Jeffrey J. Dravis (Ph D)

Biography

Jeffrey Dravis is a carbonate geologist with 35 years of experience and owner of Dravis Geological Services, which conducts exploration and reservoir development projects in the U.S., Canada and overseas. He specializes in unravelling the controls on diagenesis and porosity evolution in carbonate sequences that aid in exploiting carbonate reservoirs. He applies innovative petrographic techniques to relate rock-based observations to well logs and seismic data, helping clients better define their subsurface plays and prospects. He has worked numerous carbonate projects in Africa, the Middle East, Southeast Asia and South America, as well as working Jurassic and Cretaceous sequences of the Gulf of Mexico, Devonian and Mississippian in western Canada, and Ordovician-Permian in west Texas and New Mexico. He has consulted for most of the large and smaller independent oil and gas companies in the U.S and Canada.

He is also the president of Dravis Interests, Inc., through which he conducts applied carbonate training seminars for the industry. Since 1987, he has presented well over 200 in-house and field carbonate seminars for industry clients, including over 65 field seminars on Caicos Platform in the southern Bahamas. He received his B.Sc. (geology) from St. Mary’s University in San Antonio, his M.Sc. (Marine Geology) from the University of Miami’s Rosenstiel School of Marine and Atmospheric Sciences, and a Ph.D. (geology) from Rice University, Houston. He worked for Exxon Production Research Company, in Houston, for eight years, before becoming a full-time consultant over 25 years ago. Since 1987, he has been an adjunct professor at Rice, where he teaches part-time and mentors students.
