University 38 O #1501H (API 42-105-41812) is a horizontal well in Crockett County operated by Sem Operating Company LLC, completed March 1, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued June 18, 2013, permitted to 6,485 ft.

It was permitted by Eog Resources, Inc. 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 183K barrels of oil and 2.8M mcf of gas since February 2014, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
