The RRC has issued one drilling permit, issued September 12, 2011, permitted to 13,600 ft.
It was permitted by Plains Exploration & Prod. CO. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Its 2 leases have reported 1.56M barrels of oil and 5.63M mcf of gas since June 2011, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
