The RRC has issued one drilling permit, issued August 2, 1985, permitted to 3,300 ft.
It was permitted by Petroleum Equities Corp. and has since transferred to Riata Energy Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Grayburg, San Andres, Tubb, Clear Fork.
Its 2 leases have reported 5.86K barrels of oil and 192K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
