Glasscock County · Spraberry (Trend Area) field · Shut In · Vertical
Calverley 24a #6 (API 42-173-31738) is a well in Glasscock County operated by Diamondback E&P LLC, completed August 2, 2002 and listed as shut in on the RRC schedule, shut in September 1, 2016.
The RRC has issued one drilling permit, issued November 8, 1984, permitted to 8,016 ft.
It was permitted by Diamond Shamrock Exploration CO. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, Spraberry, T/Reef, Dean.
Its 2 leases have reported 350K barrels of oil and 962K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
