About ETX Energy

ETX Energy is based in Tulsa, Oklahoma, and owns, manages and operates upstream and midstream energy projects in Southeast Texas, with its activity primarily focused in the Eastern Eagle Ford. ETX is highly experienced in the application of advanced technologies such as horizontal drilling and multi-stage fracture stimulation to maximize the value of U.S. oil and natural gas reserves.


ETX pivoted in mid-2018 to focus primarily on drilling its Eastern Eagle Ford position. ETX follows a technology-driven strategy, combining the expertise of its technical and operating/engineering teams with its extensive 3D seismic inventory to identify and successfully drill its long-term inventory of Eagle Ford prospects. ETX has also applied that strategy to the stacked carbonate play of the Buda, Georgetown, Edwards and Glen Rose formations.

ETX relentlessly pursues increasing efficiencies and lowering costs while maintaining safety as the top priority. Since its formation, ETX has not had a lost time accident (LTA). ETX is laser-focused on increasing returns, which leads to the ultimate goal of increasing value for its shareholders.
