were lower. This paper makes a conclusion that the findings highlight the interaction between global financial institutions and local political-economic variables. When these variables measure both international and intranational processes simultaneously, they reflect or point to highly interdependent processes that influence the location of foreign investment. In other words, national and international dynamics are so interpenetrating in the modern world system that any analysis that disregards the effect of either set of factors is seriously deficient. As such, the work extends the political sociology of foreign direct investment by showing the importance of international financial institutions in directing and attracting foreign direct investment. Specifically, International Monetary Fund conditionality is both a signal of approval and a generator of policies that create access to foreign investors. When these two factors interact with policies of repressive regimes, foreign investors have re alized their goal: economic access and political protection.

Middleby Corp Essay Example | Topics and Well Written Essays - 1750 words

Middleby Corp - Essay Example Finally, the report includes a personal recommendation from the author, and a hypothetical recommendation from the owner of the Dallas Mavericks Basketball Club, Mark Cuban. Real GDP is forecast to contract by 2.6% in 2009 as the financial crisis and the housing downturn take their toll on domestic demand. Massive fiscal and monetary stimulus will lead to a recovery of growth to 1.4% in 2010. Average consumer price inflation is set to turn negative in 2009 as a result of declining commodity prices. Inflation should turn positive again in 2010, but will remain low owing to the massive slack in the economy. The Feds forecasts show that its staff now expects the unemployment rate to rise to between 9.2% and 9.6% this year. The central bank had forecast in January that the jobless rate would be in a range of 8.5% to 8.8%, but the unemployment rate topped that in April, hitting 8.9%. I believe the stock market will recover to pre-crash numbers by April of 2010. From there, prices should remain stable because investors will still be a little skeptical, and then rise at about 15% for three years to follow. Discussion: The results seem to indicate that Middleby Corporation’s financial progression is well directed into the future; yet, it’s also clear that if a stock purchase is not made in the immediate future it could soon become overvalued. These finds, supplemented by the previous report, constitute substantial analytical information. The information demonstrates to a reasonable level that the company will continue its positive growth for the following five years. For current and prospective investors, the historical data demonstrates that the stock will increase at a minimal level. In regards to the market forecast and contemporary economic trends, my recommendation is to retain the stock. The company seems to have a strong foundation and will continue to grow. The industry is thriving, and the company is excelling

The New Liberalism Essay Example | Topics and Well Written Essays - 1000 words

The New Liberalism - Essay Example The time bracket, from ‘1880s to 1920s constitutes a relatively cohesive era of extensive industrialization and mass enfranchisement’ (Alexander et all.1995). It is also stressed that (Pluralist assertion) Socio-economic development is a precondition rather then the result of welfare state reforms, thus defining â€Å"development as a process of social differentiation and empowerment that generates social needs and fiscal as well as other state resources as well as political demands for provision of income security† ( Wilensky and Lebeaux.1958; Williamson and Pampel.1993). It means that development precedes the demand for welfare state which is accordingly fulfilled in the form of policy response seeking new patterns of redistribution. On the other hand the development of welfare state has been also attributed to the increase in (organic) State’s ‘specialized capabilities to steer’ and chanalize the stresses it experiences during the process of modernization (Skowronek.1982; Skocpol.1992). The Marxists argue that ‘capitalist development is the source which changes class forces and their balance of power’ (Rueschemeyer, Stephens and Stephens. 1991). This means that capitalism through welfare policies redirect and redistribute the power of class forces and tries to assimilate the classes creating new elite in its own reflection. It is however argued that a singular theoretical approach does not fulfill our requirement to determine the dynamics and contours of development of welfare state in UK at the turn of the century.

Government Intervention Essay Example for Free

Government Intervention Essay The American government is practically in our everyday lives, including our private lives. The government is basically everything we do. It is the way we work, the reason why we look for a career, the way we eat or drink to conclude, the way we live. Sometimes it is a problem for most citizens but some other times, it is the real reason why they live better and maintain everything they have. The government is the people; it is education, entertainment, peace but can be completely different at certain periods of time. As a prevention from too much government intervention, the people of America have a representative dating since 1773,called the Tea Party Movement. This movement wants the government to stick to the real meaning and intent of the United States Constitution, meaning that the government should not use such law as the Elastic clause. The Tea Party Movement would also like to see the government reducing its speding, lower taxes and reducing the national debt and federal budget deficit. This means in one phrase, relief to the people. And yet, doing so would require more government intervention in our lives. The Tea Party is like the real representative of the people, because it would like to see the government accomplishing everything the people request, which is mostly impossible because to maintain the law, the government has to follow the Constitution. Yet again, some of the government’s interventions are necessary for us, like the famous healthcare and health insurances, the social securities, the military and even the food we eat. The Party thinks we should be left alone to use, organize and regulate our businesses, schools and other utilities. Therefore taking care of our own taxes and national debt. The Party thinks that the government goes too far with the taxation, national spending, and maintenance of public facilities. But surprisingly, it doesn’t disagree with the government totally. It is against the Abortion law in most Sates along with the government. It believes that no fetus should be removed prior to labor term and even if there is a situation of rape-pregnancy, it still believes that the victim hould carry the fetus until the end of the term. But for mostly everything else, the Tea Party Movement and the government still disagree with each other. The Tea Party Movement members believe that the government intervenes too much in the people’s business but yet, not intervening would probably hurt them and they would get mad at the government. 1) â€Å"In reading your article about the Tea Party movement, it is difficult to determine where the party stands on issues. Its members seem to want a strong military, but don’t want to finance it; they don’t like social programs like Medicare, but readily accept their Medicare benefits; they don’t like the federal bailout of our financial markets, but would be angry if the government did nothing and their investments and retirements went down the drain; they want strong border controls, but again don’t want to pay for it. Their thinking is chaotic and dangerous because if we do what they want they are going to be unhappy with the consequences. They are a mass of contradictions. Which explains in one simple sentence that, sometimes the Party exaggerates about what they want or not. The government’s intervention, seen from my point of view is highly necessary for us living under its control. And when I say â€Å"necessary†, I mean in some fields. Let’s state for example, sanitation. The citizens themselves can not really maintain a clean city, therefore we would need the government’s assistance but sometimes, the city governments probably think that they have bigger fish to fry instead of cleaning the streets. Lately, we have been seeing the streets so covered with snow, that they become ice right there. Why? Just because our representative decided that there were too many jobs out there so he cut all of these jobs where people would have to clean the streets from the imprisoning snow. This is a fact of minor intervention in a field where it is necessary. The government should be more active in that field because when it does not give the citizens that kind of help which is necessary to them, it mostly turns against them. As a result of the snow accumulation, you will have accidents, lateness, and people will get a bad perspective of the government. A quick and easy solution would only consist of creating fast and easy jobs where you would have people responsible of cleaning the streets from the snow and would also be very useful to their community and state. This field requires government’s intervention but sometimes, the citizens might pass of its need and you can always have the garbage ollectors to do that but it still is not their responsibility. The next field requires more government intervention than that last one except that it is mostly better taken care of. Nowadays, education is very important. And it has very expanded from how it was two decades ago. This is what Milton Friedman has to say about the government’s intervention in this field and its successful results. 2) â€Å"Education is today largely paid for and almost entirely administered by governmental bodies or non-profit institutions. This situation has developed gradually and is now taken so much for granted that little explicit attention is any longer directed to the reasons for the special treatment of education even in countries that are predominantly free enterprise in organization and philosophy. The result has been an indiscriminate extension of governmental responsibility. † These intelligent details about the new education system explains how education is getting easier to access and how the government plays a big role in its development. Education is so important and necessary that it is mostly paid for by the government itself. Which explains that the government’s intervention in this field is both very necessary and satisfied. From kindergarten to senior year in high school, the government pays millions for one’s education and after that, depending on your parents’ financial status, they will help you pay for college or even pay it for you. This is an example of when the government’s intervention is necessary and satisfying. The government’s intervention is enough in this field because it helps people to get an education which is going to be useful to both the country and the individual. By doing so, the American government gets a better perspective from foreigners and from its own citizens. This kind of resource will always be useful to the country. I believe the government should intervene more in the sanitation field, given the fact that the citizens can not accomplish some actions by themselves. I believe the government should have more workers in the sanitation field because it is necessary to have people cleaning the streets. By doing so, it would be a great advantage for both the state government and its citizens. Reducing by doing so, the multiple incidents and disagreements that would have happen if there were nobody to clean the streets and make it easier for people to circulate in the city. That would give more people an opportunity to pay their bills, put bread on their table, and stay out of trouble also. I think that the government’s intervention in the education field is great, not too much not too less. I am grateful to the fact that the government has to pay for my education given the fact that I would not be capable to pay for it myself. The government pays for education, feed the students and even give them a warm place to be in all day. I personally do not see what else the government could do for its students while giving them this great opportunity of learning something that can be useful for them later in life and giving them a way to put money in their pocket. The government intervention is great in this field and I think it should maintain the status quo until they find a better way to improve the way they educate and instruct the American population, which is by the way very weak compared to some poor countries.

Nurse Staffing: Job Satisfaction and Retention

Nurse Staffing: Job Satisfaction and Retention Elizabeth Campins Overview of Quantitative Article The study conducted by (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014), entitled Nurse Staffing and the Relationship to Job Satisfaction and retention, will be the object of the article analysis for this assignment. We are going to evaluate the research question of the study, the study design, representativeness, and the result of the data analysis including strengths and weakness of the study. Research Question The problem that has been addressed in the study is if the nurse-patient ratios affect job satisfaction and retention. The research questions for this article are the following: Has the number of patients assigned to the nurse resulted in job satisfaction? Has the actual economic situation influenced nurse decision to stay in the current position? (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014) The above research questions contain variables referred as predictors that can be measure. Those predictors are the staffing size of registered nurses, and number of the patients assigned to nurses. For the second research question the predictor is the actual economic situation which includes the numbers of layoffs and/or hiring, and costs-services reduction. The outcome of this study is nurse retention and job satisfaction. One we have the problem clear, the population of interest identifies, the interventions considered feasible, and the standard and future comparison established we are in the path to find the best evidence (Adams, 2012, p. 73). Study Design Nurse Staffing and the Relationship to Job Satisfaction and retention by (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014) is a quantitative design study. It is valuable for explaining relationship, nursing measurement and quantification that conduct to conclusive results (Peters, 2012, p. 161). The specific design of this study is non-experimental. It describes the relationship between nurse staffing, job satisfaction, and nurse retention in an acute care environment. More specifically this article is a correlational design study because establish relationship among variables or better to say among predictors and outcomes (Peters, 2012, p. 176). The type of predictive correlational designs for this study is model-testing. For this model type it is probable that researchers hypothesize which variables can conduct to better outcomes. Sample Size and Representativeness The type of sample for this study is a non-probability sampling method. It is used when the sampling frame cannot be calculated. As a result, the threat of selection bias is increased and is less representative of the selected population (White, 2012, p.257). Among non-probability sampling, this article is a convenience or consecutive type where the participants are recruited as they become available (White, 2012, p.257). There were seventy subjects selected as they become available. The majority were female with ages between thirty three and forty five years old. In addition, data collection last over thirty days. The strategy for choosing the subjects were stablished before the selection. It requires RN licensed, with six months experience at bedside in an acute care institution. The level of education at the time of the collection, age, gender, was also required. In addition was asked if the subjects were employed in a Magnet hospital. Results of data analysis Procedures Quantitative method takes in consideration data analysis after the data collection is finished. The study used statistical analysis. The tool was IBM Statistical Package for Social Science (SPSS), version 20. For demographic and subscale variable was used descriptive statistics to determine if the predictive variable, that we mention at the beginning of the paper were related to the outcome nurse retention and job satisfaction. The following survey tools NWI-R (Nursing Work Index Revision) and COP (control over practice) subscales, which was taken from the NWI-R, were used to measure job satisfaction. A weak positive relationship between control over practice and nursing staff indicates that there is a relationship between workload and job satisfaction. One more retention variable was analyzed with frequency and percentage to get results about the actual economic situation affecting the decision to keep the current position. A moderately strong negative correlation shows that a nurse will consider leaving their actual position if the dissatisfaction increases. It Level (p) means a statistical parameter of the analysis. It was set at alpha equal to 0.05. The theme identified was nurse-patient high ratios work-load. It concluded that incrementing responsibilities during the shift put at risk satisfactory patient care, and raise nursing dissatisfaction and turnover. A common strategy mentioned for the participants to retain them in bedside nursing care was improving nursing-ratios. This strategy will decrease the cost of hiring and training new staff nurses, and it will retain experienced nurses. Improving the nurse to patient ratio is highly valuable to increase job satisfaction and retention. Summary of the Strengths and weakness The study major strengths were in data collection. The method of collection corresponds directly with the research question. It contains a variety of age groups and level of experience of the participants. An additional strength of the study is the use of control over practice subscale (COP) as an important survey mechanism to measure job determine the levels of job satisfaction and its impact on the nurse environment (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014). The main weakness in the study was a sample size with only seventy participants as they become available during a thirty days period. For this reason is complicated to determine the generalizability of this research to the larger population (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014). The study demonstrates that exist relationship between predictors and outcomes. This relationship does not show relevant threats in bias, history, maturation, testing or instrumentation. We are confident that the study has a relevant internal validity. On the other hand, it is not possible to conclude that the study can be generalized to other subjects or settings because of the limitations of the sample size (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014). This study is not generalized to larger population, as a result, has a weak external validity. Summary of the Major Points of the Paper From Nurse Staffing and the Relationship to Job Satisfaction and retention by (Hairr, Salisbury, Jonansson, Redfern-Vance, 2014) we considered two important research questions for a quantitative study. It was reviewed the sample size and its representativeness of the population. After analyzing the data and procedures results we summarize the strengths and weakness of this study supporting our conclusion with (Peters, 2012, p. 150). Overview of a Qualitative Article The study conducted by (Lavoie-Tremblay et al., 2014), entitled Transforming care at the Bedside: Managers’ and Health Care Providers’ Perception of their Change Capabilities will be the focus of the article analysis for this assignment. We are going to evaluate the research question of the study, the study design, representativeness, and the result of the data analysis including strengths and weakness of the study. Research Question The problem that has been addressed in this study is the perceptions of managers and others healthcare providers about their change capabilities. The research questions are the following: Are the new strategies, that nurses are implementing, working to create better results in a way that make communication and teamwork easier and more efficient? Does the new project reduce wasteful work? (Lavoie-Tremblay et al., 2014). In the above research questions the research has interest in specific information from the person point of view and their inside about the subject studied (Mauk, 2012, p. 189). Participants that are knowledgeable on the researching theme are called key informants for the purpose of qualitative research. Study Design Transforming care at the Bedside: Managers’ and Health Care Providers’ Perception of their Change Capabilities by (Lavoie-Tremblay et al., 2014), is a qualitative design study. Among of the four types of qualitative research, our study is categorized as grounded theory where the main review of literature is examined when the research has being completed to compare the theory with other reviews, and create theories for other processes (Mauk, 2012, p. 199). There is not set of sample size at the beginning of the data collection. The researcher gets data until they are saturated with the information needed (Mauk, 2012, p. 200). The strategy used in our study is focus groups. The study involved three focus groups: pediatric medicine unit, an adult acute respiratory care unit, and an adult neurologic unit. Also was considered three individual interviews. The study was conducted for nine months (Lavoie-Tremblay et al., 2014). Sample Size and Representativeness As stated before, sample size in grounded theory is known at the end of the collection data. It relied on focus groups where the key informants where selected from managers and healthcare providers included in the transforming care at the bedside (TCAB) teams. It also includes recruited patient’s representation from the hospital’s committees whose members had been patients or had family members who were patient. The sample included sixteen women and three men for a total of nineteen participants. The demographic information (gender, age, education, job title) was collected to allow for an external assessment of the generalizability of the findings to a different setting (Polit Beck, 2012, p. 518). Results of data analysis Procedures Interviews were audio-recorded and transcribed using NVivo data analysis. This procedure facilitates a rigorous analysis of unstructured data (Miles, Huberman, Saldaà ±a, 2013). Data analysis was examined in three ways: Condensing the data or coding the transcripts, presenting the data for discussion with the research team, and verifying the data with an audit trail to keep a record of the data collection details throughout the study. Two outside researchers coded the transcripts to reduce the chances of biased interpretation. Some of the themes identified were: Learning skills, sharing leadership capabilities with other staff members, impact of the changes for the institution and personally, the perception of the team approach to lead change, among others. Summary of the Strengths and weakness The strengths of the research article were sustained in the fact that the motivation to work as a team develops change capabilities in participants. The study gave the tools and resources necessary to identify, implement and evaluate changes. The study was successful in developing most of the target elements to change. Participants mentioned how their unit’s mode of functioning went from working alone to teamwork style. Also, they mentioned that the TCAB project helped them develop new skills and capacities for change. This study has credibility (Mauk, 2012, p. 200). It has being confirmed through members check after researchers sharing the results with participants to make sure the finding reflected what they say during the interviews. The study limits the generalizability of the results because was only conducted in three units. Summary of the Main Points of the Paper Transforming care at the Bedside: Managers’ and Health Care Providers’ Perception of their Change Capabilities by (Lavoie-Tremblay et al., 2014) we considered two important research questions for a qualitative study. It was reviewed the sample size and its representativeness of the population. After analyzing the data and procedures results we summarize the strengths and weakness of this study supporting our conclusion with (Mauk, 2012, p. 194). References Adams, S. (2012).

Procedures For Drill String Design Engineering Essay

Procedures For Drill String Design Engineering Essay This chapter presents general procedures for drill string design. The design aspects of critical importance and factors controlling drill pipe selection are highlighted. The term Drill Stem is used to refer to the combination of tubulars and accessories that serve as a connection between the rig and the drill bit (RGU lecture slides). It consists mainly of Drill Pipe, Drill Collars (DC) and Heavy Weight Drill Pipes (HWDP) and accessories including bit subs, top drive subs, stabilisers, jars, reamers etc. Drill stem is often used interchangeably with the term Drill String which actually refers to the joints of drill pipe in the drill stem. For the purpose of this report, Drill String will be used to refer to the string of drill pipes that together with drill collars and heavy weight drill pipe make up the drill stem see fig 3.1. 3.1 DRILL STEM COMPONENT DESCRIPTION 3.1.1 Drill Pipe The drill pipes are seamless pipes usually made from different steel grades to different diameters, weights and lengths. They are used to transfer rotary torque and drilling fluid from the rig to the bottom hole assembly (drill collars plus accessories) and drill bit. Each drill pipe is referred to as a joint, with each joint consisting of a pipe body and two connections (see fig 3.2). Drill pipe lengths vary, and these different lengths are classified as ranges, the available or more common ranges include: Range 1: 18 22 ft Range 2: 27 30ft Range 3: 38 40ft. Drill Stem. Fig 3.1: Drill Stem with components. (Heriott Watt University lecture Notes: Drilling Engineering) Drill pipes are also manufactured in different sizes and weights which reflects the wall thickness of the drill pipe. Some common sizes and their corresponding weights include 31/2 in. 13.30 lb/ft and 4 1/2in. 16.60 lb/ft. The indicated weight is the nominal weight in air (pipe body weight excluding tool joints) of the drill pipe. A complete listing of API recognised drill pipe sizes, weight and grades are published in the API RP 7G. The drill pipe grade is an indication of the minimum yield strength of the drill pipe which controls the burst, collapse and tensile load capacity of the drill pipe. The common drill pipe grades are presented in the table below Grade Yield Strength, psi Letter Designation Alternate Designation D D-55 55,000 E E-75 75,000 X X-95 95,000 G G-105 105,000 S S-135 135,000 Table 3.1: Drill Pipe Grades. Drill pipes are often used to drill more than one well, therefore in most cases the drill pipe would be in a worn condition resulting in its wall thickness being less than it was when the drill pipe was brand new. In order to identify and differentiate drill pipes, they are grouped into classes. The different classes are an indication of the degree of wear on the wall thickness of the drill pipe. The classes can be summarised as follows according to API standards: New: Never been used, with wall thickness when to 12.5% below nominal. Premium: Uniform wear with minimum wall thickness of 80%. Class 2: Allows drill pipe with a minimum wall thickness of 70%. It is essential that the drill pipe class be identified in drill pipe use or design, since the extent of wear affects the drill pipe properties and strength. When specifying a particular joint of drill pipe, the class, grade, size, weight and range have to be identified, the specification could therefore appear thus: 5 19.5 lb/ft Grade S Range 2 Fig 3.2: Parts of Drill pipe. (Handbook for Petroleum and Natural gas) 3.1.2 Tool Joints Tools joints are screw type connections welded at the ends of each joint of a drillpipe. The tool joints have coarse tapered threads and sealing shoulders designed to withstand the weight of the drill string when it is suspended in the slips. Tool joints are of two kinds; the pin (male section) and the box (female section). Each drill pipe has a pin attached to one end and a box attached at the other end. This makes it possible for the pin of one joint of drill pipe to be stabbed into box of a previous drill pipe. There are several kinds of tool joints widely used: Joint Type Diagram Description Internal Upset (IU) Tool joint is less than the pipe. Tool joint OD is approximately the same as the pipe. Internal Flush (IF) Tool joints ID is approximately the same as the pipe. The OD is upset. Internal / External Upset (IEU) Tool joint is larger than the pipe such that the tool joint ID is less than the drill pipe. The tool joint OD is larger than the drill pipe. Table 3.2 Types of tool joints. (The Robert Gordon University Lecture Notes: Drill String Design) 3.1.3 Drill Collars Drill collars are thick walled tubes made from steel. They are normally the predominant part of the bottom hole assembly (BHA) which provides Weight on Bit (WOB). Due to the large wall thickness of the drill collars, the connection threads could be machined directly to the body of the tube, thereby eliminating the need for tool joints (see fig 3.3). Drill collars are manufactured in different sizes and shapes including round, square, triangular and spiral grooved. The slick and spiral grooved drill collars are the most common shapes used currently in the industry. There are drill collars made from non-magnetic steel used to isolate directional survey instruments from magnetic interference arising from other drill stem components. The steel grade used in the manufacture of drill collars can be much lower than those used in drill pipes since they are thick walled. Functions Provide weight on bit Provide stiffness for BHA to maintain directional control and minimise bit stability problems. Provide strength to function in compression and prevent buckling of drill pipes. Fig 3.3: Carbon Steel Drill Pipes. 3.1.4 Heavy Weight Drill Pipe Heavy weight drill pipes (HWDP) are often manufactured by machining down drill collars See fig 3.4. They usually have greater wall thickness than regular drill pipe. HWDP are used to provide a gradual cross over when making transition between drill collars and drill pipes to minimise stress concentration at the base of the drill pipe. These stress concentrations often result from: Difference in stiffness due to the difference in cross-sectional area between the drill collar and drill pipe. Bit bouncing arising from rotation and cutting action of the bit. HWDP can be used in either compressive or tensile service. In vertical wellbores it is used for transition and in highly deviated wells, it used in compression to provide weight on bit. Fig 3.4: Heavy Weight Drill Pipe. (Heriott Watt University lecture Notes: Drilling Engineering) 3.1.5 Accessories Drill Stem accessories include: Stabilisers: these are made of a length of pipe with blades on the external surface. The blades are spiral or straight, fixed or mounted on rubber sleeves to allow the drill string rotate inside. Functions of the stabiliser include: Stabilise the drill collars to reduce buckling and bending Ensure uniform loading of tricone bits to reduce wobbling and increase bit life. To provide necessary wall contact and stiffness behind the bit to induce positive side force to build angle when drilling deviated wells. Reamers: used in the BHA to enlarge the well bore diameter and ream out doglegs, key seats, ledges. Drilling Jars: incorporated in the BHA to deliver a sharp blow and assist in freeing the drill string should it become stuck. 3.2 DRILL STRING DESIGN The drill string design is carried out in order to establish the most efficient combination of drill pipe size, weight, and grades to fulfil the drilling objectives of any particular hole section at the lowest cost within acceptable safety standards. In order to design a drill string to be used in a particular hole section, the following parameters need to be established: Hole section depth Hole section size Expected mud weight Desired safety factors in tension and overpull. Desired safety factor in collapse Length of drill collars required to provide desired WOB including OD, ID and weight per foot. Drill pipe sizes and inspection class The drill string design has to meet the following requirement: The working loads (tension, collapse, burst) on the drill string must not exceed the rated load capacity of each of the drill pipes. The drill collars should be of sufficient length to provide all required WOB to prevent buckling loads on the drill pipe. The drill pipes used have to ensure the availability of sufficient fluid flow rate at the drill bit for hole cleaning and good rate of penetration. 3.2.1 Design Safety Factors Design safety factors are applied to calculated working loads to account for any unexpected service load on the drill string. They are used to represent any features that are not considered in the load calculations e.g. temperature and corrosion, thus ensuring that service loads do not exceed the load capacity of the drill pipe. Design safety factor values are often selected based on experience from operating within a particular area, the extent of uncertainty in the operating conditions e.g. when operating in HPHT conditions, a larger safety factor is applied than when operating in less harsh conditions. Some commonly used design safety values are illustrated in the table below Load Design Safety Factor Value Tension 1.1 1.3 Margin of overpull (MOP) 50,000 100,000. MOP of 400,000 have been used in ultra deep wells Weight on Bit 1.15 or 85% of available Weight on bit to ensure neutral point is 85% of drill collar string length measures from the bottom (API RP 7G) Torsion 1.0 (based on the lesser of the pipe body or tool joint strength) Collapse 1.1 1.15 Burst 1.2 3.2.2 Drill Collar Selection The drill collars are selected with the aim of ensuring that they provide sufficient WOB without buckling or putting the lower section of the drill string in compression. 3.2.2.1 Size selection Lateral movement of the drill bit is controlled by the diameter of the drill collar directly behind it. Therefore the size/diameter of the drill collar closest to the bit will be dependent on the required effective minimum hole diameter and the relationship can be given as When two BHA components of different cross-sectional areas are to be made up, it is essential that the bending resistance ratio (BRR) be evaluated. This is important because BHA components have tensile and compressive forces acting on them when they are bent in the well bore. These forces cause stress at connections and any location where there is a change in cross-sectional area. Therefore it is important to ensure that these stresses are within acceptable ranges. The bending resistance (BR) of a drill string component is dependent on its section modulus which is given as Z = section modulus, in3 I = second moment of area, in4 OD = outside diameter, in ID = inside diameter, in The BRR is used to express any change in BR and can be calculated using BRR should generally be below 5.5 and in severe drilling conditions, below 3.5. 3.2.2.2 Connections When selecting connections to be used with drill collars, it is essential to check that the BRR of the pin and box indicates a balanced connection. The BRR for drill collar connection is calculated as the section modulus of the box divided by the section modulus of the pin. The API RP 7G contains tables that can be used to determine BRR for any box and pin OD. BRRs of 2.5 have given balanced connections (RGU Lecture notes, 2005). 3.2.2.3 Weight on Bit The maximum weight on bit required is normally a function of the bit size and type. The rule of thumb is: Maximum WOB of 2000lbf per inch of bit diameter when using Polycrsyalline Diamond Compact bits (PDC) and mud motors. Maximum WOB of 5000lbf per inch of bit diameter when using tricone bits. Other factors controlling WOB include inclination, hole size and buckling. In vertical wellbores the length of drill collars required to provide a specified weight on bit is given by LDC = Length of Drill Collars, ft WOB = Weight of Bit, lb DFBHA = Safety factor to keep neutral point in drill collars. WDC = Weight per foot of Drill Collars, lb/ft Kb = Buoyancy Factor. The neutral point as described by (Mian, 1991) referring to Lubinksi, is the point that divides the drill stem into two portions, with the section above the neutral point in tension and that below in compression. Therefore in order to ensure that the entire length of drill pipes remain in tension, the neutral point of the drill stem has to be maintained within the drill collars. According to the API RP 7G, the height of the neutral point measured from the bottom of the drill collars will be 85% of the total length of drill collars used, with 85% being the safety factor. In inclined wellbores, the angle of inclination has to be taken into consideration when calculating the maximum WOB that can be applied without buckling the drill pipe. This is because although the WOB is applied at the inclination of the wellbore, this weight acts vertically, thus reducing the available weight at the bit. Therefore to allow for this reduction, the buoyed weight of the BHA would be reduced by the cosine of the well inclination, thus WOB in inclined holes is calculated with the formula All parameters remain as defined in equation 5; ÃŽÂ ¸ is the angle of inclination of the well. As a result of the vertically acting weight of the BHA, the drill string tends to lie on the low side of the hole and is supported to some extent by the wall of the well bore. Therefore the pipes above the neutral point could only buckle if the compressive forces in the drill string exceed a critical amount. This critical buckling force is calculated as follows Fcrit = critical buckling force, lb ODHWDP = outside diameter of HWDP, in. ODtj = maximum outside diameter of pipe, in. IDHWDP = inside diameter of HWDP, in. Kb = buoyancy factor. Dhole = diameter of hole, in. ÃŽËÅ" = hole inclination, degrees. Since HWDP are sometimes used to apply WOB in inclined wells, and drill pipes are sometimes used in compression, the critical buckling force is calculated for both HWDP and drill pipes. 3.2.3 Drill Pipe Selection Factors to be considered for drill pipe selection include: Maximum allowable working loads in tension, collapse, burst, and torsion. Maximum allowable dogleg severity at any depth in order to avoid fatigue damage in the drill pipe. Combined loads on the drill pipe. The loads considered when selecting drill pipes to be used in the drill string is dependent on the well depth, well bore geometry and hole section objectives. In shallower vertical wells, collapse and tension are of more importance than burst or torsion. Burst is normally not considered in most designs since the worst case for a burst load on the drill pipe would occur when pressuring the drillstring with a blocked bit nozzle, even with this condition, the burst resistance of the drill pipe is likely to be exceeded. Torsion is of less importance in vertical well bores because drag forces are at minimal amounts unlike in highly deviated wells. The dogleg severity of the well for both vertical and deviated wells is important because of increased fatigue in the drill pipe when it is rotated in the curved sections of the wellbore. A graphical method is recommended for drill pipe selection, with the loads plotted on a load versus depth graph. This makes it possible for loads at particular points on the drill string to be easily visualised, and any sections of the drill pipe that do not meet the load requirements are easily identified and redesigned. 3.2.3.1 Collapse Drill pipes are sometimes exposed to external pressures which exceed its internal pressures, thereby inducing a collapse load on the drill pipe. The worst scenario for collapse in a drill pipe is during drill stem tests when they are run completely empty into the wellbore. The collapse loads are highest at the bottom joint of the drill pipes, as a result, the collapse load would normally control the drill pipe grade to be used at the bottom of the drill string. The API specified collapse resistance for different sizes and grades of drill pipe assuming either elastic, plastic or transition collapse depending on their diameter to wall thickness ratio have been calculated and are published in the API RP 7G with the relevant formulae. The maximum collapse pressure on the drill pipe when it is completely empty can be calculated as follows: Pc = collapse pressure, psi MW = mud weight, ppg TVD = true vertical depth at which Pc acts, ft. On some occasions, the mud weight outside the pipe varies from that inside the pipe, also the fluid levels inside and outside the pipe may also vary. This situation could also induce collapse loads. The collapse loads induced by this scenario can be calculated thus L = Fluid depth outside the drill pipe, ft MW = Mud weight outside the drill pipe, ppg Y = fluid depth inside drill pipe, ft MW = Mud weight inside drill pipe, ppg. The value for Pc is then plotted on the collapse load graph as the collapse load line see fig 3.5. It is recommended practice to apply a design safety factor to the collapse load calculated from equations 8 or 9 (depending on expected scenarios) in order to account for unexpected additional loads as wells as unknown variables. The value of the design factor is often between 1.1 1.5 for class 2 drill pipes. According to (Adams, 1985) the design factor should be 1.3 to account for the fact that new drill pipes are often not used for drill stem tests. The value of the collapse load multiplied by the collapse design factor is plotted on the collapse load graph as the design line, this is then used to select an appropriate grade and weight of drill pipe to fulfil these load conditions. Fig 3.5: Sample Collapse load graph. 3.2.3.2 Tension Load The tensile load capacity of the drill string should be evaluated to ensure there is enough tensile strength in the topmost joint of each size, weight, grade and class of to support the weight of the drill string submerged in the wellbore, hence the need to include buoyancy in the calculations. There has to also be enough reserve tensile strength to pull the drill string out of the well if the pipe gets stuck. The stabiliser and bit weight can be neglected when calculating the drillstring weight. In a vertical wellbore, the forces acting on the drill string are tension from its self weight and the hydrostatic pressure from the fluid in the wellbore. The hydrostatic pressure in the wellbore exerts an upward force on the cross sectional area of the drill string, which is commonly referred to as buoyancy. Therefore the resulting tensile load on the drill string attached to drill collars, taking account of buoyancy is calculated as: FTEN = resultant tensile load on drill string, lb LDP = length of drill pipe, ft LDC = length of drill collars, ft WTDP = air weight of drill pipe, lb/ft WTDC = air weight of drill collars, lb/ft MW = Mud weight, ppg. ADC = Cross sectional area of drill collars, in2 FTEN is plotted on the tension load graph as the tensile load line. The tensile strength values for different sizes, grades and inspection classes of drill pipes are contained in the API RP 7G, and can be calculated from the equation: Fyield = minimum tensile strength, lb Ym = specified minimum yield stress, psi A = cross section area, in2 Fyield is plotted as the minimum tensile strength line on the tension load graph. However, these values (Fyield) are theoretical values based on minimum areas, wall thickness and yield strength of the drill pipes. Therefore, these values only give an indication of the stress at which a certain total deformation would occur and not the specific point at which permanent deformation of the material begins. If a pipe is loaded to the minimum tensile strength calculated from equation 11, there is the possibility that some permanent stretch may occur, thereby making it difficult to keep the pipe straight in the wellbore. In order to eliminate the possibility of this occurrence, 90% of the minimum tensile strength as recommended by the API (American Petroleum Institute), should be used as the maximum allowable tensile load on the drill pipe, i.e Fdesign = maximum allowable tensile load 0.9 = a constant relating proportional limit to yield strength. Fdesign is plotted on the tension load graph as the maximum allowable tensile load line. As with the collapse load, a design factor would be applied to the tensile loads to account for dynamic loads in the drill pipe which occur when the slips are set, as well as prevent the occurrence of pipe parting close to the surface. The product of FTEN and the design factor is plotted as the tension design load line in the tension load graph see fig 3.6. Margin Of Overpull A margin for overpull is added to the tension load to ensure there is sufficient tensile strength in the drill pipe when it is pulled in the event of a stuck pipe. This margin is normally 50,000 100,000lb, but in deeper wells margins of overpull have reached 300,000lb. The value obtained after adding the margin of overpull is also plotted on the tension load graph see fig 3.6. The difference between the calculated tensile load at any point in the drillstring (FTEN) and the maximum allowable tension load would also represent the available overpull. This value represents available tensile strength of the drill pipe to withstand any extra forces applied to the drill string when trying to release it from a stuck pipe situation. FTEN and Fa can also be expressed as a safety factor This safety factor is an indication of how much the selected drill pipe will be able to withstand expected service loads. Due to uncertainty with actual service loads and conditions, a safety factor greater than 1 is always required. Slip Crush Slip crushing is generally not a problem if the slips are properly maintained. However, it is necessary to apply a safety factor for slip crushing when designing the drill string. This helps account for the hoop stress (SH) caused by the slips and the tensile stress (ST) caused by the weight of the drill string suspended in the slips. This relationship between SH and ST can be represented by the following equation SH = hoop stress, psi ST = tensile stress, psi D = outside diameter of the pipe, in. K = lateral load factor on slips, Ls = length of slips, in. = slip taper usually 9 ° 27 45 z = arctan ÃŽÂ ¼ ÃŽÂ ¼ = coefficient of friction, (approximately 0.08) The calculated tensile load is multiplied by the slip crush factor () to obtain the equivalent tensile load from slip crushing: Ts = tension from slip crushing, lb TL = tension load in drill string, lb SH / ST = slip crush factor. Ts is also plotted on the tension load graph as the slip crush design line. Fig 3.6: Sample Tension load graph The general step-by-step procedure for drill pipe selection using the graphical method is given as 1. Calculate the expected collapse load on drill pipe and apply the collapse design safety factor to derive the design load. Use the result to select weight and grade of drill pipe that satisfy collapse conditions. Plot expected collapse load and design load on a pressure vs. depth graph. 2. Calculate maximum allowable tensile load for the drill pipe selected in (1) above. Also calculate tension load on the drill string including buoyancy effects. Plot the tension load, specified minimum yield strength, and maximum allowable tensile load values on axial load vs. depth graph. 3. Apply tension design factor, margin of overpull, and slip crush factor to the calculated tension load and plot the individual results on the axial load vs. depth graph. Of the three factors applied to the tension load, the one resulting in the highest value is selected as the worst case for tensile loads. 4. Inspect graph and re-design any sections not meeting the load requirements. When designing a tapered drill string, the maximum length of a particular size, weight, grade and class of drill pipes that can be used to drill the selected hole section with specified WOB can be calculated as: All parameters remain as defined in equation 10 and 11. Note that equation 16 is only used when the MOP design line is the worst case scenario for tensile loads. When slip crushing is the worst case, the formula below is used SF = safety factor for slip crushing. The lightest available drill pipe grade should be used first in order to ensure that that the heavier grades are used upper section of the drill string where tensile loads are the highest. 3.2.4 Dog Leg Severity Fatigue damage is the most common type of drill pipe failure. It is known to be caused by cyclic bending loads induced in a drill pipe when it is rotated in the curved sections of the wellbore. The rotation of the drill pipe in the curved hole sections induce stresses in the outer wall of the drill pipe by stretching it and increasing its tensile loads. Fatigue damage from doglegs tends to occur when the angle exceeds a critical value. This critical value can be calculated as: C = maximum permissible dog leg severity, deg/100ft E = Youngs modulus, psi (30 x 106 for steel, 10.5 X 106 for aluminium) D = Drill pipe outer diameter, in. L = half the distance between tool joints, (180 in, for range 2 pipe) T = tension below the dogleg, lb à Ã†â€™b = maximum permissible bending stress, psi. I = drill pipe second moment of area, = à Ã†â€™b, is calculated from the buoyant tensile stress (à Ã†â€™t) and is dependent on the grade of the pipe. à Ã†â€™t = T/A, where T is defined in equation 19, and A is the cross sectional area of the pipe body in in2. For grade E pipe, The results from equation 20 are valid for à Ã†â€™t values up to 67,000psi. For grade S pipe, The results from equation 21 are valid for à Ã†â€™t values up to 133,400psi. It is recommended that an allowable dogleg severity (DLS) versus depth chart be plotted for every hole section with a particular drill string design since DLS changes with depth. The chart is plotted with the DLS on the x-axis and depth on the y-axis (see fig 3.7). When DLS lies to the left of the line or below the curve, the drill pipe is in safe operating conditions, and when it falls above or to the right of the curve, it is in unsafe conditions. Fig 3.7: Allowable Dogleg Severity Chart. (Mian, 1991) 3.2.5 Torsion Drill pipe torsional yield strength is important when planning deviated wells and ultra deep wells. In deviated wells, increased drag forces acting on the drill string from its interaction with the wellbore increase torsional loads on the drill pipe. In deeper wells, it is important in stuck pipe situations, in order to know the maximum torque that can be applied to the drill string. The pipe body torsional yield strength when subjected to torque alone can be calculated from the equation: Q = minimum torsional yield strength, ft lb J = polar second moment of area, à Ã¢â€š ¬/32 (D4 d4) D = pipe OD in, d = pipe ID in. Ym = minimum yield strength, psi. 3.2.6 Combined Loads On The Drill String Collapse and Tension The collapse resistance of the drill pipe is often reduced when the drill pipe is exposed to both tension and collapse loads. This happens because tensile loads stretch the drill pipe thereby affecting its D/t (diameter -wall thickness ratio) which controls the collapse resistance of the drill pipe. In ultra deep wells, the effect of combined collapse and tension is experienced when function testing the Blow out Preventers (BOP). It is becoming common practice in ultradeep drilling to equip BOPs with test rams in order to enable the BOP be tested without setting plugs in the well head. This is done to save tripping time due to extreme well depths. An example given by (Chatar, 2010), using 65/8in 27.70lb/ft drill pipe showed that with 65/8in drill pipe having 860kips of maximum allowable tensile loads, at half of this load, the drill string is only capable of withstanding 4,500psi collapse loads, which is often not sufficient for ultradeep drilling BOPs. The corrected collapse resistance of drill pipes under tension can be calculated using the formula Where R represents the percentage of the collapse resistance left when the drill pipe is under tension, therefore in equation 25, the value for R is used to multiply the normal plastic collapse resistance of the pipe to give the collapse resistance under tension. R can also be determined graphically with the following steps 1. Calculate Z using equation 24 2. Enter the ellipse for biaxial stress (fig 3.8) on the horizontal axis with the value for Z and draw a vertical line to the ellipse curve. 3. Draw a horizontal line from the vertical line drawn in (2) above to the vertical axis and read off the value. 4. Use the value from (5) above to multiply the collapse resistance to get the corrected collapse resistance with tension. Fig 3.8: Ellipse of Biaxial yield Strength: Effect of tensile loading om collapse resistance. (RGU Lecture notes: Casing design) Combined tension and torsion The torsional yield strength of a drill pipe is significantly reduced when the pipe is under tension loads. The torsional yield strength of the drill pipe under tension can be calculated with the equation Q = minimum torsional yield strength under tension, ft lb J = polar second moment of area. D = pipe OD in, d= pipe ID in. Ym = minimum yield strength, psi P = total load in tension, lb A = cross sectional area, in2 3.2.7 Tool Joint Performance The makeup torque to be applied to the tool joints when connecting drill pipes is calculated as follows ID = inside diameter, in. OD = outside diameter, in. Values for X, M, B and Q for standard connections are presented in the table below Type of Connection X

What Really Counts as Learning :: Russell Thomas Essays

What Really Counts as Learning Learning happens in so many places and in so many ways. Maybe it is at the mall, or at home, or even in a classroom. For Russell Thomas it was in the poor town of Coney Island. In Coney Island, Russell has to learn many hard lessons in life. He learns that you can’t change everything and that life isn’t fair. Russell is forced to realize that failure is part of life and that it happens to all of us. These are all teachings that are irreplaceable and valuable. The lessons that Russell learns are ones that he will use for the rest of his life in his experiences. It is something that you can use on more than just a test for school. That is what real life learning is about and in one way or another we have all experienced it. Russell is the main focus in Darcy Frey’s article about three basketball prodigies from Coney Island. Russell is a tremendous basketball player and hopes to get out of Coney Island on a basketball scholarship. He has the skill to get that scholarship, but even with all that talent he has a major obstacle stopping him. In order to attend college on a scholarship, a score of 700 is required on the SAT. Russell, on his first attempt, only gets a 500; when a 400 is earned just for signing your name. So in order to get that scholarship and 700, Russell dedicates large amounts of time to studying. If he wasn’t working on basketball then he was working on his academics. After all that work Russell never gets his 700, or the scholarship. So therein lies the first lesson that Russell learns; life isn’t fair. Russell tries his hardest to bring up his grades and earn that 700, but when it comes down to it he has grown up in a low class area, without many opportunit ies. Frey described Coney Island as a place where there are â€Å"†¦no stores, no trees, no police; just block after block of gray cement projects†¦Ã¢â‚¬  (Frey 38). Russell had what can hardly be called an education. It is a place where most of the good basketball players with any chance at a scholarship never make it, they either end up dead or back in Coney Island dealing drugs.

My Last Day in California Essay -- Personal Narrative, essay about mys

  My eyes opened very early that morning. I looked out of window and saw beautiful weather outside.   It was cold wind.   The flowers in my garden were smiling at me.   All of a sudden my eyes got watery.   I remembered that this was my last day in California.   I was going to America early the next day morning with my parents and family.   The day was Saturday, 20th December.   Tears were running down my face.   I went downstairs; everybody in the house was sleeping.   They had been packing until late night and I didn't want to them wake them up.   Therefore, I went back upstairs.   I just started thinking about how I was going to leave my house, my friends, my relatives, and my country.   The place where I grew up, the people with whom I had grown up, how I was going to leave without them?   It was going to be very hard for me to leave something that I had used to.   I took out my album and started looking at pictures with my friends and r elatives.   I looked at the life that I had enjoyed with them.   The moments of happiness and sorrow that we had shared together.      Ã‚  Ã‚  Ã‚  Ã‚   The day begins, but it didn't begin as usual. Finally about 10 o'clock in the morning, I went down stairs.   Everybody was awake by that time.   They were busy in their work.   Nobody had time to hear me.   I saw a couple of guests sitting our drawing room so I went back upstairs again.   In a few minutes, the intercom in my room rang and I heard my mom tell me to get ready to go to the temple.   I took a bath and dressed up like a pretty Californian girl.   When I get downstairs, everybody was ready to g... ...The luggage was already in the car then we got in.   As we pulled away, I kept looking at my house as far as I could see it.   All of our friends and relatives were coming to the airport.   We got to the airport.   We were running little bit late.   Therefore, we had to hurry to get our luggage and check in.   No one else could enter the airport but customers so I looked at all of my relatives and friends one last time.   They all were crying.   We had never lived that far from each other.   We boarded the plane, and all I could do was cry.   I made my flight to Ohio.      Ã‚  Ã‚  Ã‚  Ã‚   Leaving my home was the saddest day of my life.   I am in Ohio now, still missing the life I enjoyed in California with my friends and family, still believing there is nothing better than home.
