It was permitted by Approach Operating LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.

Its 3 leases have reported 1.7M barrels of oil and 19.5M mcf of gas since November 2009, last reporting in July 2026. The leases carry 77 wells, so these are lease totals, not this well alone.
