Abstract

A downhole anchor mechanism () which can be set on at least two successive standard diameters of casing (). The tool body has a recess into which a split cone () is located. The increased thickness of the split cone () provides for a greater thickness of slip (), giving increased radial travel of the slipswhen moved axially over the split cone (). The cone () and slips () are profiled to provide two ramps/slopes for increased structural integrity and a greater ramp angle to reduce the axial travel of the slips to achieve the increased radial travel. The downhole anchor mechanism () provides anchoring of a work string on two standard diameters of casing in a single trip in a wellbore.
