University 38 OR #1401H (API 42-105-42064) is a horizontal well in Crockett County operated by Sem Operating Company LLC, completed November 11, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 24, 2014, permitted to 7,000 ft.

It was permitted by Eog Resources, Inc. and has since transferred to Sem Operating Company LLC on the wellbore schedule.

Completion filings report 8 formation tops, including San Andres, Leonard, Wolfcamp, Canyon.

Its lease has reported 227K barrels of oil and 3.75M mcf of gas since November 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.
