Andrews County · Spraberry (Trend Area) field · Shut In · Vertical
University 7-10 B #1 (API 42-003-40235) is a well in Andrews County operated by Diamondback E&P LLC, completed October 8, 2007 and listed as shut in on the RRC schedule, shut in May 1, 2025.
The RRC has issued one drilling permit (amended once), issued August 7, 2007, permitted to 10,300 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 13 formation tops, including Rustler, Tansill, Yates, Seven Rivers.
Its lease has reported 104K barrels of oil and 178K mcf of gas since October 2007, last reporting volume in February 2025. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received May 17, 2011. Density, Neutron, 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.
