University 09b #1101H (API 42-383-37999) is a horizontal well in Reagan County operated by Sem Operating Company LLC, completed May 30, 2013.

The RRC has issued one drilling permit, issued September 4, 2012, permitted to 8,220 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 2 leases have reported 770K barrels of oil and 2.73M mcf of gas since December 2012, last reporting in July 2026. The leases carry 6 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.
