Role of Organic Geochemistry in Petroleum

Role of Organic Geochemistry in Petroleum A review on role of organic geochemistry in petroleum;  characterization and applications of different basins Harish Chandra Joshi Abstract Petroleum is a mixture dominantly of hydrocarbons with varying proportions of non-hydrocarbon constituents and traces of organometallic compounds. Generally Petroleum has an average composition of 85% carbon, 13% hydrogen, and 2% of sulphur, nitrogen and oxygen. The aim of study is to find out the physicochemical and genetic property of petroleum. In this study biomarkers, age specific biomarker and reservoir geochemistry can be used for the characterization, correlation and/ or reconstruction of the depositional environment as micro and macro fossils used by the geochemist. Keywords: Biomarker, Genetic Characterisation, Kerogen, Geochemical Fossils. Introduction The name geochemistry was first used by the Swiss chemist, Christian Friedrich Schonbein in 1838. Petroleum geochemistry is the application of chemical principles to the study of the origin, migration, accumulation, and alteration of Petroleum (oil and gas) and the use of this knowledge in exploring and recovering Petroleum. Organic chemistry is the branch of chemistry that deals with the distribution and composition of carbon compounds. Geochemistry is the study of the chemical composition of the earth, minerals, ores, rocks and also is the study of the origin of petroleum. The major tasks of geochemistry can be summarized as follows: The study of the relative and absolute abundances of the elements and of the atomic species (isotopes) in the earth. The study of the distribution and migration of individual elements in the various parts of the earth (the hydrosphere, atmosphere and lithosphere etc.), and in mineral and rocks, with the object of discovering their distribution and migration. Exploration companies have used petroleum geochemistry in hydrocarbon exploration. The most and major objective of exploration geochemistry, is to reduce the risk of drilling dry holes. Petroleum geochemistry is based on the organic origin of the oil and gas whereby organic matter obtained from dead plants and animals. Organic matter is converted to hydrocarbons in the subsurface through various major three stages of transformations diagenesis, catagenesis and metagenesis. German scientist Treibs (1936) reveal a relationship between chlorophyll-a in living photosynthetic organisms and porphyrins in Crudes of petroleum. This link provides a strong evidence of organic origin of Petroleum. From the starting of the Precambrian till the Devonian, the unique primary producer of the organic matter were marine phytoplanktons. Since the Devonian an increasing amount of primary production has been contributed by higher terrestrial plants. At present cenario marine phytoplankton and higher terrestrial are estimated to produce about equal amounts of organic carbon. On increases the burial depth, porosity and permeability decrease, and temperature increases. Thus lead to the change a gradual halting of microbial activity and thus eventually called ‘organic diagenesis to a halt. As the temperature rises, thermal reactions become increasingly. This second transformation phase, called catagenesis, during the catagenesis kerogen begins to decompose into smaller, more mobile molecules. In the early stage of catagenesis, kerogens are still relatively large; these are precursors for petroleum and are called â€Å"bitumen†. In the late stages and final transfo rmation stage, called ‘metagenesis’. During metagenesis the principal products consist of smaller gas molecules. Further, kerogens formed from different organic matter, or under different diagenetic conditions, are chemically clear which has a significant effect on hydrocarbon generation. Characterization of crude oil by Analytical Methods Firstly sampling of crude oils is required for their characterization. Oil should be collected as a single- phase sample under pressure conditions as they are in reservoir. Therefore for the geochemical studies, crude oil samples are collected at the well head under atmospheric pressure. Under these conditions light hydrocarbons of crude oils are lost completely or partly. Light hydrocarbon fraction gives the ideas only about the abundance and constituents of the light end of the oil. It is normally observed that the most abundant characteristics hydrocarbons are commonly in the light fraction. For required minimizing the effects of sampling error the crude oil is distilled at 2100C. The heavier fraction is considered the foremost part of the crude oil. It is used to describe the chemical composition of a crude oil and also to compare it with other crude oils. Analytical Techniques in Petroleum Exploration Petroleum system (Demaison, 1994; Hunt, 1996) comprise all those geological elements and processes that are necessary for an oil and gas deposit to occur in nature. These main elements are a petroleum source rock, migration paths, reservoir rocks, seals, traps and the geological approach that design each of them. Such systems involve a genetic relationship between the source rock and the petroleum accumulations, but proof of that relation force a geochemical correlation. organic geochemistry techniques available include surface geochemical prospecting, source rock geochemistry, crude oil geochemistry, natural gas geochemistry, biomarker geochemistry, isotope geochemistry etc. Biomarkers in Petroleum Biological marker or shortened to Biomarkers (Seifert and Moldowan, 1981) are complex molecules derived from once living organisms they are found in sediments and oil and show little change in structure from their parent molecules (Peters Moldowan, 1993 and Hunt, 1996). These compounds are also called as geochemical fossils (Eglinton and Cavin, 1967) because of their origin from living organisms. Such compounds may be derived from terrestrial (mostly plants, marine pelagic (mostly plankton) and marine benthonic (algae, bacteria and other microbes). Biomarkers are generally, microfossils less than 30 nm in diameter and are highly variable in their stereochemistry i.e. the spatial arrangement of atoms and groups in their molecules. The common use of the biomarkers in petroleum exploration may be enumerated as follows: Biomarkers are present in both and oil a source rocks so they provide vital information for the oil-oil and oil-source correlation. Organic matter type (source of organic facies) Depositional environment Extent of thermal maturation Degree of biodegradation Information about the age of the source rock ÃŽ ± and ÃŽ ² Geometry of Biomarkers Steranes obtain from the diagenesis of natural products sterols. Diagenesis converts sterol via chemical dehydration and microbial reduction to a steranes cholestane. Cholestane molecule is drawn in three dimensions as follows. The hydrogen at the 3 position points up above the plane of the molecule and that at the 5 position points down below the plane (Peters and Moldowan 1993) Commonly Used Biomarkers in Petroleum Exploration Normal Alkanes: Normal alkanes are a homologues series of saturated hydrocarbons of general formula CnH2n+2. All linear n-alkanes from C1 to C40 and a few beyond C40 derived from different sources have been identified in crude oils. Iso- and Anteiso-alkanes: Isoalkanes are 2-methyl alkanes and quite a number of these have been observed in crude oils as have been the anteiso-alkanes, the 3-methlyalkanes. Iso and anteiso alkanes are associated with n-alkanes in plant waxes where they comprise a approximate number of carbon atoms (about 25-31) with an odd predominance Figure 1. Showing common biomarkers like paraffins, Iso and ante-isoalkane Acyclic Isoprenoid: These are special type of Iso-alkanes in which one methyl group is attached to every fourth carbon atom in straight. Isoprene (methyl butadiene) is the basic structural unit composed of carbon atoms that is found in all biomarkers. The most common isoprenoids are pristane (C19) and Phytane (C20). Figure 2. Common Isoprenoid biomarkers in petroleum Terpenoids: Terpenoids can be classified based on structural types into diterpenoids and triterpenoids Diterpenoids are categorized into bicyclic and tricyclic diterpenoids. Triterpenoids are grouped into tetra and pentacyclic. The most knowing are pentacyclic and among these are hopanes. Hopanes are pentacyclic triterpenoids comprised of four 6-membered and one 5-membered ring. There is a side chain which can contain upto 8 carbon atoms. Thus the series comprise of C27-C35 hopanes. They are believed to have originated from polyhydroxybacteriohopane. Figure 3. Structures of Common Triterpanes Figure 4. Structures of Common Tricyclic and Tetracyclic Terpanes Steranes: Steroids can be classified as aliphatic and aromatic steroids (mono, di- and tri-aromatic depending on the number of aromatic rings). Steranes are a series of aliphatic steroids. The sterols in all eukaryotic organisms are precursors to the steranes in sediments and petroleum. Like the hopanes, steranes are abundant in sediments, rocks and petroleum, because their precursors (Sterols) are so common in living organisms. Cholesterol has eight asymmetric centers and might be expected to show as many as 28 or 256 stereoisomers. Figure 5. Chemical Structure of various steroids Porphyrins: Porphyrins are characterized by a tetrapyrrolic nucleus proved to be inherited from chlorophyll, the green photosynthetic pigment of plants and animals ,hemin, the red pigment of animal blood. These tetrapyrrolic organometallic compounds reported of the vanadium and nickel in petroleum. The major types of fossil porphyrin are deoxophylloerytrapyrrole (DPEP) and etioporphyrin (ETIO) porphyrin structure. Age specific biomarkers If biomarkers characterise a molecular record of life, they can be used for age determination. Certain age specific biomarkers like Oleanane present in oils derived from late Cretaceous or Younger. C11-C19 Paraffins, Odd carbon number prevalence in oil from many Ordovician sources. 24-n-propylcholestane, High in oils from Ordovician sources.Thus the biomarkers transport to the sources has proved to be of great help in geochemical characterization of the oils/condensates. Reservoir Geochemistry The main aim of reservoir geochemistry is to understand the distribution and origin of the petroleum, water and minerals in the reservoir and account for their possible spatial and compositional variation (Cubitt and England 1995). A better understanding of the fluids in the reservoir conduct to a better understanding in an area and prioritization of exploration thrusts. The principle factors responsible for difference in petroleum composition are the effect of organic facies variations, progressive source rock maturation, migration fractionation, gravity segregation, oil/water contact and non-uniform biodegradation of oil across the field. However these effects have been normalized by using ratios of peaks corresponding to compounds of similar molecular weight in the C10+ region of the chromatogram. The study of reservoir continuity is also the focus of the geochemical characterization to trace the nature and depositional conditions of the source organics, identification of the oil families and thermal maturity of the oils/condensates. When a set of chromatographic peaks has been selected, a variety of techniques are available for grouping of this data. One way is to use a polar plot of selected ratios by a star diagram (polygon plot) by plotting each peak ratio on a different axis of polar plot. Each data point is plotted from the centre of the concentric circles outward. The points are then connected to create a star shaped pattern characteristic of each oil. Applications of geochemical characterisation Biomarker and non-biomarker geochemical parameters are best used together to supply the most authentic geological interpretations to help solve exploration, enlargement, production and environmental problems. Prior to biomarker work, oil and rock samples are properly screened using non biomarker analyses. The strength of biomarker parameters is that they provide more detailed information needed to answer questions about the source rock depositional environment, thermal maturity and the biodegradation of oils than non-biomarker analyses alone. Different depositional environments are characterized by different assemblages of organisms and biomarkers. Commonly accept classes of organisms include bacteria, algae, and higher plants. Biomarker parameters are also an effective means to determine the relative maturity of petroleum through the entire oil-generative window. Conclusion On the basis of above observation major conclusions which have been derived from the whole study are as follows: The presence of complete range of normal alkanes upto nC36 and in some cases upto nC40. The presence of biomarker in oil indicates that oil may be terrestrial or marine. The terrestrial nature of the source is also strongly indicated by the steranes. Reservoir geochemistry of oils has been used to demonstrate the lateral/vertical continuity/compartmentalization.

The Promising Future of Chinas Economy Essay -- Economy

The Promising Future of China's Economy If China's economy grows as fast for the next 20 years as it has for the past 14, it will be the biggest economy on earth: I feel that China's drastic improvements over the last 14 years are overwhelming, with their Real GNP growing at a rate of 9% a year, which means by, 1994, China's economy will match the performance of countries like Japan and Taiwan. China's standard of living has also increased, and the number of people who were considered absolutely poor decreased approximately 63%. I feel with the vast amount of people living in China, and the economic activity booming like it is, China's exports will continue to grow, as well as the standard of living. This will create more revenue, and more capital for them to produce even more goods and become even larger, prospering as one of the biggest economies on the earth. I also feel that China should try to overcome its corrupt system and steadily move into a free enterprise system. Competition has been the key to China's success: I believe that competition has been the key to China's success. When Mr. Deng opened the free market, it brought the first signs of the farmers becoming more rich since the 1950s. His political genius allowed the farmers to become rich. He also introduced the "open-door policy" which is proving to be very beneficial, as they follow in the footsteps of their strong rich neighbours. Mr. Perkins believed four conditions must be met for a market system to work well in reforming centrally planned economy. I believe if China continues to improve its productivity, and the number of monopolies decrease as studies show, China will move into a capitalist front only to... ...ver the last several years. The party has a large role to play in China's transition to a full market economy. China is on its way. the West should prepare China's interests lay in foreign investment, trade and economic reform. China's main driving force was competition, and they proved that privatisation and settling the matter of ownership are not so critical in the early stages of reform. In the years ahead, China must choose between keeping the communist party or kepping the stunning economic growth. If they continue to grow at the rate China grows, and keep improving their economy, and join the likes of Japan, they can combine forces in all aspects against the west, military wise and economically wise. if China's economy grows as fast for the next twenty years like it has for the past fourteen, it will be the biggest economy on earth.

Nucleic Acids :: essays research papers

DNA is the single most important molecule found within cells. It is a stable polynucleotide, which contains coded information for inherited characteristics. It is contained in chromosomes in the nucleus of an eukaryot cell. The essential features of the Watson-Crick model are summarised below. 1. The two helical polynucleotide chains are coiled around a common axis. The two chains have opposite polarity i.e. they are antiparrallel. 2. The regular repeating sugar phosphate backbone of each strand lies on the outside of the helix. The purine and pyrimidine bases project inwards at 900 to the axis of the helix. 3.  Ã‚  Ã‚  Ã‚  Ã‚  The two strands are held together by hydrogen bonding between pairs of bases such that guanine always pairs with cytosine and adenine always pairs with thymine; this is called complementary base pairing 3. The diameter of the helix is 2.0 nm and adjacent bases are separated by 0.34 nm and inclined at 360 relative to each other. This means that each complete turn of the double helix contains about 10 base pairs. 4. The amount of guanine is usually equal to that of cytosine. The monomers of RNA and DNA are called nucleotides. Each nucleotide has three parts: A Five Carbon or Pentose Sugar The sugar will be one of two very similar pentose rings. Ribonucleic acids contain the sugar ribose. Deoxyribonucleic acids contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions. The Nitrogen-Containing Bases There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings, while the pyrimidines have only one. In DNA the purines are adenine (A) and guanine (G) and the pyrimidines are cytosine (C) and thymine (T). In RNA the purine bases are the same as in DNA, but the pyrimidines are cytosine and uracil (U). These rings have the chemical property of being bases because of the nitrogen atoms they contain. Adenine always forms 2 hydrogen bonds with thymine. Cytosine always forms 3 hydrogen bonds with guanine.

Google Search: Needle in the Haystack Essay

Searching for information on Google is like trying to find a needle in a haystack. Is that true? Was the library of the 19th century more efficient? Explain. We have access to more references in less time by searching for information on Google versus using an index card system in the 19th century library. A historical example is the traditional card catalog in a library, which essentially did not contain any raw data itself, but instead had a series of cards organized alphabetically so that each card pointed the user to a book that might contain the information for which he or she was searching. Much more common today are the metadata in Web sites that encode data so that the user can identify and retrieve desired information. (Bowles 2010). In this statement, libraries depended on an alphabetical card system to direct researchers to resources and references to possibly attain the information they were looking for. Once they found the books or encyclopedias they were looking for, they would still have to manually skim through to see if the information was sufficient to their search. With Google were able to type in exactly what we’re looking for and have immediate results. Google is like a virtual everything encyclopedia that has answers for everything. The more specific you enter your search the more specific your result will be. The only downside is having to decipher which searches are reliable and accurate on Google because of all the websites that allow people to add input and personal opinions versus just factual information. How is searching in a specific database, such as Ashford’s library, different from searching in Bing, Google, or Yahoo?  There are two main types of online information databases that you will encounter. The first is a public domain database, which is entirely free and open to anyone with a computer and an Internet connection. The second is a proprietary database, which is accessible only to someone who pays for a subscription or belongs to an institution that purchases a membership (Bowles 2010). Bing, Google and Yahoo are examples or public domain databases and Ashford Library is a proprietary database. Information on the Internet was created for many purposes such as to inform or persuade to present a viewpoint, and to create or change an attitude or belief. Although when used properly, credible information can be obtained through search engines- not everything recovered is from a credible source. Ashford Library is from a scholastic source and the information found within is from credible sources. Social networks allow people to connect for a variety of reasons in a digital environment.  You might join LinkedIn to meet business contacts, MySpace to find a band member, or Facebook to see pictures of old friends and meet new ones. Whatever environment you decide to be a part of, posting information about you has become an issue of concern. What are those concerns? I mean what is the big deal about privacy? Social networking seems to be the new fad of the century. From Myspace, to Friendster, to Facebook, to Twitter- more and more of us flock to these sites to see what’s going on around us. But a lot of us are unaware of the privacy issues that come along with logging and posting onto these sites- such as me. I didn’t really see how serious privacy issues were until I took this course and read the many articles regarding the many privacy concerns of using social media sites; such as where you’ve been, what you’re listening to, what you’re interests are, who you’re associated with, when you’re not home, where you live or work, what your family looks like, etc. When it comes to these sites, there’s no such thing as privacy. You register your personal information and it’s permanently embedded into the internet. I’ve been a victim of social media. I’ve posted things on the internet that I wish I hadn’t and till this day, I have things on the internet that I just can’t seem to delete. I have certain things on my Facebook that I don’t want to world to see but keeping everything personal and private to just a certain group of people is almost impossible when it comes to social media.

JC Penney Advertising Essay

As time progresses, the world, in terms of business is rather contracting. There is growing communication, interaction and exchange between different parts of the world. Technologies that were once thought of as a far sighted notion are now being used like household commodities and communication mediums that were once considered luxuries available to few are now necessities needed to prosper. And as the world is becoming more integrated and countries are becoming more and more dependent on one another in terms of trade and business the concept of branding, advertising and promotion is becoming more prevalent and widespread. This paper will focus on the marketing of JC penny. It would elaborate on the print as well as online marketing. Moreover it would compare and contrast advertising of online and bricks and mortar companies. Discussion The demand for accountability of marketing is rising and also the pressure of having less absolute dollars to work with so there is utmost need to be sharper, more purposeful and more targeted with marketing. JC Penney is a general retail brand that specializes in clothing, accessories and home furnishing. It has been around for decades and has been catering the needs of consumers of all ages and backgrounds. JC Penney’s main target audience at the present times is women as well as youngsters. JC Penney faced criticism for being a brand that accommodated only the high-end and older generation. However, they have been changing their brand image and have been successful in implementing an image that is portraying a more young and trendy vibe. It now focuses on providing products that have the characteristics of being conservative, traditional, modern or trendy. Fundamentally JC Penney has been escalated in the last years is through the fact that it has moved from mass marketing to a more targeted approach. The few reasons for this change is that JC Penney believes that when business is difficult there is a lot greater chance of success with getting the arms around the best customers and increasing frequency share of wallet and trips with the best customers then trying to recruit new customers in tough times that may not shopping the brand. JC Penney has managed to find ways to develop formats that allowed it to get more productivity out the money that is spend. It has also become more targeted in terms of customer selection through becoming much sharper about making sure the right customers get the right format in the right piece. (Fetterman, 2006) JC Penney is one of the brands that hold the significance of being a brick and mortar store as well as an online retailer. Hence, it follows branding through all of the sources of mass media. It publishes magazines and postcards for the promotion of its products. It also advertises it products and offers through newspapers, television ads and online ads. When comparing the online and print media usage it quoted by Mike Boylson the Executive Vice President and Chief Marketing Officer of JC Penney that In the postcard you can deliver more of a sales message, or more of a discount message these postcards may drive the customers online to see the full assortment online where as the larger brand books of JC Penny show a much richer sense of the style that they have and they portray fundamentally completely different messages. The postcard includes the offer and a link to the website to go see the expanded content where as the book itself that goes out shows the product, the customer can then either come in the store or they can go online or place their order on the phone. Direct mail is very important because through versioning and through customer segmentation the company is able to send out more targeted messages that are highly accountable and are also able to track the results in direct mail to a degree that cannot be possible in a lot of the other traditional mass media used by JC Penney. JC Penney has been focusing a great deal over its brand image and has been trying to diversify and broaden its target audience. It has recently changed to a new brand motif; ‘Every day matters’ along with the new tag line, the company has been working on enhancing its customer’s services and the opening of several temporary promotional stores. JC Penney is focusing on increasing the popularity of its brick and mortar stores as well as its online retailing through providing customers with latest offers, discounts and showcasing their product line online for ease of access. Sloan, 2007) As the world is advancing so are the technologies and the ease with which communication is possible among all parts of the world. With the advent of the internet and the upscale increase in its popularity, there has been almost nothing that is not available on the World Wide Web. The phenomenon of e-shopping emerged with the internet. The fact that customers could get what they want in the ease of their homes, increased the recognition of the internet and also of online shopping. There are numerous differences and similarities between online shopping and traditional shopping. But what holds more importance is the way the companies market their product online and how different it is from the marketing and promotion of brick and mortar companies. (Lowrey, 2008) Marketing over the internet is considered less costly, as it is holds a lower cost of distributing information on a global platform. More and more business are moving towards online retailing due to its outnumbered advantages in terms of cost, convenience and mobility of information over a great distance. One of the major focuses that companies including JC Penney is on the website. The success of online marketing is highly dependent over the outlook, design and the information provided by the website. Both the online companies as well as brick and mortar companies need to identify their target audience before they implement any marketing strategies. This lets them focus on the type of marketing tool they would benefit them. Brick and mortar companies offer a more traditional aspect of shopping and they also follow a traditional approach of marketing. This is mostly through mass media such as newspapers, television broadcast and magazines. With the passage of time, there are less and less companies that focus solely over brick and mortar business. Most companies are now available online as there is less overheads and larger audience prone to response through the internet. Conclusion In the end it is imperative to recognize the increasing importance of internet in business. Both, online retailing and brick and mortar companies hold their own set of characteristics that make them distinct. As the progress of online shopping is increasing there is still need for brick and mortar stores for traditional shoppers. Most companies, however, imply both the alternatives and hence, carry out their marketing accordingly.

Compare and Contrast: Byzantine Empire and the Aztecs Essay

The early civilizations of the byzantine and Aztec empires rose to power using a variety of tactics. They were both very successful and very powerful up to a certain point. The byzantine and Aztec empires both used military strategies and advancements in war. Although while the Byzantine Empire used Christianity to unify its people, the Aztecs made people fear them by using human sacrifices. Also the byzantine was a bureaucracy with an emperor who was thought of to be chosen by the gods to rule over the people, however, the Aztecs had a ruler who was seen as an actual god. The Byzantine and Aztec empires had very strong military tactics which led to expansion and advancement. The Byzantine conquered almost all of the land around it and had many skilled warriors. This is much like the Aztecs who had skilled warriors and even though they didn’t necessarily conquer the land, they took control of the people and made them pay tribute. The Aztecs captured people for human sacrifices many times and this was an adapted technique they used, while the Byzantine used the technique of the â€Å"Greek fire† which was an invention similar to a flamethrower. In the Byzantine Empire there was a main religion and in the Aztec empire hey were highly reliant on human sacrifice to scare people into joining the civilization. The Byzantine empire used the newly found religion of Christianity to unify its population and make them a whole. The Aztecs however, believed in multiple gods and used human sacrifices to make other people fear and respect them. This tactic was also used to get them to join and scared them into paying tribute to the Aztecs or the Aztec gods. There was an emperor in the Byzantine Empire who had much influence because people thought he had been chosen by god; this was similar but not exactly the same as the Aztecs who had a leader that was thought of as an actual deity, or god. Because the Byzantine ruler was thought to be chosen by god, he had power and control over his own civilization and also those that he tried to conquer. The Aztec leader had divine power over his people and since everyone viewed him as a god it would be wrong to defy him. For this reason, he had influence and power over other places, as well as his own.
