The RRC has issued one drilling permit (amended once), issued January 31, 2023, permitted to 10,500 ft.
It was permitted by Vital Energy, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 619K barrels of oil and 1.79M mcf of gas since May 2023, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
