Petroleum Rock Mechanics: Drilling Operations and Well Design covers the fundamentals of solid mechanics and petroleum rock mechanics and their application to oil and gas-related drilling operations and well design. More specifically, it examines the role of formation, strength of rock materials, and wellbore mechanics, along with the impact of in-situ stress changes on wellbore and borehole behavior. Practical examples with solutions and a comprehensive glossary of terminologies are provided. Equations are incorporated into well-known failure criteria to predict stresses and to analyze a range of failure scenarios throughout drilling, well operation, and well completion processes. The book also discusses stress and strain components, principal and deviatoric stresses and strains, materials behavior, the theories of elasticity and inelasticity, probabilistic analysis of stress data, the tensile and shear strength of rocks, wellbore stability, and fracture and collapse behavior for both single and multi-lateral wells. Both inexperienced university students and experienced engineers will find this book extremely useful.

Author Biography

Bernt Sigve Aadnoy 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. Reza Looyeh is a registered Chartered Engineer, a Fellow member of the Institute of Mechanical Engineeres (IMechE) in the UK, and a member of the American Society of Mechanical Engineers (ASME). He holds a BSc in Mechanical Engineering from Tehran University, Iran (1989, Honors Degree), an MSc from Newcastle University, UK, in offshore engineering (1994), and PhD from Durham University, UK, in mechanical engineering (1999). He is presently a lead mechanical engineer at Chebron Pembroke Refinery in the UK, a position he has held since 2006. Dr. Looyeh has over 25 technical publications on a variety of topics and is a member of the Engineering Equipment and Material User's Association (EEMUA), Piping Systems Committee (PSC), and Materails Technology Committee (MTC), as well as an industrial advisor to IMechE for the oil and gas sector.
