The RRC has issued 3 drilling permits between 1978 and 1986, permitted to 8,899 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Winn Operating LLC on the wellbore schedule.

Its 2 leases have reported 488K barrels of oil and 6.54M mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
