Haddock E. A. #1
Martin County · Spraberry (Trend Area) field · Producing · Vertical
Haddock E. A. #1 (API 42-317-33604) is a well in Martin County operated by Diamondback E&P LLC, completed April 6, 2019 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits (amended once) between 1989 and 2017, 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 10 formation tops, including Spraberry, Dean, Wolfcamp, Pennsylvanian.
Its 2 leases have reported 257K barrels of oil and 242K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
