University 40-21 A #4H (API 42-495-32611) is a horizontal well in Winkler County operated by Continental Resources Inc., completed March 18, 1997 and listed as shut in on the RRC schedule, shut in August 1, 2022.

The RRC has issued one drilling permit (amended once), issued November 12, 1996, permitted to 8,559 ft.

It was permitted by Texaco E & P Inc. and has since transferred to Continental Resources Inc. on the wellbore schedule.

Completion filings report 2 formation tops, including Delaware, Cherry Canyon.

Its lease has reported 515K barrels of oil and 648K mcf of gas since April 1996, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
