Abstract:
An anchoring extrusion limiter for a non-retrievable packer has a plurality of ring segments with a top surface having at least one ring segment insert designed to bite and grip a well casing in which a packer is set. The anchoring extrusion limiter inhibits an extrusion of a main sealing element of the packer while providing anchoring backup to the anchoring slips of the packer.
