University Lands 31 #1H (API 42-103-35792) is a horizontal well in Crane County operated by Formentera Operations LLC, completed April 12, 2011 and listed as shut in on the RRC schedule, shut in September 1, 2022.

The RRC has issued one drilling permit, issued February 10, 2011, permitted to 3,105 ft.

It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Queen, Grayburg.

Its lease has reported 116K barrels of oil and 267K mcf of gas since April 2011, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
