University 13 35 #31 (API 42-003-46457) is a well in Andrews County operated by Montare Operating Ltd., completed November 30, 2014 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued July 10, 2014, 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 10 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 560K barrels of oil and 142K mcf of gas since November 2012, last reporting in July 2026. The lease carries 30 wells, so these are lease totals, not this well alone.
