The RRC has issued one drilling permit, issued January 18, 1996, permitted to 13,424 ft.
It was permitted by Umc Petroleum Corporation and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Its 3 leases have reported 306K barrels of oil and 6.28M mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
