The RRC has issued one drilling permit, issued November 12, 1987, permitted to 4,850 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Ring Energy Inc. on the wellbore schedule.

Its lease has reported 7.31M barrels of oil and 4.24M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 282 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
