Elkin 26 #4 (API 42-329-39014) is a well in Midland County operated by Diamondback E&P LLC, completed May 12, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 29, 2014, permitted to 11,201 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 478K barrels of oil and 914K mcf of gas since May 2001, last reporting volume in April 2026. The lease carries 8 wells, so these are lease totals, not this well alone.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
3 logs loaded from the RRC's log index, the latest received Apr 24, 2017. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
