The RRC has issued one drilling permit, issued November 1, 2013, permitted to 14,000 ft.
It was permitted by Bhp Billiton Pet(Txla OP) CO and has since transferred to Bpx Operating Company on the wellbore schedule.

Its lease has reported 1.39M barrels of oil and 1.95M mcf of gas since August 2012, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
