University 11 Sec. 1 #C 1
Andrews County · Martin (5700) field · Vertical
University 11 Sec. 1 #C 1 (API 42-003-00438) is a well in Andrews County operated by Arco Permian, completed May 23, 1987.
The RRC has issued 3 drilling permits between 1980 and 2002, permitted to 9,100 ft.
It was permitted by BP America Production Company and has since transferred to Arco Permian on the wellbore schedule.
Completion filings report 10 formation tops, including Tansill, Yates, Grayburg, San Andres.
Its 5 leases have reported 786K barrels of oil and 10.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 81K barrels injected in the 12 months reported through February 2026.
Operator of record
Permitted by BP America Production Company; the EWA schedule now lists a different operator.
