Porosity in shale samples is often at such a small scale that analysis with a focused ion-beam scanning electron microscope (FIB-SEM) is needed to resolve the nanometer-size pores in three dimensions. This gain in resolution, however, comes at the expense of analysis volume (typically no more than 1000 um3), which may not be representative of the larger sample. This paper describes a method of creating high-resolution, large-scale SEM images to aid in selecting more representative locations for FIB-SEM imaging and analysis than by current industry practice.

Electron Microscopy of Shale Hydrocarbon Reservoirs
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.
