Midland County · Spraberry (Trend Area) field · Vertical
Crespi Unit 1 #138 (API 42-329-00239) is a plugged well in Midland County, plugged May 27, 2022, last operated by Diamondback E&P LLC.
The RRC has issued 3 drilling permits (amended twice) between 2009 and 2018, permitted to 12,000 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 6 formation tops, including Spraberry, Strawn, Bend, Atoka.
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.
