University 7-30 #8 (API 42-317-37062) is a well in Martin County operated by Diamondback E&P LLC, completed February 28, 2012 and listed as shut in on the RRC schedule, shut in April 1, 2020.
The RRC has issued one drilling permit, issued July 22, 2011, permitted to 11,175 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including San Andres, Clear Fork, Spraberry, Dean.
Its lease has reported 717K barrels of oil and 2.49M mcf of gas since February 2008, last reporting volume in April 2026. The lease carries 17 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.

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.

W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
3 logs loaded from the RRC's log index, the latest received Jan 12, 2015. Density, Neutron, Resistivity, Sonic. 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.
