The RRC has issued 2 drilling permits (amended once) between 1997 and 2006, permitted to 10,000 ft.
It was permitted by Gilmore, Leo Oil, Inc. and has since transferred to Williams Clayton Energy Inc. on the wellbore schedule.

Its 3 leases have reported 8.44K barrels of oil and 153K mcf of gas since March 1998, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
