The RRC has issued 2 drilling permits between 1991 and 1993, permitted to 6,619 ft.
It was permitted by Pennzoil Petroleum Company and has since transferred to Gaither Petroleum Corporation on the wellbore schedule.

Its 2 leases have reported 3.87M barrels of oil and 1.52M mcf of gas since January 1993, last reporting in July 2026. The leases carry 144 wells, so these are lease totals, not this well alone.
