The RRC has issued one drilling permit, issued April 28, 2008, permitted to 3,300 ft.

It was permitted by Quantum Resources Management,LLC and has since transferred to Westover Production CO. LLC on the wellbore schedule.

Its lease has reported 1.02M barrels of oil and 773K mcf of gas since July 1996, last reporting in July 2026. The lease carries 96 wells, so these are lease totals, not this well alone.
