The RRC has issued one drilling permit, issued November 5, 1979, permitted to 4,600 ft.
It was permitted by R & R Production and has since transferred to Brown Darryl Operating L.L.C. on the wellbore schedule.
Completion filings report 2 formation tops, including Kisinger, Strawn.
Its lease has reported 198 barrels of oil since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
