EXXON PRODUCTION RESEARCH COMPANY, TEXAS, U.S.A.
July 1981 to July 1994 - Research Associate
Served as Group Leader of the Thin Bed/Shaly Sand Group for seven years.
Initiated a research project on new methods to interpret wireline logs in thinly bedded, shaly sandstone reservoirs, including those in the Malay Basin and Gulf of Mexico. Developed strip core sampling techniques to improve representativeness of core samples in thinly bedded, mineralogically complex reservoirs.
Developed and tested new pulsed neutron capture techniques to monitor oil-water contact movement through casing in marginal salinity environments such as the Gippsland Basin in Australia and Brent field in the North Sea. Developed and applied techniques to quantify oil and gas saturation changes in high salinity environments for enhanced oil recovery projects and performed well-site work for this project.
Conducted research on nuclear magnetic resonance logging. Performed well-site work associated with this research. Primary developer of Exxon’s Cased-Hole Nuclear Logging Course and primary person for updating Exxon’s Basic Well Logging School. Taught the Cased-Hole Nuclear Logging Course and the Basic Well Logging School for Exxon’s world-wide affiliates for over ten years.
Provided advice to all Exxon upstream operating affiliates on designing special logging programs and often provided well-site assistance for these programs.
