The RRC has issued 2 drilling permits between 1982 and 1990, permitted to 8,550 ft.
It was permitted by Tex/Con Oil & Gas Company and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Clear Fork, Top Clkfk, Spraberry, Top Upr. Sprby.
Its 3 leases have reported 39.2M barrels of oil and 144M mcf of gas since January 1993, last reporting in July 2026. The leases carry 913 wells, so these are lease totals, not this well alone.
