The RRC has issued 2 drilling permits (amended twice) between 2010 and 2011, permitted to 11,900 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Its 3 leases have reported 15.5M barrels of oil and 19.4M mcf of gas since July 2010, last reporting in July 2026. The leases carry 65 wells, so these are lease totals, not this well alone.
