Understanding Oil And Gas Shows And Seals In The Search For Hydrocarbons

This book explains in detail how to use oil and gas show information to find hydrocarbons. It covers the basics of exploration methodologies, drilling and mud systems, cuttings and mud gas show evaluation, fundamental log analysis, the pitfalls of log-calculated water saturations, and a complete overview of the use of pressures to understand traps and migration, hydrodynamics, and seal and reservoir quantification using capillary pressure. Also included are techniques for quickly generating pseudo-capillary pressure curves from simple porosity/permeability data, with examples of how to build spreadsheets in Excel, and a complete treatment of fluid inclusion analysis and fluid inclusion stratigraphy to map migration pathways. In addition, petroleum systems modeling and fundamental source rock geochemistry are discussed in depth, particularly in the context of unconventional source rock evaluation and screening tools for entering new plays. The book is heavily illustrated with numerous examples and case histories from the author’s 37 years of exploration experience. The topics covered in this book will give any young geoscientist a quick start on a successful career and serve as a refresher for the more experienced explorer.

Energy is a key resource for transformational development globally. Oil and gas continue to play a key role in this sector irrespective of the gradual transition towards renewables and will continue to do so in most developing and emerging economies in the near future. The industry is complex and highly capital intensive not only with significant risk, but also with significant benefits. Such a complex but important sector is generally not well understood both in academic and policy circles. This book fills this void by serving as a comprehensive reference to the oil and gas sector, with a focus on emerging markets and developing economies (EMDEs). It offers in-depth coverage of the critical and contemporary issues in the economics of the oil and gas industry by carefully integrating the relevant theoretical underpinnings and practical policy issues across the value chain of the industry in relation to the development, fiscal arrangements, and the economic and financing aspects of the industry. These insights will significantly deepen the understanding of the industry and extend knowledge of the sector in ways that existing books do not. The book includes relevant cases and, thus, will serve as a valuable resource for students taking courses in market analysis of the oil and gas industry, energy economics, development economics and finance, environmental and resource economics, the political economy of the extractive industry, and development studies. Researchers and practitioners working in these areas will also find the book to be a useful reference guide.

A comprehensive account of ore-forming processes, revised and updated The revised second edition of Introduction to Ore-Forming Processes offers a guide to the multiplicity of geological processes that result in the formation of mineral deposits. The second edition has been updated to reflect the most recent developments in the study of metallogeny and earth system science. This second edition contains new information about global tectonic processes and crustal evolution that continues to influence the practice of economic geology and maintains the supply of natural resources in a responsible and sustainable way. The replenishment of depleted natural resources is becoming more difficult and environmentally challenging. There is also a change in the demand for mineral commodities and the concern around the non-sustainable supply of ‘critical metals’ is now an important consideration for planners of the future. The book puts the focus on the responsible custodianship of natural resources and the continuing need for all earth scientists to understand metallogeny and the resource cycle. This new edition: Provides an updated guide to the processes involved in the formation of mineral deposits Offers an overview of magmatic, hydrothermal and sedimentary ore-forming processes Covers the entire range of mineral deposit types, including the fossil fuels and supergene ores Relates metallogeny to global tectonics by examining the distribution of mineral deposits in space and time Contains examples of world famous ore deposits that help to provide context and relevance to the process-oriented descriptions of ore genesis Written for students and professionals alike, Introduction to Ore-Forming Processes offers a revised second edition that puts the focus on the fact that mineral deposits are simply one of the many natural wonders of geological process and evolution.

This richly illustrated book offers a concise overview of the geology of Egypt in the context of the geology of the Arab Region and Northeast Africa. An introductory chapter on history of geological research in Egypt sheds much light on the stages before and after the establishment of Egyptian Geological Survey (the second oldest geological survey worldwide), Hume's book and Said's 1962, 1990 books. The book starts with the Precambrian geology of Egypt, in terms of lithostratigraphy and classifications, structural and tectonic framework, crustal evolution and metamorphic belts. A dedicated chapter discusses the Paleozoic-Mesozoic-Cenozoic tectonics and structural evolution of Egypt. A chapter highlights the Red Sea tectonics and the Gulf of Suez and Gulf of Aqaba Rifts. Subsequent chapters address the Phanerozoic geology from Paleozoic to Quaternary. The Egyptian Impact Crater(s) and Meteorites are dealt with in a separate chapter. The Earth resources in Egypt, including metallic and non-metallic ore deposits, hydrocarbon and water resources, are given much more attention throughout four chapters. The last chapter addresses the seismicity, seismotectonics and neotectonics of Egypt.

The estimation, classification and reporting of oil and gas reserves and related substances has always been a vital part of the oil and gas industry. In spite of a need for consistent methods of reserve determination and terminology, no standardized definitions have really existed.

This reservoir-engineering textbook is a contemporary analysis of primary recovery. It covers rock and fluid properties, reservoir energies, surface separation, laboratory PVT methods, material balance, fluid flow, well deliverability, water influx, reservoir performance, and decline-curve analysis. Using an unified approach, the text includes the full range of reservoir fluids: black oils, volatile oils, gas condensates, wet gases, and dry gases. It also covers the entire range of producing mechanisms, including gas-cap, water-drive, and compaction-drive reservoirs.

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.
