Andrews County · Shafter Lake N. (San Andres) field · Producing · Vertical
University 1801 #4 (API 42-003-44528) is a well in Andrews County operated by Montare Operating Ltd., completed September 25, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 20, 2012, permitted to 4,985 ft.
It was permitted by Sandridge Expl. And Prod., LLC and has since transferred to Montare Operating Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.
Its lease has reported 515K barrels of oil and 320K mcf of gas since May 2011, last reporting volume in April 2026. The lease carries 23 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Sep 16, 2015. 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.
