Nolley Wolfcamp Unit #305 (API 42-003-35720) is a plugged well in Andrews County, plugged October 10, 1997, last operated by Crescent Energy Operating LLC.

The RRC has issued one drilling permit, issued January 28, 1987, permitted to 9,700 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 6 formation tops, including Yates, San Andres, Clear Fork, Wichita-Albany.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
