It was permitted by Zaza Energy, LLC and has since transferred to Verdun Oil & Gas LLC on the wellbore schedule.

Its 2 leases have reported 251K barrels of oil and 1.4M mcf of gas since November 2011, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
