ABSTRACT:
A method of removably anchoring well tubing in a well bore may include selecting a well having a bore diameter and an anchor positioned therein. The anchor may have a housing defining an anchor diameter and extension members extending therefrom toward the bore diameter. The bore diameter and anchor diameter may be spaced apart a distance defining an annulus therebetween and extending along the well. A tool sized to cut substantially exclusively within the annulus may be selected. The tool may be positioned within the annulus, rotated, and advanced to drive past the housing to remove the extension members between the housing and the bore diameter to free the anchor.
