It was permitted by Hunt Oil Company and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.

Its 3 leases have reported 117K barrels of oil and 904K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
