The RRC has issued 2 drilling permits between 2002 and 2025, permitted to 5,700 ft.
It was permitted by Oakridge Oil And Gas, LP and has since transferred to Western Chief Operating L.L.C. on the wellbore schedule.

Its 2 leases have reported 1.48K barrels of oil since August 2002, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
