It was permitted by Natural Resource Management Corp and has since transferred to Basa Resources Inc. on the wellbore schedule.

Its lease has reported 732K barrels of oil and 29 mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
