Overview

Since the beginning of the US shale gas revolution in 2005, the development of unconventional oil and gas resources has gathered tremendous pace around the world. This book provides a comprehensive overview of the key geologic, geophysical, and engineering principles that govern the development of unconventional reservoirs. The book begins with a detailed characterization of unconventional reservoir rocks: their composition and microstructure, mechanical properties, and the processes controlling fault slip and fluid flow. A discussion of geomechanical principles follows, including the state of stress, pore pressure, and the importance of fractures and faults. After reviewing the fundamentals of horizontal drilling, multi-stage hydraulic fracturing, and stimulation of slip on pre-existing faults, the key factors impacting hydrocarbon production are explored. The final chapters cover environmental impacts and how to mitigate hazards associated with induced seismicity. This text provides an essential overview for students, researchers, and industry professionals interested in unconventional reservoirs.

'Zoback and Kohli's thoughtful and comprehensive examination of the critical role that geomechanics plays in unlocking the potential of unconventional reservoirs is a powerful resource for any engineer or geoscientist working in this arena.' Peter H. Hennings, University of Texas 'In this timely and important book, Zoback and Kohli draw on over ten years of research to describe in detail the full breadth of impact that geomechanics has on unconventional reservoir development. This book will benefit all involved with the fast-moving field of applied geomechanics, providing a good grounding of the basics to those new to the field and new insights to current practitioners.' Steve Willson, Apache Corporation 'This book is sorely needed, long overdue, and should be required reading for both academics and industry professionals working in the unconventional reservoir space. While focused on geomechanics, the book contains information relevant to all aspects of the development of unconventional reservoirs, ranging from basin analysis and sweet spot identification to risk assessment associated with hydraulic fracturing and produced water injection. This book addresses some misconceptions about the mechanical properties of unconventional shales, and challenges common assumptions regarding the variation in horizontal stress as a function of depth. Perhaps most importantly, the book provides practical advice for optimizing the stimulation of unconventional reservoirs.'

Author Information

Mark D. Zoback is the Benjamin M. Page Professor of Geophysics at Stanford University, California. He conducts research on in situ stress, fault mechanics, and reservoir geomechanics with an emphasis on shale gas, tight gas and tight oil production. His first book, Reservoir Geomechanics (Cambridge, 2007) is now in its 15th printing. His online course in reservoir geomechanics has been completed by approximately 10,000 students around the world. Dr Zoback has received a number of awards and honors, including election to the US National Academy of Engineering. Arjun H. Kohli is a Research Scientist and Lecturer in the Department of Geophysics at Stanford University, California. He conducts research on earthquake physics to understand the behavior of plate boundary faults and the occurrence of induced seismicity. He co-developed two massively open online courses on geomechanics, including interactive assignments designed for students with diverse backgrounds ranging from high school to industry professionals.
