About Jeff Dravis

Jeff Dravis is a consultant in Carbonate Sedimentology and Marine Geology, primarily focused on searching for oil and gas deposits, or helping to develop them once they are discovered.

Jeff's academic training in geology was purposely designed to gain experience with both modern environments and processes and ancient sedimentary sequences. He received his BS degree in Geology from St. Mary's University San Antonio, Texas, in 1971. He received a Master of Science degree in Marine Geology from the University of Miami's Rosenstiel School of Marine and Atmospheric Sciences in 1977. Dr. Harold R. Wanless was his thesis supervisor. His thesis was entitled "Holocene Sedimentary Depositional Environments on Eleuthera Bank, Bahamas."

In the summer of 1976, Jeff entered Rice University to begin work under Dr. James Lee Wilson on ancient deep-water carbonates. In 1980, he was awarded a Ph D from Rice University, Houston, Texas. His dissertation was entitled " Sedimentology and Diagenesis of the Upper Cretaceous Austin Chalk Formation, South Texas and Northern Mexico."

In 1978, Jeff began his professional career with Exxon Production Research Company in Houston where he conducted applied research on carbonate facies, diagenesis and porosity evolution, and headed up Exxon's worldwide training efforts in carbonates.

In 1986, he started his own consulting practice in Houston. In 1988, he founded Dravis Interests, Inc. to provide technical expertise and training in applied carbonate petroleum geology to the oil and gas industry. In May of 2000, Dravis Geological Services was created to handle all technical consulting projects; Dravis Interests, Inc. is now responsible for all training activities. Jeff has been involved in technical projects worldwide, working in sequences ranging in age from Cambrian to Tertiary. He has presented over 183 applied seminars. His clients are domestic and foreign oil companies, both majors and independents.

Jeff has been an adjunct Professor of Geology at both Rice University and the University of Miami, Florida, since 1987. He teaches at both schools, takes students into the field, and periodically serves on thesis committees.

On a personal note, Jeff has been married for 39 years to Evelyn Parks, an early childhood educator. They have two children: Christopher, who graduated from the University of Pennsylvania in Philadelphia, completed his doctorate in molecular biology at the University of Texas Medical School in Dallas, and is doing post-doctoral studies at the Salk Institute in La Jolla, California; and Elizabeth, who graduated from Rice University in Houston in 2006, obtained a MS in Public Health from the University of Texas, and now works at Methodist Hospital in Houston.

Jeff is an avid golfer and plays in a men's senior baseball league in Houston, as well as in national and regional tournaments. He was a member of the Houston Colt .45s team that won the Caribbean Winter Baseball Championship in Puerto Rico in February, 1999. In November 2001, the Colt .45s won the Masters AAA Division of the Roy Hobbs World Series in Ft. Myers, Florida. In 2004, the Colts also won the MSBL Labor Day Tournament in San Antonio. Since then, they have won national titles in 2007 and 2009.  The Colts also won the regional Men’s Senior Baseball league Labor Day Tournament in San Antonio in 2004, 2008, 2009 and 2010.
