The RRC has issued one drilling permit, issued July 9, 1982, permitted to 4,401 ft.
It was permitted by Cities Service Company and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 1.48M barrels of oil and 585K mcf of gas since January 1993, last reporting in July 2026. The lease carries 131 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
