Elrod 4 #5 (API 42-317-35470) is a well in Martin County operated by Diamondback E&P LLC, completed May 24, 2009 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 2008 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 8 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 133K barrels of oil and 214K mcf of gas since April 1999, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
