Nano Technology in Oil Industry Essay Introduction Nanotech applications Nanoparticles have been successfully used in drilling mud for the Last 40-50 years. Recently the other disciplines of the oil industry, such as exploration, primary and assisted production, monitoring, refining and distribution, are approaching nanotechnologies due to its immense Potential for Confronting challenges, performance improvement cost. Especially in ultra-deep water and artic environments, Severe reservoir conditions (high-temperature and high-pressure formations), nonconventional resources of energy,Heavy oils, tight gas, tar sandsreservoirs) Present nanotech applications in oil industry: Most of the major oil and service companies, such as BP, ConocoPhillips, Shell, Total and Schlumberger. done research in exploiting nanotechnologies to improve oil and gas production. Developing subsurface micro- and nanosensors that could be injected in oil and gas wellbores identification of nanotech potentialities applied to EOR issues. Recent published results speak about Single-Walled-Carbon-Nano Tube (SWNT) / Silica nanohybrids, active at the fluid interface, if delivered at the O/W interface, would react and modify the oil properties to increase oil mobilization, hence oil recovery. Researchers ars analysing the potential benefits derived by the application of nanomaterials, nanofluids and nanomembranes in oil industry. Sensors: Nanomaterials are unparallelled tools for the development of sensors and imaging-contrast agents due to the significant alterations in their optical, magnetic and electrical properties, along with their ability to form (electrically and/or geometrically) percolated structures at low volume fractions. Such nanomaterials, when combined with smart fluids, can be used as extremely sensitive down hole sensors for temperature, pressure and stress even under extreme conditions. The ultimate evolution of instruments for oil prospects is perceived to be nanorobots, which should really provide an effective mapping of the reservoir. Nanorobots still remain a dream,shared by the medical and oil sectors. But advances in nanosensors miniaturization are becoming a reality. Coatings: A corrosion-resistant material solution represented by nanometric thin films  and composites with nanostructured fillers are in the advanced stage. corrosion-resistant materials are the â€Å"just ready to happen † nanotechnology-based applications,due to its relatively low risk, high effectiveness and low complexity. Nanocoated, wear-resistant probes, made of tungsten carbide or boron nitride, enhance the life span and efficiency of the drilling systems. The same applies to the nano-layered corrosion inhibitors in pipes or tanks, which creates a permanent molecular coating on the surface of metals, eliminating corrosion. Nanofluids and nanomaterials for drilling and completion : Nanotechnology has opened the development of smart fluids† for drilling, production and stimulation applications. Nanofluids and nano-based additives exhibit major advancement by enhanced drilling by adding benefits like wettability alteration, improved drag reduction and sand consolidation. A specialized petroleum laboratory has developed an advanced fluid mixed with nanosized particles and superfine powder that significantly improves the drilling speed and can eliminate formation damage in near wellbore zone. With the synthesis of a new breed of elastomeric composites filled with carbon nanotubes or other strongly anisotropic nano-objects, a stronger, tougher and more rugged drilling tools and apparatus will be manufactured in future. These tools will ensure a significant weight reduction and facilitate self-sensing elements to be interrogated for the real-time monitoring of the most critical parts. Another important technique in the development of super-hard materials is the use of nanostructured dispersed-hardened materials .First generation of nanotech applications for improving hydraulic fracturing are represented by BakerHughes’s nanostructured metal composites, combined by magnesium, aluminium and other alloys, which offer both strength at lower weight and the ability to â€Å"dissolve† away under certain conditions. Another example is the proppant produced by Oxane Materials, constituted by nano-structured ceramic material which is as strong as but lighter as ceramic proppant. A possible solution for mitigating fines, by nanocrystals for treating hydraulic fracture proppant packs to fix formation fines. Nanotechnology application for reservoir monitoring for enhanced oil recovery Nanomembranes: A new generation of lightweight and strong nanomembranes is being developed and employed, Which will remarkably enhance  the exploitation of tight gas by providing efficient methods for removing impurities, separating gas streams and enabling GTL production. Nanoporous and nanoparticulate materials are also quite encouraging to manage the Health, Safety, Environmental, risks arise due to presence of CO2 and H2S in hydrocarbon mixtures. Nanotechnology application for reservoir monitoring The petroleum sector and the medical visualize the dream of a nanosensor able to provide in-situ information about the systems under analysis. The most complicated and Complex challenge faced by oil industry is that it requires strong technical improvements in injected nano sensors into the reservoir, to face placement and recovery, protection in harsh environments , 3-D location, sensors powering and data storage retrieving. For example, the quantity of oil present in a reservoir could be assessed based on the amount of material lost or retained during the travel time, or the extreme conditions (temperature, pressure, salinity gradient) at which the nanoparticles were exposed and for how long, could be determined. The idea can be to pump nano-sensors in the reservoir periodically so as to regularly monitor changes in the well/field conditions.In turn, this could result in enhanced production efficiency. Several possible applications and exploitation schemes are currently under study with nano-devices injected into a reservoir. A novel paramagnetic nanoparticles into proppant structures together with these smart proppant could help in mapping the fracture efficiency using detectable contrast agents. Further nanoparticles could preferably segregate into different fluid portions, hence providing enhanced characterization of the reservoir and, fianlly , improved oil recovery,due to their miniscule dimensions, increased surface area and high mobility. Nanotechnology application for enhanced oil recovery: The greatest challenge at present is the possibility of increasing the efficiency of hydrocarbon production, both by improving the current EOR methodologies and by developing alternative technologies. The current researches indicate the new generation nano-agents should modify the properties of the injected fluid, in terms of viscosity, density, thermal conductivity and specific heat and modify the fluid-rock interaction properties, .The use of two different types of polysilicon nanoparticles (one nanometer-scale) in oil fields  improves wettability, to enhance water injection and improve oil recovery. The application of paramagnetic nanoparticles for EOR , possess a unique combination of fluidity and capability to interact with a magnetic field. The addition of a surfactant would greatly reduce the interfacial tension in waterwet reservoirs due to the presence of a dipole moment.The reservoir fluid molecules align, thus reducing the resistance to flow. ConocoPhillips, aims at creating a new class of polymer-type nanoparticles that can be incorporated with EOR injection fluids to improve hydrocarbon recovery by penetrating small pore throats without being trapped and hence the a mount of expensive injection can be decreased. The University of Alaska Fairbanks investigated The possibility of improving gas injection for the Alaska North Slope heavy oil recovery. Metal nanoparticles. reduce the viscosity of the heavy oil. Using super critical CO2 and Viscosity ReducingInjectant (VRI) saturated by nanoparticles, exploit the thermal properties of nanoparticles for improved heat transfer to heavy oil; explore the effects of Poly Di Methyl Siloxane and metal nanoparticles on density and viscosity for reducing mobility and viscous fingering Phenomena . When dealing with extremely low permeability reservoirs, conventional approaches to water flooding cannot provide recovery factors greater than 0.2. This is mainly due to capillary forces which are very strong in narrow pore channels. With low-permeability reservoir rocks, the level of purity and filtration of injected water is one of the most important issues for a significant oil recovery. With rocks characterized by a permeability of 0.1 ÃŽ ¼m2 the recovery factor deviates from an average of 0.4 by less than 10% if particulates in injected water are smaller than 200 nm. Nevertheless, with a rock permeability of 0.05 ÃŽ ¼m2 the recovery factor is dramatically approaching zero with the same particle ssize. A traditional water flooding technique is obviously unproductive in this latter case, unless water is filtered and purified of particulates down to at least 100 nm. Innovative water nano-filters are to be specially designed both to ensure uniform pore throats and the ability to recovery tens of billions of tons of oil. Some feel that oil is essentially a nanoliquid, with asphaltenes being the dominant part, flowing in a micro and often nanoscopic environment (i.e., the porous media). According to that,it seems justifiable to consider most of the oil and gas production technologies, reservoir treatments and  stimulation as nanotechnologies. Under this point of view, current petroleum science is relying on the study and control of physical chemical phenomena occurring at the nanometer scale and the ability to correctly model the reservoir flow plays an important role. However, a suitable tool to reliably describe coupled phenomena is still missing. The present approach being discussed is, for creating nanorobots to monitor individual pores and channels and hydrocarbon flow, exchange information and identify zones which intensify the extraction or the injection of water. CONCLUSION: Nanotechnology Application to the oil industry has an immense potential benefits. Some applications are already available,while others could come from Complementing the solutions developed for the biomedical, automotive, aerospace, chemical and, textile Industries. Well drilling, fracturing and cementing as well as new generation membranes for gas separation already rely on nanotech solutions. At present efforts are being made to design nano-sensors for reservoir characterization and monitoring and to produce nano-fluids for improving EOR processes. Promising results have been obtained from laboratory experiment, but field tests are still in progress..The future of nanotechnology applications is remarkable.

Themes in The Old Man and the Sea :: Old Man and the Sea Essays

Themes in The Old Man and the Sea    The Old Man and the Sea is a heroic tale of man’s strength pitted against forces he cannot control. It is a tale about an old Cuban fisherman and his three-day battle with a giant Marlin. Through the use of three prominent themes; friendship, bravery, and Christianity; the â€Å"Old Man and the Sea† strives to teach important life lessons to the reader. The relationship between the old man and the boy is introduced early in the story. They are unlikely companions; one is old and the other young, yet they share an insuperable amount of respect and loyalty for each other. Santiago does not treat Manolin as a young boy but rather as an equal. Age is not a factor in their relationship. Manolin does not even act as a young boy; he is mature and sensitive to Santiago’s feelings. He even offers to go against his parent’s wishes and accompany Santiago on his fishing trips. Santiago is viewed as an outcast in his village because he has not caught any fish for more than eighty-four days and is therefore â€Å"unlucky†. Nonetheless Manolin is loyal to Santiago and even when his parents forbid him he wants to help his friend. Their conversations are comfortable, like that of two friends who have known each other for their whole lives. When they speak it is usually about baseball or fishing, the two things they have most in common. Their favorite team is the Yankees and Santiago never loses faith in them even when the star player, Joe DiMaggio is injured with a heel spur. In this way Santiago not only teaches Manolin about fishing but also about important characteristics such as faith. In the story Santiago’s bravery is unsurpassed but it is not until he hooks the â€Å"great fish† that we truly see his valor and perseverance. Through Santiago’s actions Hemingway teaches the reader about bravery and perseverance in the face of adversity. He demonstrates that even when all is lost and seems hopeless a willful heart and faith will overcome anything. Santiago had lost his â€Å"luckiness† and therefore the respect of his village. Through the description of his cabin we also suspect that Santiago is a widower. Although Santiago has had many troubles he perseveres. He has faith in Manolin, in the Yankees, in Joe DiMaggio, and most importantly in himself.

Remembering My Childhood Essay

â€Å"I want to be just like you† Growing up, Sedaris had a good life. He had a loving family that supported him and made sure he was well taking care of. Sedaris’ friend, Hugh had a very difficult lifestyle. When Hugh was growing up as a child, he saw things that children should not be forced to witness. Hugh’s class took a field trip to a slaughterhouse one day, where they were treated to a pig’s execution. â€Å"†¦One of the brothers drew a pistol from his back pocket, held it against the animal’s temple, and shot the piglet, execution-style.† (Paragraph 6, page 109) At another occasion, Hugh witnesses a dead man on a telephone pole. â€Å"Unlike me, he left the theater two hours later, to find a dead man hanging from a telephone pole at the far end of the unpaved parking lot.† (Paragraph 10, page 110) Hugh was often neglected by this family and spent majority of his adolescence with surrogate parents. Hugh’s life wasn’t the not good at all but Sedaris w anted Hugh’s life. Sedaris describes why he believed his childhood was so bland in comparison to his friend Hugh’s childhood. Sedaris compared his childhood to Hugh’s childhood so much until he started to envy Hugh. Sedaris stated, â€Å"We had a collie and a house cat†¦ They had a monkey and two horses named Charlie Brown and Satan†¦ I threw stones at stop sighs†¦ Hugh threw stones at crocodiles.† (Paragraph 8, page 109) Sedaris thought throwing stones at crocodiles was really fun. He did not realize what kind of danger Hugh was really in. â€Å"No fifteen-foot python ever wandered onto my school’s basketball court†¦ I begged, I prayed nightly, but it just never happened†¦ A military coup in which forces sympathetic to colonel arrived late at night to assassinate my next-door neighbor.† (Paragraph 13, page 111) Sedaris wanted to everything Hugh had. He wanted to travel the around the Continent of Africa too. Sedaris loved Hugh’s childh ood but Hugh did not find his life to be so great. Hugh’s family had moved to Mogadishu, Somalia. Since there was not any English-speaking schools there, Hugh had to stay with a family he did not know. â€Å"Hugh was sent back to Ethiopia to live with a beer enthusiast his father had met at a cocktail party.† (Paragraph 16, page 112) While Hugh  lived with the Hoyts family, he did not feel welcomed at all. â€Å"They invited him to join them at the table, but that was as far as they extended themselves.† (Paragraph 16, page 112) Hugh was not able to celebrate his birthday nor was he able to talk to his family. â€Å"No one ever asked him when his birthday was, so when the day came, he kept it to himself†¦ There was no telephone service between Ethiopia and Somalia.† (Paragraph 16, page 112) The Hoyts had children and they missed treated Hugh every chance they could get. They would say things to Hugh for instead, â€Å"Hey that’s our sofa you’re sitting on† and â€Å"Hands off t hat ornamental stein†¦ It doesn’t belong to you.† (Paragraph 16, page 112) Hugh had a hard life growing up. His life was not what Sedaris make it to be. Although Sedaris had a better life than Hugh, he still envied Hugh’s childhood. He started to take Hugh’s childhood stories and make them his own. â€Å"Rather than surrender to my bitterness, I have learned to take satisfaction in the life that Hugh has led†¦ His stories have, over time, become my own†¦ When my own experiences fall short of the mark, I just go out and spend some of his†¦ It is with pleasure that I sometimes recall the dead man’s purpled face or the report of the handgun ringing in my ears as I studied the blood pooling beneath the dead white piglet.† (Paragraph 21, page 113) There once was a time in all of our lives where we wanted something someone else had and their lifestyle. Do we really see their struggles or are we just looking at what our eyes could see? We should not envy other people and the things they have. Some people work really hard to get the things they have today. We never know what another person had to do or go through in order to get what they have. We should be grateful to God for the things we do have.

The Foreign Exchange Regulation Act - 1954 Words

The Foreign Exchange Regulation Act or FERA, passed by the Parliament in 1973, was framed to eradicate crimes relating to foreign exchange in the country , such that the economic development, which was still in its pre-liberalization era and thus slow, was not adversely affected. It was also to preserve the scarce Forex or foreign exchange currency in the country and hence tried to keep a strict control on these particular resources. However, it was repealed and replaced by the Foreign Exchange Management Act (1999) to reinforce and fortify the development and the maintenance of the foreign exchange resources in the country. It was more extensive, comprehensive and since the floodgates of the economy had opened after liberalization in 1991, had more scope to actually reinvigorate the availability of foreign exchange in the country. This act, in essence, was formed to keep in check the foreign exchange resources in the country and hence all business deals involving foreign exchange need to be authorized by the Government. It is drastic in nature as it does not allow arbitrary trade in foreign exchange of any form, as this is a resource that needs to be willfully protected. Under this Act, Lalit Modi had performed a number of violations.
