Understanding Oil and Gas Shows and Seals in the Search for Hydrocarbons

The book covers in detail the ways to differentiate between residual and continuous phase (trapped) oil, false shows and shows associated with source rocks and tight oil and gas reservoirs (potential unconventional targets). Case histories of finding by-p

This book is dedicated to my daughter, Kristin, who legitimately claims ‘I owe her one’, since the last book was dedicated to her brother right before she was born. This book would also not have been possible without the help of my wife, Debbie, who has persevered over the years with my passion for geology, teaching, public service, and a roving expatriate lifestyle. My son, Josh, and his wife Noemi, have introduced to the world to a new grandson (Conrad), who just might think about becoming a geologist someday. I would hope that years from now, he might still have some use for this book, just as I did as a young boy from a textbook my grandfather coauthored, A Study of the Physical World.

Preface

This book is meant for the young geoscientist, but can also serve as a useful reminder for many experienced geoscientists of the need for carefully thinking about hydrocarbon shows in a migration and trap context. The science of petroleum exploration and production evolves at a rapid pace, but some fundamentals will always remain that must be adhered to. Finding oil and gas has never been easy and never risk-free. The techniques and examples in this book should help reinforce the most fundamental need of any petroleum geologist—the ability to understand hydrocarbon shows quantitatively and turn that
