University 141a 173 #J 8 (API 42-003-05463) is a well in Andrews County operated by Highmark Energy Operating LLC, completed July 29, 1989 and listed as shut in on the RRC schedule, shut in December 1, 2005.

The RRC has issued 2 drilling permits between 1987 and 1989, permitted to 11,900 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Rustler, Yates, San Andres, Wolfcamp.

Its lease has reported 541K barrels of oil and 315K mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 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.
