University -C- #6 (API 42-003-38720) is a well in Andrews County operated by Highmark Energy Operating LLC, completed April 9, 2002 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 2, 2001, permitted to 10,000 ft.

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

Completion filings report 6 formation tops, including Gloritta, U. Clearfork, Tubb, Wolfcamp.

Its lease has reported 385K barrels of oil and 238K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
