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 geometrical ly) 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.

A Revelation to me Essay

When I was a kid, I got almost anything I wanted. I had travelled to China and seen the Great Wall. I travelled to Brisbane to see the Coral Reef and I even travelled to Italy and saw places like the Coliseum and the Sistine Chapel. However, to me, Singapore was the be all and end all of the world. I had lived there for 11 years and all my wants and needs were met on that small island. I could walk anywhere without worrying about getting kidnapped. I could take a taxi and not worry about the driver cheating you. I could even leave the house 10 minutes for a lesson and not worry about being late. I had a lovely school, a nice group of international friends and moreover a house in a pristine location. All was good. One day, my dad was at work and my brother was at a sleepover. My mother took me to my favorite restaurant at that time†¦McDonalds. I knew something was fishy, because I hadn’t done anything good, but I went along with it. Then she brought me a FULL Meal. Hmmmm†¦suspicious but I again parried it off. Then she upsized it. Ok! Something was wrong. So when I went to the table to eat my Upsized, full meal of McDonalds, I asked my mum â€Å"What’s going on? What’s the special occasion?’ And she replied, â€Å"Nothing Rushad. Can’t we just have a mother, son outing?† I looked at her in the eye and I could tell something was wrong. â€Å"Ok, fine.† She said. Paused. Took a bite from her burger. Swallowed. Then said â€Å"We are moving from Singapore.† â€Å"Don’t lie.† I laughed. â€Å"You can’t be serious! MUM!† But she just shook her head, like a bothered elephant and said â€Å"I’m sorry.† â€Å"But I don’t want to move.† And she told me the words I will never forget: â€Å"Life is like McDonalds. One day you get the Big Mac, whilst others you just get simple Chicken Nuggets. However, sometimes, you only get what’s available and have no say in the matter. Do you think a chicken wants to be killed to fill your stomach? Or a cow slaughtered to fill you up? No, sometimes, you have to accept defeat and walk along the path your life has chosen.† This was a turning point in my life. I realized that in life, you don’t always get what you wanted. Fortunately, some people learn this in simple ways such as not winning the game you wanted, or not getting that pretty girl to go out with you. Unfortunately for me, I learnt this the hard way. Leaving all that I knew behind, to start a fresh life in Jakarta. Sometimes you only want something, like staying in Singapore, because it’s the safe way out. However, moving to Jakarta was a risk and a scary adventure.

Art and Human Nature Essay

When discussing art it has continuously been examined how much it is applied to human nature. In The Art Instinct by Denis Dutton he spend an entire chapter discussing the colorations between the two. Art can be seen in human nature through its history, it’s comparison to language, and its creation from humans through genetics and their tendencies. Language has always been considered a part of human nature. All culture through all ages has some manner of language. Though it changes throughout the world with over six thousand known types, the universal ability to communicate is unquestionable â€Å"Despite vocabulary and surface grammar differences †¦ languages are never mutually incommensurable †¦ This is possible because language structure is shared across cultures and because languages are ties to universal prelinguistic interests, desires, needs, and capacities (30). Language is cross-cultural and though the mannerism and speech are different they are all inherent in their ability. At the same time one cannot argue that each language and gesture changed throughout the different culture. This is how language can be considered so universal in human nature. Art can be said to have the same universality of language. Like language it has transcended through all cultures and history. Different cultures all express them in a different way, and though everyone doesn’t necessarily understand all others cultures art, it is still a human universals. Also like language, art has the innate ability throughout all societies. Art in many way is very comparable to the human nature of language â€Å"The field of natural languages resembles the field of art considered cross-culturally: both exhibit an interplay between, on the one hand, deep, innate structures and mechanisms of intellectual and emotional like and, on the other hand, a vast ocean of historically contingent cultural materials† (31). With these many colorations art appears essentially connected to human nature. This thought that art has coloration with human nature has been around throughout history. Plato though rejected art as a form of knowledge, he still admitted it connection with nature. He saw art as an imitation of nature, which was already the imitation of the Forms, which make up our true reality. This he felt was disillusion, which brought out the worst customs of human nature. Either it represented a misleading view of our world in the sense of the beauty always found in art, but not in true reality. Or that it feeds our most basic instincts From a Platonic point of view, much of the violent entertainment offered by dramatic form – from the theater of the Greeks to the violence and animal passions of today’s entertainment media †¦ For Plato, the arts at their worst are bad for the soul because they engage and reward its basest elements (32). Though you sense that Plato fears the dangerous of the arts, this is only because he admits the inherit nature of it. Aristotle however has quiet a different opinion of art. He realized that with the variety in art it provides awareness into the human condition. In his works on drama and poetry he demonstrates that impact that art has had throughout the culture and history of his own society. Also he argues for the natural tendency that mankind has to represent themselves with art expresses the innate nature of it â€Å"Human beings are born image-makers and image-enjoyers† (33). Though the idea behind art and its connect between human nature is not always the same, it has existed during the course of history. Like art, human nature itself has been questioned on wither it is truly natural or has evolved over time and cultures. With the evolution of man many of human instincts has developed over time. Natural selection over thousands of generations have helped hones many skills needed to survive throughout mankind’s existences. These effects over many generations can be considered part of what makes up human nature â€Å"pressure over thousands of generations can deeply engrave a physical and psychological traits into the minds of any species (42). However it can also be argued that much of natural instincts come from our social nature. There is always the inherent hunter-gather sense that all humans have, but on the other side are the social tendencies we all have in common Human beings, for example, are curious about their neighbors, like to gossip about them, pity their misfortunes and envy their successes. People everywhere tell lies, justify and rationalize their own behavior, exaggerate their altruism. Human beings like to expose and mock the false pretentions of others. They enjoy playing games, telling jokes, and using poetic language (45-46). This social nature can be seen as innate within all cultures. Both this and genetic predispositions of humans is what human nature is derived from. This is where Dutton true argument comes full circle. Human nature no matter its origins is what makes up humans and all that they create. With our natural instincts we developed many tendencies, and theories. Our history as humanity we have gone through many things such as survival, not only those from the environment, but from the social forces that surrounds us. All of this is what truly makes up human nature, and from all this is where we create art. This is what makes humans what they are, and with that what they feel inspired to create no matter the culture and its form of art. This is how he reasons that art is human nature â€Å" eventually produced the intensely social, robust, love-making, murderous †¦ knowledge- seeking, arguing, clubby, language-using, conspicuously wasteful, versatile species of primate we became. And along the way in developing all this, the arts were born (46). Since art is derived from all that is human nature how can itself not be human nature. Through its colorations with language, the history, and the effects that human genetics and social tendencies have had art can be considered to be a part of human nature. Art like human nature has transcended throughout all of mankind’s existence. Wither art will ever be considered a part of human nature, its impact on humans not only through history but culture cannot be denied. Dutton, Denis.

AIDS Essay Example | Topics and Well Written Essays - 1000 words - 5

AIDS - Essay Example According to UNAIDS estimation at present, there is an approximation of 33.4 million people across the globe living on this face of earth while suffering from AIDS and every year estimated two million people expire from AIDS and its related illnesses. UNAIDS has approximated (UNAIDS, 2008). The case is even more critical in Sub-Sahara region of Africa where every 7 out of 10 deaths take place due to AIDS. Moreover, the region has almost sixty-six percent living case of AIDS and the percentage of new AIDS infection in children is as much as ninety percent (Stine, 2009). The cause of AIDS is the HIV virus. It is the virus that slowly weakens the human immune system. HIV increasingly does damage to the immune system cells therefore, the human body gets more prone to these infections, to which it has trouble in fighting back. A person diagnosed with AIDS is usually at the very high and advanced level of HIV infection flourishing in its body. The development of HIV in a human body is a slow process and it can take even years for a person with HIV virus to become an AIDS patient (AIDS.org, 2009). The symptoms of AIDS are though, not as vivid and obvious as the symptoms of other diseases. The person diagnosed with aid has the obvious illnesses related to AIDS. These AIDS related symptoms or conditions include infections, cancer, or tumor. These infections are opportunistic infections because of the reason that they develop in any human body due to the weak immune system. A person can suffer from AIDS with or without these opportunistic infection, the other symptoms are the tumor or cancer in any part of the human body due to AIDS. Moreover, the diagnosis of AIDS is also positive when the total number of human immune system cells decrease to a certain point. The major channels through which the transmission of AIDS takes place are the sexual intercourse, getting exposed to the infected parts of body or fluids, and from mother to

Man Killed in Sydney Shooting Essay Example | Topics and Well Written Essays - 2000 words

Man Killed in Sydney Shooting - Essay Example Local people are strictly prohibited to get into the area until the investigation process is in progress and police advice the people for not to come across the street and try to avoid it. However, even after several primary investigation process police is still unable to identify any criminals or suspects. As the shootout was held in the evening the police have decided to close the road from late evening. Even though the investigation is taking place still the criminals are still free and no one is yet arrested by the police. The case is in progress and the murderer is still undetected. Moreover, the increasing number of crime in Australia is affecting its social and political stability to a large extent. Thus, the local people are getting affected by the increasing criminal activities in Australia (The Australian, 2014). The Social Structure Theory mainly implies the relationship between various attributes of the society. The social structure theory is mainly based on the three modules those are a strain, cultural deviance theory, and social disorganization theory. The objective of these components of the theory is to provide support for understanding individual behavior towards the criminal behavior. In this context, the cultural deviance fits appropriately for the case. The cultural deviance theory is a combination of the social disorganization and strain theory. The criminal activities taking place within the society, which is mainly witnessed amid the lower grade people with a poor mentality. From the above case, it is found that the crime has taken place in a roadside area. Police, however, suspects that there might be some involvement of the mafia gang who are experts in this kind of activity as referred to in the case. The cultural deviance theory signifies that the upbringing or the family cu lture of a person can lead them towards the crime.  

Compare and contrast two artworks of the 19th century Essay

Compare and contrast two artworks of the 19th century - Essay Example On the other hand, Paul Cezanne used Madame Cezanne’s portrait to express classical calm and ultimate simplicity. In the portrait, Cezanne does not capture the social status of his wife and therefore there is nothing to express her status as a model, lines and other artistic features are used to express emotional distance (Athanassouglou-Kallmyer, and Provence 234). This essay will give a brief biography of both artists and expound on similarities and differences of Comtesse de La Tour-Maubourg and Madame Cezannes portraits as mediums of expression. Theodore Chasseriau was born in Samana Dominican republic and his family moved to Paris when he was the age of three. His artworks have been influenced by Ingres and therefore his paintings, drawings and styles exhibited in his finished works are relatively close to the works of Ingres. Chasseriau started working at the Master’s Studio at the age of eleven where he met Ingres and continued working until Ingres left to lead t he Academic de France in Rome in 1834. Through his brother’s connections, he was able to draw portraits of elites in both the church and the state and his works were easily accepted in the society. He started producing his artworks in 1836 and moved to Rome in 1841 to join his mentor Ingres. Chasseriau’s greatest artworks were the Othello etchings in 1844 and a trip to Algeria exposed him to Orientals subjects that he was learning and was interested in exploring in the field of art. After his death, the staircase for Cour-des-Comptes that symbolized war and peace were destroyed by fire in 1846. Paul Cezanne was born in 1839 in Aix-en-Provence in France in a well-off family that assured his financial stability and supported him in his artistic works, an advantage that was missed by most artists of the time. Cezannes father wanted him to study law and he was forced to study Law at the University of Aix. However, he inherited a vivacious and romantic touch from his mother , and in 1857 he went for drawing classes under Joseph Gilbert at the Free Municipal School of Drawing at Aix. Because of a strong desire to pursue his passion, Cezanne went against his father’s wishes and under the encouragement of Zola, delved into artistic works, and moved to Paris where he developed his artistic skills, through the mentorship of Camille Pissarro. In his early works, Cezannes paintings were majorly large heavy figures in the landscape that were painted through imagination. However, as he developed, he advanced to working and painting from direct observation and this culminated into a light airy painting style. He struggled to create a connection between his observations and classical compositions. The Comtesse de La Tour-Maubourg portrait is symmetrical, with its proper positioning and proportional utilization of space allowing the artist to fix the background and other natural features in a proper proportion and distance in reference to the subject. On th e other hand, the portrait of Madame Cezanne in a red dress her posture sitting on the yellow chair and the details of wall bring out a very symmetrical relation of the different features that have been captured. The Primary colors, which are blue, red and yellow, are used to bring

Lincoln Presidency against that of Johnson Essay

Lincoln Presidency against that of Johnson - Essay Example Precisely the paper will argue out if the Lincoln administration was worthy of more praise than Johnson’s presidency. The first crucial policy enforcement that Lincoln is highly accredited for over his predecessors and successors was the Emancipation of Slaves who hugely consisted of African Americans. President Buchman, Lincoln, and Johnson all believed that the Constitution protected the institution of slavery (Jones, 1999). However, Lincoln alone understood that the constitution and the union that it had created would be preserved only by redefining the principles on which the country was cemented upon, such as all men are created equal. This led to the passing of the second confiscation act in 1862 in a move to weaken the rebellion that opposed Lincoln by freeing the slaves since most of the rebel leaders were slave owners. Furthermore, the emancipation declaration that Lincoln brought into effect was to free slaves even in states that were not under the union control. As one of Lincoln’s officials pointed out Lincoln was the first great man, who talked in the United States in a manner th at suggestively deemed that there was no difference between any two people, especially on the differences of color (Jones, 1999). In respect to domestic policies, Lincoln led to a myriad of substantial changes in the government policies that faced an impetus force of resistance. Lincoln created the first income tax in an attempt to finance the war and implemented military drafts that led to huge uproar and riots in the New York City. These and many other policies that Lincoln incorporated during his rule were meant to restore the union, which happened to be an overwhelming priority during his term. On the other hand, Johnson’s first priority was the restoration of the state and some of his notable contributions include, the halting of the construction of Bozeman trail.
