Nolley Wolfcamp Unit #507 (API 42-003-35487) is a well in Andrews County operated by Crescent Energy Operating LLC, completed August 23, 2024 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 20, 1986, permitted to 9,600 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 2.24M barrels of oil and 1.52M mcf of gas since January 1993, last reporting in July 2026. The lease carries 67 wells, so these are lease totals, not this well alone.
