The Genesis Of Hydrocarbons

Abstrakt Modern petroleum geology is built on the theory of the organic origin of hydrocarbons. It is claimed that they are formed as a result of dipping of organic carbon-rich sedimentary layers and their thermal transformation by which hydrocarbons are generated. Conventional looking at the formation of hydrocarbons is based on buried in a sedimentation pool dead biomass of organisms and their long-lasting microbial degradation in an anaerobic environment with the simultaneous influence of temperature and pressure. This process creates a transformed organic material of high molecular weight called kerogen. About 1% of the live mass of the organic may be stored in kerogen in favorable conditions. Regardless of the type of kerogen, increasing temperature and pressure leads to the dissociation temperature or the cracking and forms a crude oil or natural gas. The secondary cracking at a higher temperature and pressure may result in the smallest particles of hydrocarbons, methane (Sephton, Hazen 2013). This theory does not answer the question of why there are massive accumulations of hydrocarbons reaching hundreds of millions of tons when their hitherto regarded as the mother layers, source rocks, is so little spread in the geological profile?

Analyses data on the composition, structure and formation of various petroleum hydrocarbons: the alkanes, cycloalkanes and arenes. Attention is paid to biological markers, com- pounds that may have preserved the main structural features of the original biogenic molecules. Concepts of chemical classification of crude oils are reviewed with respect to the molecular mass distribution of biological markers, and the genesis and chemical evolution of petroleum hydrocarbons are discussed.

This book demonstrates the direct link between petroleum, the derivative of organic materials, and ore bodies. The studies reported here highlight the common factors between hydrocarbons and mineral concentrations, such as heat sources, migration routes and likely traps. It emphasizes the role that hydrothermal processes play in the genesis of both petroleum generation and ore-grade mineralization. The presence of oil residue in the form of bitumen and pyrobitumen in all sediment-hosted ore bodies throughout the geological record is a testimony to their common diagenetic history. Studies of active hydrothermal systems reported in this book describe the processes and derivatives in these environments, linking hydrocarbon generation and mineral precipitation. A comparison with residual oil in many ore bodies and mineralization occurrences in the geological record, as depicted in this book, can be explained in terms of processes in active hydrothermal systems. One of the most interesting and challenging recent discoveries, that of living nano-bacteria, is reported in this book. The `nanobes', as they have recently been dubbed, have been suggested as the link between the living and non-living matter. The resemblance of these nano-organisms to fossil forms observed in a Martian meteorite have been reported recently in the media. Likewise the similarity to nano-bacteria in Archaean sediments is highlighted in two chapters of the book.

Hydrocarbons provide our core energy resource. Information on their origin, properties and phase behavior is interesting from the point of view of physical chemistry. At the same time this information is of great value to the oil and gas industry. The book "Hydrocarbon" is comprised of 9 chapters, covering different topics: from origin of hydrocarbons to the method for hydrocarbon exploration. Distribution of polycyclic aromatic hydrocarbons in soil and their influence to environment are also discussed. This book should serve as a support to researchers and students as well as experts, both in academia and industry.

Petroleum and natural gas still remain the single biggest resource for energy on earth. Even as alternative and renewable sources are developed, petroleum and natural gas continue to be, by far, the most used and, if engineering properly, the most cost-effective and efficient, source of energy on the planet. Contrary to some beliefs, the industry can, in fact, be sustainable, from an environmental, economic, and resource perspective. Petroleum and natural gas are, after all, natural sources of energy and do not have to be treated as pariahs. This groundbreaking new text describes hydrocarbons in basement formations, how they can be characterized and engineered, and how they can be engineered properly, to best achieve sustainability. Covering the basic theories and the underlying scientific concepts, the authors then go on to explain the best practices and new technologies and processes for utilizing basement formations for the petroleum and natural gas industries. Covering all of the hottest issues in the industry, from oil shale, tar sands, and hydraulic fracturing, this book is a must-have for any engineer working in the industry. This textbook is an excellent resource for petroleum engineering students, reservoir engineers, supervisors & managers, researchers and environmental engineers for planning every aspect of rig operations in the most sustainable, environmentally responsible manner, using the most up-to-date technological advancements in equipment and processes.

Diagenesis is a highly developed, interdisciplinary field of study. It is reciprocal in that it borrows from numerous scientific or technological specialities and then, in turn, repays them with useful results. Too often, however, the information gained and concepts developed remain unintegrated instead of being utilized quickly by several related earth-science fraternities. This volume, the first of a multi-volume work, attempts to bring together such information, thereby assisting the individual and the research group in keeping up with the data explosion. There is no end in sight to diagenetic research because of its wide practical and intellectual appeals. Consequently, periodic reviews, such as presented in this volume, are greatly needed.

Fossil hydrocarbons form a continuous series whose"heavy"members--heavy oils, bitumens, oil shale kerogens, and coal--are important sources of conventional lighter fuels. These hydrocarbons are much more abundant and easier to extract than natural gas and oil. This book discusses the origins and compositions of fossil hydrocarbons and shows how the"heavies"can be chemically transformed into environmentally clean gas, liquid transportation fuels, and an almost unlimited range of petrochemicals. Dr. Berkowitz explodes the entrenched dichotomy between"petroleum hydrocarbons"and coal that has shaped popular perceptions of energy, showing that it is feasible to develop new technologies that capitalize on the availability of"synthetic"natural gas and light oils. Fossil Hydrocarbons: Chemistry and Technology is a comprehensive treatment of fossil hydrocarbons, covering the source materials, biosources, metamorphic histories, geochemistry, classification, and molecular structure. It discusses the use of fossil hydrocarbons as a viable energy source in our future, detailing the preparation, processing and conversion technologies, as well as discussing the environmental issues that arise from production, processing, and use of various fossil hydrocarbons. Approaches various fossil hydrocarbons as chemically related entities, thus dispelling the unwarranted distinctions between crude oils and coal Explains how heavy fossil hydrocarbons can be processed by much the same methods as crude oils for good economic and environmental purpose Illustrates how bitumens, oil shales, and coals are convertible into synthetic natural gas and oils Shows a path for reasonable energy self-sufficiency, through conversion of heavy hydrocarbons into synthetic natural gas and oils Augments each chapter with end-of-chapter notes and a detailed bibliography Provides more than 200 useful tables, schematics, and figures
