The RRC has issued 3 drilling permits (amended once) between 1986 and 1992, permitted to 7,850 ft.
It was permitted by Samedan Oil Corporation and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including San Andres, Glorieta, Clear Fork, Wichita-Albany.
Its 3 leases have reported 684K barrels of oil and 37.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 63 wells, so these are lease totals, not this well alone.
