Crespi Unit 1 #147 (API 42-329-00238) is a well in Midland County operated by Diamondback E&P LLC, completed April 29, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 7, 2015, permitted to 11,370 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its 2 leases have reported 361K barrels of oil and 3.37M mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
