The RRC has issued 3 drilling permits between 1997 and 2009, permitted to 5,760 ft.
It was permitted by Formation Resources LLC and has since transferred to Initial Energy Services LLC on the wellbore schedule.

Its 3 leases have reported 91.2K barrels of oil and 539K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
