Upton County · Spraberry (Trend Area) field · Producing · Horizontal
University 3-35 #1HB (API 42-461-40088) is a horizontal well in Upton County operated by Civitas Permian Operating LLC, completed July 21, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 15, 2015, permitted to 8,416 ft.
It was permitted by Hunt Oil Company and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Yates, Grayburg, San Andres, Spraberry.
Its lease has reported 2.06M barrels of oil and 5.49M mcf of gas since July 2015, last reporting volume in March 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 20, 2018. Cement bond. 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.
