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.

Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.

Enhanced by many photographic illustrations of extraordinaryquality, this textbook will provide students with a completeintroduction to the scientific study of environments dominated by snowand ice. Glacial environments are scenically and scientifically amongthe most exciting on Earth, and at the same time they are among themost complex. Apart from the processes associated directly with movingice, other processes -- fluvial, acolian, lacustrine, and marine --frequently interact with ice. Glacial environments therefore exhibit awide variety of landforms and sediment associations. Today, some ten per cent of the land surface of the Earth is coveredby ice, whereas in the Pleistocene the figure exceeded thirty per cent.In earlier geological history, the Earth underwent glaciations ofcontinent-wide extent on several occasions, some of them even moreintense than those of the Pleistocene. By examining the processesoperating within glacial settings and their resulting products,Glacial Environments provides the foundation for investigationof both the ancient and the modern record. Emphasizing the range of erosional and depositional landforms,drawing on the older geological record, according due attention to theexciting recent developments in research on the marine environment,incorporating illustrations from both contemporary and ancientenvironments and covering all relevant parts of the world, thisattractive book will find a wide readership among students ofgeography, geology and environmental science.
