The RRC has issued one drilling permit, issued November 13, 1990, permitted to 10,300 ft.
It was permitted by American Exploration Company and has since transferred to Xto Energy Inc. on the wellbore schedule.

Its lease has reported 96.7K barrels of oil and 926K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
