Calverley 40a #5NC (API 42-173-36627) is a horizontal well in Glasscock County operated by Crescent Energy Operating LLC, completed November 20, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 24, 2014, permitted to 9,208 ft.
It was permitted by Laredo Petroleum, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Grayburg.
Its lease has reported 163K barrels of oil and 590K mcf of gas since September 2010, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
