University -154- #19 (API 42-003-35972) is a well in Andrews County operated by Highmark Energy Operating LLC, completed August 30, 1988 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits between 1987 and 1988, permitted to 9,950 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 5 formation tops, including Yates, San Andres, Glorieta, Woodford.

Its lease has reported 634K barrels of oil and 602K mcf of gas since January 1993, last reporting in July 2026. The lease carries 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.
