The RRC has issued one drilling permit (amended once), issued June 1, 2018, permitted to 4,164 ft.
It was permitted by Endeavor Natural Gas, LP and has since transferred to SM Energy Company on the wellbore schedule.

Its 2 leases have reported 1.35K barrels of oil and 1.77M mcf of gas since September 2018, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
