University San Andres Unit #28W (API 42-003-38866) is a well in Andrews County operated by Highmark Energy Operating LLC, completed January 28, 2002 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued August 16, 2001, permitted to 4,785 ft.

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

Completion filings report 3 formation tops, including Santa Rosa, Yates, San Andres.

Its lease has reported 743K barrels of oil and 422K mcf of gas since August 2001, last reporting volume in April 2026. The lease carries 44 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 48.3K barrels injected in the 12 months reported through March 2026.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
