The RRC has issued 2 drilling permits (amended once) between 1988 and 1993, permitted to 10,000 ft.
It was permitted by Texaco E & P Inc. and has since transferred to Oak Energy LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Frio, Culbertson, Struma, Ammo.
Its 3 leases have reported 8.65K barrels of oil and 116K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
