The RRC has issued one drilling permit, issued October 2, 1984, permitted to 4,825 ft.

It was permitted by Phillips Oil Company and has since transferred to Conocophillips Company on the wellbore schedule.

Its lease has reported 3.52M barrels of oil and 11.8M mcf of gas since January 1993, last reporting in July 2026. The lease carries 118 wells, so these are lease totals, not this well alone.
