The RRC has issued 3 drilling permits between 1984 and 1992, permitted to 10,706 ft.

It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Its 3 leases have reported 166K barrels of oil and 2.46M mcf of gas since January 1993, last reporting in May 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
