Petroleum Rock Mechanics: Drilling Operations and Well Design, Second Edition, keeps petroleum and drilling engineers centrally focused on the basic fundamentals surrounding geomechanics, while also keeping them up-to-speed on the latest issues and practical problems. Updated with new chapters on operations surrounding shale oil, shale gas, and hydraulic fracturing, and with new sections on in-situ stress, drilling design of optimal mud weight, and wellbore instability analysis, this book is an ideal resource. By creating a link between theory with practical problems, this updated edition continues to provide the most recent research and fundamentals critical to today's drilling operations.
- Helps readers grasp the techniques needed to analyze and solve drilling challenges, in particular wellbore instability analysis
- Teaches rock mechanic fundamentals and presents new concepts surrounding sand production and hydraulic fracturing operations
- Includes new case studies and sample problems to practice

Bernt Sigve Aadnøy received the B. Sc. degree in mechanical engineering from the University of Wyoming, USA in 1978, the M. Sc. degree in control engineering from the University of Texas, USA in 1979, and the Ph.D. degree in geomechanics from the Norwegian Institute of Technology, Norway in 1987. He is a professor of petroleum engineering at the University of Stavanger, Norway. He also holds a mechanical engineering degree from Stavanger technology, Norway. Before going to academia, he worked for Phillips Petroleum, Rogaland Research, Statoil and Saga Petroleum. He has published more than 200 papers, mostly on rock mechanics and well technology but also in reservoir engineering, production and automation, and holds 10 patents. He is the author of several books such as Petroleum Rock Mechanics, Second Edition (Elsevier) and is technical editor for several journals. He was the recipient of the SPE (Society of Petroleum Engineers)/AIME (the American institute of Mining and Metallurgical Engineers) Honorary Member, SPE Distinguished Member, and SPE Oil Professional Award.
