The RRC has issued one drilling permit (amended once), issued October 7, 1986, permitted to 3,500 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Sandridge Energy Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Base Cretaceous (marker), Caballos, Ordovician.
Its 2 leases have reported 8.63K barrels of oil and 14K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
