The RRC has issued one drilling permit, issued March 16, 1984, permitted to 9,950 ft.
It was permitted by Marshall & Winston, Inc. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.

Its lease has reported 14.4K barrels of oil and 14.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
