It was permitted by Ricks Exploration CO. and has since transferred to Rio Petroleum Inc. on the wellbore schedule.

Its 2 leases have reported 216K barrels of oil and 96.9K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
