It was permitted by Mina Energy, Inc. and has since transferred to Samurai Operating CO. L.L.C. on the wellbore schedule.

Its 2 leases have reported 8.15K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
