The RRC has issued one drilling permit, issued January 29, 2007, permitted to 10,250 ft.

It was permitted by Exl Petroleum, LP and has since transferred to Saxum Opco LLC on the wellbore schedule.

Its lease has reported 231K barrels of oil and 805K mcf of gas since July 2005, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
