David Grace

He worked successfully to identify, develop, and sell multiple assets in both the Wolfbone in Delaware and the Wolfberry in the Midland Basin. Before ExL, David also worked at Patriot Resources and Piedra Resources. Mr. Grace began his career at Henry Petroleum.

During his tenure at Henry Petroleum, Mr. Grace was an integral part of a team credited by many with the advent of the Wolfberry Play. Prior roles include Senior Geologist and Interim Exploration Manager. In those roles, he drilled and completed more than 600 vertical Wolfberry wells. He is a past President of the WTGS (West Texas Geological Society) and also served on the board of the West Texas Geology Foundation. He is a graduate of Texas Christian University with a B.S. in Geology. David has the magic touch of an oil-finder, and we are excited to have him on the team.
