It was permitted by Devon Energy Production CO, L.P. and has since transferred to Permian Resources Operating LLC on the wellbore schedule.

Its 3 leases have reported 1.04M barrels of oil and 25.9M mcf of gas since April 2014, last reporting in July 2026. The leases carry 33 wells, so these are lease totals, not this well alone.
