The RRC has issued one drilling permit, issued November 14, 2014, permitted to 11,500 ft.
It was permitted by W&T Offshore, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 4.56M barrels of oil and 6.58M mcf of gas since September 2010, last reporting in July 2026. The lease carries 26 wells, so these are lease totals, not this well alone.
