Andrews County · Nolley (Wolfcamp) field · Vertical
Nolley Wolfcamp Unit #508 (API 42-003-35496) is a plugged well in Andrews County, plugged May 24, 2016, last operated by Crescent Energy Operating LLC.
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.
Completion filings report 8 formation tops, including Rustler, Yates, Queen, San Andres.
Its lease has reported 2.24M barrels of oil and 1.52M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 67 wells, so these are lease totals, not this well alone.
