The RRC has issued 2 drilling permits between 2002 and 2003, permitted to 7,250 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Urban Oil & Gas Group LLC on the wellbore schedule.

Its 2 leases have reported 422K mcf of gas since January 2003, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
