Dr. Bob Trentham is a Senior Lecturer and Research Associate in Geology. He works with the petroleum industry on applied research and has received over $3,500,000 in grants from the Department of Energy and the Research Partnership to Secure Energy for America to study CO2 and Residual Oil Zones during the past decade. He has added a number of petroleum industry related classes to the graduate and undergraduate geology programs and been advisor on a number of oil related theses. He has obtained numerous private industry donations of oil related data as well as over 30,000' of core for use in the classroom and theses.

Bob had over 20 years of oil industry experience in exploration and production before coming to UTPB in 2001, and he continues to serve on a number of petroleum industry technical boards, including: Annual CO2 Conference, Midland Energy Library, and previously the West Texas Geological Society, Permian Basin Section of the SEPM, and Permian Basin FutureGen Task Force. He received his B.S. and M.A. in Geology from City College of New York and D.G.S. in Geology from the University of Texas at El Paso.

Research Interests

During the past decade, Dr. Bob has focused on industry-sponsored applied research, as well as DOE and RPSEA Grant-funded research on Residual Oil Zones (ROZ). Specifically, he has studied the development of ROZs, strategies to produce oil from ROZ utilizing CO2, and identification of ROZ future potential. He has participated in or directed outcrop and core studies of the producing formations in the Permian Basin, including karsted carbonate oil and gas reservoirs. He is studying the inter-relationship of naturally occurring salt dissolution with production associated dissolution in the development of sinks and sag at the surface and the hydrology of West Texas.
