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 illustratedwith 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.

John C. Dolson, Director, DSP Geosciences and Associates, LLC and Senior Geological Advisor, Delonex Energy (London). He has 35+ year’s oil and gas exploration both domestic and international. He has served as Vice President of the American Association of Petroleum Geologists (2006/2007), and was Senior Geological Advisor for TNK-BP (Russia), Amoco/BP before starting DSP Geosciences in 2008. Mr. Dolson has supervised hundreds of geoscientists and has been responsible for prospect generation as well as training and development, with 15 years spent living abroad (Egypt, London, and Moscow). He has served as an adjunct faculty member at the University of Miami (Fla), Colorado State University, Royal Holloway University (London) and geological advisor to Moscow State University and Tyumen State University (Russia). He has an extensive publications list including several landmark papers for AAPG dealing with stratigraphic traps and regional petroleum potential assessmentand has authored books on Black Canyon of the Gunnison National Monument in 1982 and on unconformity analysis with the Rock Mountain Association of Geologists in 1994.
