University 7-26 #5 (API 42-317-35851) is a well in Martin County operated by Diamondback E&P LLC, completed July 15, 2010 and listed as shut in on the RRC schedule, shut in December 1, 2020.
The RRC has issued one drilling permit, issued February 12, 2010, permitted to 10,365 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report one formation top, including See Attached List.
Its lease has reported 199K barrels of oil and 460K mcf of gas since November 2007, last reporting volume in August 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
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
2 logs loaded from the RRC's log index, the latest received Apr 15, 2013. 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.
