Case Analysis Float Equipment - 1697 Words

Float equipment are a fundamental aspect of cementing operations, which serves as a foundation for casing equipment. They are commonly used in the lower section of the casing and help reduce the stress applied to the derrick by allowing the casing to be floated into place. According to Weatherford oil and gas service company, â€Å"they guide the casing to total depth, prevent contaminated mud from entering the casing, provide a landing point for casing wiper plugs, reinforce the lower end of the casing string, and ensure greater accuracy of cement slurry displacement†. Floating equipment is typically made up of 2 or 3 important tools, which include a float collar and float shoe or guide shoe. This paper will focus on the mechanisms and†¦show more content†¦Additional functions of cementing include but are not limited to preventing blowouts, sealing of zones of lost circulation, and protecting the casing from corrosion. Drilling in the United States of America dates as far back as 1859, when the Drake well was first drilled in Pennsylvania. At the time one of the most common problems well operators encountered, was their inability to produce oil independently of water. Since there was no casing/casing design, this problem became more prevalent. The water usually came from the same formation bearing the oil, but more commonly it came from an upper sand formation. The implementation of cementing and proper casing design did not start until 1903, when the first cement slurry was used to â€Å"shut off downhole water just above an oil sand in the Lompoc fields in California†(Doherty 1,1960) by mixing and dumping 50 sacks of fine Portland cement by means of the bailer method. After a 28-day waiting period, the cement was then drilled out. It was introduced by Frank .F Hill of Union Company. In 1910, the dump bailer and tubing method was replaced by the two-plug cementing method also known as the P erkins method, which was introduced in California by Almond .A Perkins, and it quickly became the foundation for modern oil well cementing. The cement plugs, were made out of

One quiet day in the 1960’s 3 Des Moines students were wrongly punished for protesting the Vietnam War by wearing black arm bands to school. The school officials believed that the armbands would cause a huge disturbance and be a very big distraction to the student body. The students were then suspended. We will write a custom essay sample on Tinker vs. Des Moines. or any similar topic only for you Order Now The student’s first amendment right had been violated. This right gives us the freedom of expression, to sum it all up, as long as others are not in danger. The staff was quick to punish these students, who were only exercising their rights. I believe that the students that were involved in this case did not deserve to be punished because; in wearing armbands, the petitioners were quiet and passive. They were not disruptive and did not interfere with the rights of others. Therefore, their conduct was within the protection of the Free Speech Clause of the First Amendment and the Due Process Clause of the Fourteenth. Also, â€Å"First Amendment rights are available to teachers and students, subject to application in light of the special characteristics of the school environment. † (http://caselaw. p. findlaw. com/scripts/getcase. pl? court=usvol=393invol=503) Also, I believe that they did not deserve to be punished because; under our Constitution, free speech is not a right that is given only to be so restricted that it exists in principle but not in reality. Freedom of expression would not truly exist if the right could be exercised only in an area that a charitable government has provided as a safe haven for crack pots! The Constitution says that Congress (or anyone else, for that matter) may not deprive anyone the right to free speech. You see, the thing is we properly read it to permit reasonable regulation of speech-connected activities in carefully restricted circumstances. But we do not confine the permissible exercise of First Amendment rights to a telephone booth or the four corners of a pamphlet. Lastly, I believe that students were wrongly treated because; â€Å"The constitutionality of the school authorities’ action was on the ground that it was reasonable in order to prevent disturbance of school discipline. † (258 F. Supp. 971 1966). The court referred to but declined to follow the Fifth Circuit’s holding in a similar case that, the wearing of symbols like the armbands cannot be prohibited unless it â€Å"materially and substantially interferes with the requirements of appropriate discipline in the operation of the school. † (Burnside v. Byars, 1966). In conclusion, The Students in this case were wrongly punished due to the fact that their first amendment right protected their freedom of expression. The pupils should not have been suspended just because of their difference in political views, and their courage to express them. How to cite Tinker vs. Des Moines., Essay examples

Summary To Preface To The Lyrical Ballads Essay Example

Summary To Preface To The Lyrical Ballads Essay Example Summary To Preface To The Lyrical Ballads Paper Summary To Preface To The Lyrical Ballads Paper In his Preface to the 1798 edition of the Lyrical Ballads, Wordsworth presented his poetic manifesto, indicating the extent to which he saw his poetry, and that of Coleridge, as breaking away from the artificiality, triviality or over-elaborate and contrived quality of eighteenth-century poetry. The Preface is itself a masterpiece of English prose, exemplary in its lucid yet passionate defense of a literary style that could be popular without compromising artistic and poetic standards. Yet it is also vital for helping us to understand what Wordsworth and Coleridge were attempting in their collection of verse, and also provides us with a means of assessing how successfully the poems themselves live up to the standards outlined in the Preface. The Preface covers a number of issues and is wide-ranging in its survey of the place of the Lyrical Ballads on the contemporary literary scene. The topics covered include the following: 1. The Principal object of the poems. Wordsworth, in this extract, places the emphasis on the attempt to deal with natural (rather than cosmopolitan) man, arguing that such men live much closer to nature and, therefore, are closer to the well-springs of human nature. Behind this, we can see how much Wordsworth owes to that eighteenth-century preoccupation with natural Man, associated particularly with the writings of Rousseau. He sees his poetry, in its concerns with the lives of men such as Michael, as an antidote to the artificial portraits of Man presented in eighteenth-century poetry. The argument is developed when he outlines his reasons for dealing with humble and rustic life. 2. For Wordsworth (and Coleridge) this choice of subject matter necessarily involves a rethinking of the Language of poetry. Note, however, that Wordsworth admits to some license in tidying up the language of ordinary men. Does this affect the persuasiveness of his theories about natural men? 3. This leads Wordsworth to an attempt to define poetry and its effects on the reader. Wordsworths project is an idealistic one, and clearly Poetry, for him, has a vital role in educating the mind and sensibility of his readers, a moral purpose. This quotation illustrates how important this benevolent effect is for the reader. 4. Inevitably, perhaps, the above leads Wordsworth towards asking What is a Poet? His answer illustrates the underlying assumptions about the poet as the genius, as the special person, capable of re-articulating thought and feeling so as to educate the reader. Glossary Object The principle object, then proposed in these poems was to choose incidents and situations from common life, and to relate and describe them, throughout, as far as possible in a selection of language really used by men, and , at the same time, to throw over them a certain colouring of imagination, whereby ordinary things should be presented to the mind in an usual aspect; and, further,, and above all, to make these situations and incidents interesting by tracing in them, truly though not ostentatiously, the primary laws of our nature: chiefly as regards the manner in which we associate ideas in a state of excitement. Humble and rustic life Humble and rustic life was generally chosen, because in that condition, the essential passions of the heart find a better soil in which they can attain their maturity, are less under restraint, and speak a plainer and more emphatic language; because in that condition of life, our elementary feelings co-exist in a state of greater simplicity, and consequently, may be more accurately contemplated, and more forcibly communicated; because the manners of rural life germinate from these elementary feelings, and, from the necessary character of rural occupations, are more easily comprehended, and are more durable; and lastly, because in that condition the passions of men are incorporated with the beautiful and permanent forms of nature. Language The language, too, of these men has been adopted (purified indeed from what appear to be its real defects, from all lasting and rational causes of dislike and disgust) because such men hourly communicate with the best objects from which with the best part of language is originally derived; and because, from their rank in society and the sameness and narrow circle of their intercourse, being less under the influence of social variety, they convey their feelings and notions in simple and unelaborated expressions. Accordingly, such a language, arising out of the repeated experience and regular feelings is a more permanent, and a far more philosophical language, than that which is frequently substituted for it by Poets, who think that they are conferring honor upon themselves and their art, in proportion as they separate themselves from the sympathies of men, and indulge in arbitrary and capricious habits of expression, in order to furnish food for fickle appetites, of their own creation . Definition of poetry For all good poetry is the spontaneous overflow of powerful feeling: and though this be true, Poems to which any value can be attached were never produced on any variety of subjects but by a man who, being possessed of more than usual organic sensibility, had also thought long and deeply. For our continued influxes of feeling are modified and directed by our thoughts, which are indeed the representative of all our past feelings; and, as by contemplating the relation of these general representatives to each other, we discover what is really important to men, so by the repetition and continuance of this act, our feelings will be connected with important subjects, till at length, if we be originally possessed of such sensibility, such habits of mind will be produced, that by obeying blindly and mechanically the impulses of these habits, we shall describe objects, and utter sentiments of such a nature, and in such connection with each other, that the understanding of the Reader must nece ssarily be in some degree enlightened, and his affections strengthened and purified. What is a Poet? He is a man speaking to men: a man, it is true, endowed with more lively sensibility, more enthusiasm and tenderness, who has a greater knowledge of human nature, and a more comprehensive soul, than one supposed to be common among mankind; a man pleased with his own passions and volitions, and who rejoices more than other men in the spirit of life that is in him; delighting to contemplate similar volitions and passions as manifested in the goings-on of the Universe, and habitually compelled to create them where he does not find them. To these qualities he has added a disposition to be affected more than other men by absent things as if they were present; an ability of conjuring up in himself passions, which are indeed far from being those produced by real events yet (especially in those parts of the general sympathy which are pleasing and delightful) do more nearly remember the passions produced by real events, than anything which, from the motions of their own minds merely, other men are accustomed to feel in themselves:- whence, and from practice, he has acquired a greater readiness and power in expressing what he thinks and feels, and especially those thoughts and feelings which, by his own choice, or from the structure of his own mind, arise in him without immediate external excitement.

Service marketing 7 P for JetBlue Essay Example | Topics and Well Written Essays - 1000 words

Service marketing 7 P for JetBlue - Essay Example However, the problems associated with service delivery and brand sentiment requires that JetBlue offer more discounted package and travel options as a means of reinforcing their price differentiation and satisfying their value proposition. Product is reflected by its provision of travel vacation packages on reputable sites such as Priceline and Travelocity, as well as JetBlue Getaways, a self-managed website offering custom-designed packages (JetBlue, 2010). As with the pricing consideration, JetBlue should expand these product offerings to illustrate the depth of its value proposition and value consciousness. Place is satisfied by having many fleets and routes established throughout the nation, thus adding convenience to the consumer experience. However, the majority of revenues come from New York and Florida, as Jet Blue has the most presence in these locations. The business should expand its market presence and capacity to improve place availability that can be used in promotions. Promotion is lacking at JetBlue. The company relies heavily on social media to create relationships with customers and promote its value (JetBlue, 2011). Social media is not effective in all markets, thus the business should invest additional capital in promotion to fully advertise its value proposition and gain more market attention. The expanded dimension of physical layout is somewhat restricted by its low cost model, as improving physical layout requires less overhead or more budgeting in this area. However, by offering customers more airport-based facilities and improvements on-board will improve its competitive position. In terms of people, the business requires more cultural development to ensure a culture of service excellence, something significantly damaged in reference to the Jet Blue brand. Finally, the business needs to change its
