The RRC has issued 2 drilling permits (amended once) between 1997 and 2013, permitted to 4,700 ft.
It was permitted by Clear Fork, Incorporated and has since transferred to Enserch Exploration Inc on the wellbore schedule.

Its 4 leases have reported 37.3K barrels of oil and 363K mcf of gas since April 1997, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
