The RRC has issued 2 drilling permits between 2005 and 2009, permitted to 4,800 ft.
It was permitted by OK Arena Operating Company and has since transferred to Montare Operating Ltd. on the wellbore schedule.

Its 2 leases have reported 188K barrels of oil and 164K mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
