Ward County · Two Georges (Bone Spring) field · Shut In · Horizontal
University 43-18 #4H (API 42-475-36680) is a horizontal well in Ward County operated by Wpx Energy Permian LLC, completed September 1, 2014 and listed as shut in on the RRC schedule, shut in August 1, 2021.
The RRC has issued one drilling permit, issued March 19, 2014, permitted to 11,115 ft.
It was permitted by Energen Resources Corporation and has since transferred to Wpx Energy Permian LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, San Andres, Yates, Queen.
Its lease has reported 331K barrels of oil and 954K mcf of gas since December 2012, with no volume in the three years through April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Aug 8, 2017. 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.
