The RRC has issued one drilling permit, issued May 15, 1980, permitted to 9,000 ft.
It was permitted by Cola Petroleum, Inc. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Its 2 leases have reported 43.8K barrels of oil and 262K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
