The RRC has issued one drilling permit, issued August 25, 1978, permitted to 3,000 ft.
It was permitted by Hughes & Hughes and has since transferred to Cuatro Petro Corp. on the wellbore schedule.
Its 2 leases have reported 4.02K barrels of oil and 806 mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
