Meet the SPE Energy Experts

The Society of Petroleum Engineers‘ team of Energy Experts is composed of top engineers and industry specialists. Together, they have contributed to the educational information found throughout this website. Our team includes:

Robert W. Chase

Chase has been a professor and department chair involved with petroleum engineering and geology since 1976. Prior to his academic career, Chase worked for service companies and the US Department of Energy as a consultant. He has written numerous technical papers in the areas of natural gas engineering and well testing. Chase received the C. Drew Stahl Distinguished Achievement Award in Petroleum and Natural Gas Engineering from Pennsylvania State University in 2006. He received the SPE Distinguished Member Award in 1998, the SPE Distinguished Service Award in 2009, and the SPE Distinguished Faculty Award in 2011. He was inducted into the Marietta College Petroleum Engineering and Geology Hall of Fame in 2010 and received an honorary alumnus award from Marietta College in October 2011. He holds BS, MS, and PhD degrees in petroleum and natural gas engineering from Pennsylvania State University. Chase currently serves as a professor and chair of the Department of Petroleum Engineering and Geology at Marietta College.

J. Ford Brett

Brett consults in the area of petroleum project management, and has delivered workshops and short courses in more than 20 countries. He has worked on numerous exploration and development drilling projects in the Bering Sea, North Slope of Alaska, Gulf of Mexico, offshore Trinidad, and the Overthrust Belt in Wyoming. He has been granted more than 25 US patents and is the author or co-author of more than 30 technical publications. For his work on improved oilwell drilling techniques, he was honored in 1996 with a nomination for the National Medal of Technology, the United States’ highest technology award. In 2000, he received the American Society for Competitiveness Philip B. Crosby Medal for Global Competitiveness Through Quality in Knowledge Management, Best Practices Transfer, and Operations Improvement. Brett has served as a Distinguished Lecturer for SPE. He holds a BS degree in mechanical engineering and physics from Duke University (where he was elected to Phi Beta Kappa), an MBA degree from Oklahoma State University, and an MSE degree from Stanford University. Brett currently is the President of PetroSkills.

Norman R. Warpinski

Warpinski is a Chief Technology Officer in charge of developing new tools and analyses for hydraulic fracture mapping, reservoir monitoring, hydraulic fracture design and analysis, and integrated solutions for reservoir development. He worked at Sandia National Laboratories from 1977 to 2005 on projects in oil and gas, geothermal, carbon sequestration, waste repositories, and other geomechanics issues. Warpinski has extensive experience in various types of hydraulic fracture mapping and modeling and has been involved in large-scale field experiments from both the hardware and software sides. He has also worked on formation evaluation, geomechanics, natural fractures, in situ stresses, rock behavior, and rock testing. He received MS and PhD degrees in mechanical engineering from the University of Illinois, Champaign/Urbana, in 1973 and 1977, respectively, after receiving a BS degree in mechanical engineering from Illinois Institute of Technology in 1971. He currently works for Pinnacle Technologies.

John Cramer

Cramer has more than 30 years of industry experience working with service companies as a production engineer responsible for overseeing oil and gas production in Ohio and Michigan. He provides sales and technical support for all aspects of well cementing and completion services. Cramer has written several papers and served on SPE’s International Board of Directors since 2010. He holds a civil engineering degree from Pennsylvania State University. Cramer currently works for Superior Well Services, responsible for both sales and technical efforts in the North Appalachian Region.

George E. King

King is a global technology consultant with more than 40 years of oil field experience. His technical background includes basic research on energized fracturing, production and fracturing chemicals, acidizing, asphaltenes, perforating cleanup, well integrity and completions, complex formations, unconventional resources, sand control, low pressure gas well operations and applications work on coiled tubing, cutoff, formation damage, and well repair operations. Technical accomplishments include 60 technical papers, a book on completions and workovers, Distinguished Lecturer on foam fracturing for SPE during 1985-86, and a Completions Course Lecturer on horizontal wells for the SPE Short Course series in 1999. He maintains a website with free downloads of petroleum engineering educational materials at King holds a BS degree in chemistry from Oklahoma State, 1972; BS degree in chemical engineering from University of Tulsa, 1976; and MS degree in petroleum engineering from the University of Tulsa, 1982. He currently works for Apache Corporation.
