The RRC has issued one drilling permit, issued August 20, 1984, permitted to 2,300 ft.
It was permitted by Optopco*, Inc. and has since transferred to Reneau Oil CO. on the wellbore schedule.
Completion filings report 5 formation tops, including Blaine, Glorieta, Cimarron Anhydrite, Tubb.
Its lease has reported 9.73K barrels of oil and 32.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
