The RRC has issued 3 drilling permits between 1980 and 1991, permitted to 5,400 ft.
It was permitted by Oryx Energy Company and has since transferred to Shell Western E&P on the wellbore schedule.
Completion filings report 3 formation tops, including Queen, Glorieta, Clear Fork.
Its 2 leases have reported 3 barrels of oil since January 1993, last reporting in January 2015. The leases carry 2 wells, so these are lease totals, not this well alone.
