Andrews County · M.F.E. (Grayburg) field · Injection · Vertical
Mfe Unit #321 (API 42-003-36999) is a well in Andrews County operated by Fasken Oil And Ranch Ltd., completed February 20, 1992 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 4, 1991, permitted to 5,103 ft.
It was permitted by Kerr-Mcgee Corporation and has since transferred to Fasken Oil And Ranch Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including Santa Rosa, Rustler, Yates, Grayburg.
Its lease has reported 4.19M barrels of oil and 835K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 52 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 61K barrels injected in the 12 months reported through February 2026.
