Winkler County · Apollo East (Wolfcamp) field · Temp Abandoned · Vertical
University Blk 21 #261 (API 42-495-30223) is a well in Winkler County operated by TS Oil LLC, completed July 31, 2005 and listed as temp abandoned on the RRC schedule, shut in October 1, 2023.
The RRC has issued 2 drilling permits between 1988 and 2001, permitted to 16,586 ft.
It was permitted by Forest Oil Corp. and has since transferred to TS Oil LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Atoka, Mississippian, Devonian, Fusselman.
Its 3 leases have reported 209K barrels of oil and 3.57M mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
