It was permitted by Davis Brothers and has since transferred to Kroh Operating LLC on the wellbore schedule.

Its 2 leases have reported 1.42K barrels of oil and 962 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.
