The RRC has issued one drilling permit, issued August 23, 1978, permitted to 8,800 ft.
It was permitted by Continental Oil Company and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Its 3 leases have reported 39.2M barrels of oil and 144M mcf of gas since January 1993, last reporting in July 2026. The leases carry 905 wells, so these are lease totals, not this well alone.
