It was permitted by Mlc Operating, LP and has since transferred to Vaquero Operating on the wellbore schedule.

Its 2 leases have reported 190K barrels of oil and 112K mcf of gas since August 2007, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
