The RRC has issued one drilling permit, issued March 9, 1992, permitted to 7,650 ft.
It was permitted by Glg Energy, L.P. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.

Its lease has reported 1.49M barrels of oil and 426K mcf of gas since January 1993, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
