Calverley 40 #4 (API 42-173-34499) is a well in Glasscock County operated by Crescent Energy Operating LLC, completed November 4, 2011.

The RRC has issued 2 drilling permits (amended once) between 2011 and 2024, permitted to 11,000 ft.

It was permitted by Vital Energy, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Spraberry, Wolfcamp, Lwcmp, Canyon.

Its 2 leases have reported 204K barrels of oil and 832K mcf of gas since December 2010, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
