The RRC has issued one drilling permit, issued June 9, 1992, permitted to 7,300 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Glorieta, Clear Fork, Tubb.
Its lease has reported 19.6M barrels of oil and 7.81M mcf of gas since January 1993, last reporting in July 2026. The lease carries 154 wells, so these are lease totals, not this well alone.
