Andrews County · Spraberry (Trend Area) field · Shut In · Vertical
University 6-46 #4 (API 42-003-42940) is a well in Andrews County operated by Diamondback E&P LLC, completed July 24, 2014 and listed as shut in on the RRC schedule, shut in October 1, 2026.
The RRC has issued one drilling permit, issued May 16, 2011, permitted to 11,352 ft.
It was permitted by W&T Offshore, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Spraberry, Strawn.
Its lease has reported 373K barrels of oil and 589K mcf of gas since August 2010, last reporting volume in March 2026. The lease carries 6 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 15, 2014. Resistivity. 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.
