Texas University Sec. 1 & 2 #87 (API 42-103-34147) is a well in Crane County operated by Formentera Operations LLC, completed December 7, 1991 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 25, 1991, permitted to 3,400 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Yates, San Andres.

Its lease has reported 1.29M barrels of oil and 651K mcf of gas since January 1993, last reporting in July 2026. The lease carries 73 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.
