Vice president-Sections is Tom Ewing, who is recognized for his many outstanding contributions to sorting out the geology of the U.S. Gulf Coast, where he is currently exploring for oil and gas with Yegua Energy Associates. Editor Steve Laubach is senior research scientist with the Texas Bureau of Economic Geology in Austin. Some of his current research includes the emerging field of structural diagenesis, which considers fracture cementation. Secretary Denise Cox is successfully prospecting for oil and gas in the west Texas Permian Basin with her company, Storm Energy of Panama City, Fla. Treasurer Debra Sacrey is a successful Texas Gulf Coast independent/consulting geophysicist/ geologist with the company she founded, Auburn Energy of Houston, Texas. Chair of the House of Delegates is R. Randy Ray, independent geologist in Denver and chief geophysicist for Underground Energy Co. Black swans and various challenges may both come our way this year, but we have a team that’s ready to respond for the good of AAPG.
