University San Andres Unit #10 (API 42-003-37201) is a plugged well in Andrews County, plugged October 29, 2024, last operated by Highmark Energy Operating LLC.

The RRC has issued one drilling permit, issued February 5, 1993, permitted to 5,000 ft.

It was permitted by Henry Petroleum Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

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

Its 3 leases have reported 817K barrels of oil and 466K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 75 wells, so these are lease totals, not this well alone.
