Petroleum Rock Mechanics

Bernt Sigve Aadnøy is a Professor of Petroleum Engineering at the University of Stavanger, specializing in all aspects of well engineering, including geomechanics. He is also an Adjunct Professor at NTNU—the Norwegian University of Science and Technology in Trondheim. He worked for major operators in the oil industry from 1978 until 1994, when he transitioned to academia. Aadnøy has published more than 300 papers, holds 15 patents, and has authored or co-authored seven books, among them Modern Well Design, Petroleum RockMechanics, and Mechanics of Drilling. He was also one of the editors of the SPE book Advanced Drilling and Well Technology (Society of Petroleum Engineers). Aadnøy holds a BS degree in mechanical engineering from the University of Wyoming, an MS in control engineering from the University of Texas, and a PhD in petroleum rock mechanics from the Norwegian Institute of Technology. He was a recipient of the 1999 SPE International Drilling Engineering Award and is also a 2015 SPE/AIME Honorary Member and a 2015 SPE Distinguished Member. He was named SPE Professional of the Year 2018 in Norway. 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.
