Reagan County · Lin (Wolfcamp) field · Producing · Horizontal
University 27-34 #2LH (API 42-383-38968) is a horizontal well in Reagan County operated by Sem Operating Company LLC, completed December 26, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 11, 2014, permitted to 8,760 ft.
It was permitted by Callon Petroleum Operating CO and has since transferred to Sem Operating Company LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 2.17M barrels of oil and 6.31M mcf of gas since September 2014, last reporting volume in April 2026. The lease carries 13 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 Nov 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.
