The RRC has issued one drilling permit, issued November 14, 1977, permitted to 5,000 ft.
It was permitted by Bass Enterprises Production CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 7.43M barrels of oil and 4.98M mcf of gas since January 1993, last reporting in July 2026. The leases carry 253 wells, so these are lease totals, not this well alone.
