Gaines County · Flanagan (Clearfork Cons.) field · Injection · Vertical
Flanagan Unit #55W (API 42-165-02508) is a well in Gaines County operated by Hilcorp Energy Company, completed October 1, 2023 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 10, 1991, permitted to 7,208 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Glorieta, Clear Fork.
Its lease has reported 15.9M barrels of oil and 5.02M mcf of gas since January 1993, last reporting in July 2026. The lease carries 220 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 67.8K barrels injected in the 12 months reported through October 2025.
