Mustang D #14
Martin County · Lacaff (Spraberry) field · Shut In · Vertical
Mustang D #14 (API 42-317-32908) is a well in Martin County operated by Diamondback E&P LLC, completed September 15, 2005 and listed as shut in on the RRC schedule, shut in November 1, 2025.
The RRC has issued 2 drilling permits (amended twice) between 1984 and 2005, permitted to 10,000 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 Anhydrite, Yates, Clear Fork, Spraberry.
Its 2 leases have reported 39.4K barrels of oil and 127K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
