University 1801 #1802 (API 42-003-36950) is a well in Andrews County operated by Montare Operating Ltd., completed August 2, 1991.
The RRC has issued 2 drilling permits between 1991 and 2011, permitted to 4,852 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 Yates, Seven Rivers, Grayburg.
Its 2 leases have reported 588K barrels of oil and 365K mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
