Abstract The purpose of this memoir is to provide a practical reference for geologists, geophysicists, engineers, and students to gain a better understanding of the various state-of-the-art techniques and applications of electron microscopy for shale hydrocarbon reservoir evaluation. This reference volume is intended for both specialists and non-specialists alike and will serve as a practical guide for petrographic interpretation and reservoir analog studies. This book contains 13 highly illustrated peer-reviewed papers that describe modern techniques and recent case studies, and a catalog of nearly 250 described SEM images of known productive and potential shale hydrocarbon reservoirs in the United States. The included DVD contains a digital copy of the printed material, plus supplemental supporting data, additional color images, and digital reservoir model three-dimensional animation files.
