The RRC has issued one drilling permit, issued January 26, 2018, permitted to 10,900 ft.
It was permitted by Encana Oil & Gas(USA) Inc. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Its lease has reported 1.08M barrels of oil and 1.81M mcf of gas since February 2017, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
