✦ Synopsis

This book brings the practice of petroleum geostatistics into a coherent framework, focusing on tools, techniques, examples, and guidance. It emphasizes the interaction between geophysicists, geologists, and engineers. Intended as a reference text for practitioners, the book is also appropriate for "short courses" and advanced undergraduate or graduate courses in reservoir characterization.
