The RRC has issued one drilling permit, issued December 8, 1987, permitted to 4,100 ft.
It was permitted by Citation Oil & Gas Corp. and has since transferred to Millwee Oil Inc. on the wellbore schedule.

Its lease has reported 183K barrels of oil and 3.28K mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
