University 40 #1406H (API 42-105-41427) is a plugged horizontal well in Crockett County, plugged June 29, 2022, last operated by Sem Operating Company LLC.

The RRC has issued one drilling permit (amended twice), issued February 24, 2012, permitted to 6,600 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 5.89M barrels of oil and 91.5M mcf of gas since May 2010, last reporting volume in April 2026. The lease carries 64 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.
