The RRC has issued 2 drilling permits (amended twice) between 2005 and 2011, permitted to 4,250 ft.
It was permitted by Resaca Operating Company and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Its 2 leases have reported 3.52K barrels of oil and 8.99K mcf of gas since October 2005, last reporting in April 2015. The leases carry 2 wells, so these are lease totals, not this well alone.
