University 32-21 #1 (API 42-495-32615) is a horizontal well in Winkler County operated by Extex Operating Company, completed May 31, 1997 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 1996 and 1997, permitted to 7,600 ft.

It was permitted by Marathon Oil Company and has since transferred to Extex Operating Company on the wellbore schedule.

Completion filings report 4 formation tops, including Ramsey Ss, Cherry Canyon, Manzanita, Brushy Canyon.

Its lease has reported 339K barrels of oil and 159K mcf of gas since February 1997, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
