The RRC has issued one drilling permit (amended once), issued March 12, 2012, permitted to 13,400 ft.
It was permitted by Burlington Resources O & G CO LP and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 376K barrels of oil and 1.16M mcf of gas since June 2012, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
