Practical Petroleum Geochemistry For Exploration And Production

Practical Petroleum Geochemistry for Exploration and Production, Second Edition provides readers with a single reference that addresses the principle concepts and applications of petroleum geochemistry used in finding, evaluating, and producing petroleum deposits. The revised volume includes a new chapter on environmental forensic applications of petroleum geochemistry. With the current emphasis on environmental issues (pollution, climate changes, and corporate responsibility), information about how petroleum geochemistry can be used to recognize these problems, determine their source, help identify who is responsible, and how these problems may be mitigated are vital to efficient and economical operation of a project from exploration to production to abandonment. Practical Petroleum Geochemistry for Exploration and Production, Second Edition will continue to serve as a foundational reference to understanding the underpinning of the science, as well as a source of references that the reader can use to find detailed descriptions of methods and protocols. Emphasizes the practical application of geochemistry in solving exploration and production problems Features more than 200 illustrations, tables, diagrams, and case studies to underscore key concepts Authored by an expert geochemist with over 40 years of experience in field-based research, applications, and instruction New edition includes a chapter on environmental issues (impact, climate change, pollution, and corporate responsibility), as well as expanded coverage of topics such as hydrates as unconventional resources; geomicrobial methods (especially DNA analysis) and the use of sea surface slicks from seafloor seeps in surface geochemistry; using GC x GC and asphaltene FTIR in oil correlation studies; and interpretation isotope data for the maturity of thermogenic natural gas

The application of surface geochemical methods to finding petroleum is based on the detection of hydrocarbons in the soil that have leaked from a petroleum reservoir at depth. While the seal over the deposit was once considered impermeable, surface geochemistry data now show that such leakage is a common occurrence. Despite its simplicity and low costs, surface geochemistry remains controversial because, until now, there was no objective and in-depth treatment of the various methods of surface geochemistry for oil exploration. Written by a successful oil finder, this practical guide: * surveys a broad array of surface geochemistry techniques, from soil gases to microbiology, and provides clear strategies for applying them to the high-stakes art of petroleum exploration * offers numerous case studies, both successes and failures, to show the strengths and weaknesses of different approaches * examines statistical and spatial variation, surveys and models in surface geochemistry, demonstrating how each analytical tool can be used to optimize accuracy * integrates surface geochemistry data interpretation with data from conventional methods of oil exploration, and considers the economics of surface geochemical approaches * discusses key topics that have been neglected in the literature, such as grid design and the effects of soils. Geologists, geophysicists, geological engineers and exploration managers involved in petroleum exploration will gain valuable insights from this volume. By presenting and evaluating each method of surface geochemistry in a neutral tone, this book enables the reader to select and employ these methods with greater confidence.

This book is intended primarily as a textbook for geolo gists engaged in petroleum exploration. Its purpose is to introduce the reader to organic geochemistry and to show how to apply geochemistry advantageously in an explora tion program. I have made the explicit assumption that most readers will have a sound background in geology but far less knowledge of, or interest in, chemistry. Be cause there is no need for an exploration geologist to be an expert in organic chemistry, the amount of chemistry used in the book is rather modest. It is, however, often important for a geologist to understand some basic vocab ulary. The emphasis in this book is on applications of geo _chemistry to hydrocarbon exploration. Most of the analyt ical techniques are discussed only briefly, because although a geologist should know what a gas chro matograph is, he or she is unlikely to be asked to repair one. If more detailed knowledge does prove necessary, a laboratory is the proper place to learn. The strengths and weaknesses of the various analytical techniques are discussed so that a geologist will be able to anticipate pitfalls, cull bad data, and choose an appropri ate analytical program. On-the-job experience will prove invaluable in converting the basic information from this text into a practical working knowledge.

This book reviews the present status of organic geochemistry and its application to Petroleum Exploration. It is intended to be as practical as possible with all aspects of geochemistry illustrated by a great number of examples taken from case histories from all over the world which show that geochemistry must be used in the framework of a good geological/geophysical background. This book is written for: petroleum geologists and geophysicists; managers who should integrate the impact of geochemistry in exploration decision-making; specialized geochemists who need an accurate panorama of other aspects of geochemistry; university professors and students in petroleum geology.

This book is an introduction to oil and gas designed to be both accessible to absolute beginners who know nothing about the subject, and at the same time interesting to people who work in one area (such as drilling or seismic exploration) and would like to know about other areas (such as production offshore, or how oil and gas were formed, or what can go wrong). It begins by discussing oil and gas in the broader context of human society, and goes on to examine what they consist of, how and where they were formed, how we find them, how we drill for them and how we measure them. It describes production onshore and offshore, and examines in detail some instructive mishaps, including some that are well known, such as Deepwater Horizon and Piper Alpha, and other lesser known incidents. It looks at recent developments, such as shale oil, and concludes with some speculation about the future. It includes many references for readers who would like to read further. Mathematical content is minimal.

Petroleum Geoscience is a comprehensive introduction to the application of geology and geophysics to the search for and production of oil and gas. Uniquely, this book is structured to reflect the sequential and cyclical processes of exploration, appraisal, development and production. Chapters dedicated to each of these aspects are further illustrated by case histories drawn from the authors' experiences. Petroleum Geoscience has a global and 'geo-temporal' backdrop, drawing examples and case histories from around the world and from petroleum systems ranging in age from late-Pre-Cambrian to Pliocene. In order to show how geoscience is integrated at all levels within the industry, the authors stress throughout the links between geology and geophysics on the one hand, and drilling, reservoir engineering, petrophysics, petroleum engineering, facilities design, and health, safety and the environment on the other. Petroleum Geoscience is designed as a practical guide, with the basic theory augmented by case studies from a wide spread of geographical locations. Covers all the key aspects of the origin of petroleum, exploration, and production. It takes account of the modern emphasis on the efficient utilisation of reserves, on new methods in exploration (such as 3-D seismics). Book takes 'value-chain' approach to Petroleum Geoscience. First new text on petroleum geology for geology undergraduates to be published in the last ten years. Packed full of real-life case studies from Petroleum industry.

A unique presentation of the scope and content of the field of petroleum geology from the standpoint of the practicing petroleum geologist. Includes chapters on basic geological concepts, the sedimentation process, accumulation of hydrocarbons, exploration, economic examination, drilling of exploratory wells, recovering oil and gas (reservoir geology), and the relationship of geology to the petroleum industry as a whole.
