University 1801 #20 (API 42-003-45563) is a well in Andrews County operated by Montare Operating Ltd., completed October 6, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 6, 2013, permitted to 5,200 ft.

It was permitted by Sandridge Expl. And Prod., LLC and has since transferred to Montare Operating Ltd. on the wellbore schedule.

Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.

Its lease has reported 515K barrels of oil and 320K mcf of gas since May 2011, last reporting in July 2026. The lease carries 23 wells, so these are lease totals, not this well alone.

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