University 7-1726 #S 04SS (API 42-317-40393) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed June 16, 2016 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued February 9, 2016, permitted to 9,342 ft.

It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 2.97M barrels of oil and 4.91M mcf of gas since August 2015, last reporting volume in April 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Mar 21, 2019. Gamma ray. 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.
