It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 164K barrels of oil and 873K mcf of gas since December 2011, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
