The RRC has issued 2 drilling permits between 1979 and 2012, permitted to 8,115 ft.
It was permitted by Browning Oil Company, Inc. and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Its 2 leases have reported 141K barrels of oil and 235K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
