Dynamics Of Oil And Gas Accumulations

Sciences de la terre.

This book presents the authors' research findings on the dynamics of oil migration, research methodologies, insights and applications in petroliferous basins. It studies the behaviors of oil migration in porous media through physical experiments and numerical simulations, explores the mechanism of oil migration and effects of migration process, and then establishes a migration modeling method by coupling the source, driving forces and carriers. The new method can be used to estimate the amount of migrated hydrocarbons and then predict the location of possible hydrocarbon accumulations in different parts of a basin. This approach is useful for resources assessment and prediction of the distribution of hydrocarbon accumulations. An example utilizing this methodology is presented to study the dynamics of migration and accumulation processes in the southern slope of Dongying Depression in Bohai Bay Basin in China. The book appeals to scientists and professionals working on petroleum prospecting as well as faculty and students in petroleum geology.

This monograph presents a wide range of examples showing the different patterns of behavior in permeable aquifers and highlights the interactions between the various elements involved. The author provides a comprehensive investigation of the effects of geometry, permeability, and fluid flow dynamical properties on the ability of an aquifer to retain oil and gas accumulations. With its highly accessible format, each chapter allows for a quick survey of specific factors in the development of hydrocarbon behavior using illustrations. Chapters also feature case histories and examples.

Whether as a textbook for the petroleum engineering student or areference for the veteran engineer working in the field, this newvolume is a valuable asset in the engineer’s library for new,tested methods of more efficient oil and gas exploration andproduction and better estimating methods. In this book, theauthors combine a rigorous, yet easy to understand, approach topetrophysics and how it is applied to petroleum and environmentalengineering to solve multiple problems that the engineer orgeologist faces every day. Useful in the prediction ofeverything from crude oil composition, pore size distribution inreservoir rocks, groundwater contamination, and other types offorecasting, this approach provides engineers and students alikewith a convenient guide to many real-world applications. Fluid dynamics is an extremely important part of the extractionprocess, and petroleum geologists and engineers must have a workingknowledge of fluid dynamics of oil and gas reservoirs in order tofind them and devise the best plan for extraction, before drillingcan begin. This book offers the engineer and geologist afundamental guide for accomplishing these goals, providingmuch-needed calculations and formulas on fluid flow, rockproperties, and many other topics that are encountered everyday. The approach taken in Fluid Dynamics of Oil and GasReservoirs is unique and has not been addressed until now in abook format. Readers now have the ability to review some of themost well-known fields in the world, from the USA to Russiaand Asia. Useful for the veteran engineer or scientist and the studentalike, this book is a must-have for any geologist, engineer, orstudent working in the field of upstream petroleum engineering.

This book discusses the progress that is being made through innovations in instrumental measurements of geologic and geochemical systems and their study using modern mathematical modeling. It covers the systems approach to understanding sedimentary rocks and their role in evolution and containment of subsurface fluids. Fundamental aspects of petroleum geology and geochemistry, generation, migration, accumulation, evaluation and production of hydrocarbons are discussed with worldwide examples. Various physical and chemical properties of subsurface waters, crude oils and natural gases are described which is especially important to production engineering. Among various properties of liquid and gaseous hydrocarbons the most important are wettability affecting production characteristics and ultimate recovery: relative permeability affecting reservoir fluid flow to the production wells; density differences between immiscible fluids which affects gravity drainage; viscosity of subsurface fluids affecting the relative mobility of each fluid; and fluid chemistry, which affects the absorption, ultimate recovery and monetary value of produced hydrocarbons. Discussion of the formation and accumulation of hydrocarbons includes (1) the changes in the chemical composition of hydrocarbons that originate from the debris of living plants and organisms to form crude oil and natural gas; (2) the origin of hydrocarbons in different areas of a single reservoir; (3) the conditions, which determine the distribution of water, oil and gas in the reservoir; (4) the migration of subsurface fluids until they eventually accumulate in isolated traps; (5) discussion of the traps as a function of sedimentary geology and tectonics. This is based on the systems approach to the specific geologic and geochemical systems using analytical and statistical principles and examples of modern mathematical modeling of static and dynamic systems. * Discusses fundamental aspects of petroleum geology and geochemistry, and generation, migration, accumulation, evaluation and production of hydrocarbons * Presents a systems approach to the specific geologic and geochemical systems
