It was permitted by Four H Oil Properties and has since transferred to Stamper Operating CO. Inc. on the wellbore schedule.

Its 2 leases have reported 1.9K barrels of oil and 24.6K mcf of gas since June 2012, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
