It was permitted by Austra-Tex Oil Company and has since transferred to Magnum Oilfield Services LLC on the wellbore schedule.

Its 3 leases have reported 153K barrels of oil and 98 mcf of gas since January 1993, last reporting in July 2026. The leases carry 68 wells, so these are lease totals, not this well alone.
