Biographical Sketch

Jeff Dravis is a carbonate geologist and owner of Dravis Geological Services, and conducts exploration and reservoir development projects in the U.S., Canada and overseas.  He specializes in unraveling the controls on diagenesis and porosity evolution in carbonate sequences that aid in exploiting carbonate reservoirs.  Jeff applies innovative petrographic techniques to relate rock-based observations to well and seismic data, helping clients better define their subsurface plays and prospects.  Most recently, he has been involved with the new oil discovery in the Cretaceous Glen Rose of southwest Texas, the Cretaceous James Limestone around the northern U.S. Gulf of Mexico, and Devonian limestone and dolostone plays in western Canada.  He also has worked carbonate sequences in Africa, the Middle East, Southeast Asia and South America, as well as the Jurassic and Cretaceous of the Gulf of Mexico.

Jeff also is president of Dravis Interests, Inc., through which he conducts applied carbonate training seminars for industry.  Since 1987, he has presented over 100 in-house and field carbonate seminars for industry clients, including dozens of seminars on Caicos Platform in the southern Bahamas.  On Caicos Platform, where trade winds drive carbonate sedimentation, he has helped develop several new alternative models of carbonate deposition, including controls on the distribution of ooid grainstones, and preferential shedding of carbonate sands off the platform and into the adjacent basin.

Jeff received his B.S. (Geology) from St. Mary's University in San Antonio, his M.S. (Marine Geology) from the University of Miami's Rosenstiel School of Marine and Atmospheric Sciences, and 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 17 years ago.

Since 1986, Jeff has been an adjunct professor at Rice, where he teaches part-time and mentors students.
