Pecos County · Brown & Thorp (Clear Fork) field · Injection · Vertical
Sullivan Unit #11 (API 42-371-36740) is a disposal or injection well in Pecos County operated by Caroil LLC under an active UIC permit.
The RRC has issued one drilling permit, issued July 22, 1997, permitted to 3,300 ft.
It was permitted by BC Operating, Inc. and has since transferred to Caroil LLC on the wellbore schedule.
Its lease has reported 151K barrels of oil since January 1998, last reporting in July 2026. The lease carries 30 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 1.61K barrels injected in the 12 months reported through May 2025.
Operator of record
Permitted by BC Operating, Inc.; the EWA schedule now lists a different operator.
