Reagan County · Lin (Wolfcamp) field · Producing · Horizontal
University 2a #3H (API 42-383-38477) is a horizontal well in Reagan County operated by Sem Operating Company LLC, completed August 17, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued October 1, 2013, permitted to 8,706 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 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 2.51M barrels of oil and 8.75M mcf of gas since November 2013, last reporting volume in April 2026. The lease carries 13 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 18, 2015. 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.
