Abstract
A technique facilitates improved anchoring of expandable well tools along a wellbore or other type of borehole. According to an embodiment, a well tool is sized for placement along a well string. The well tool comprises a tubing and an expandable tubular coupled to the tubing. The expandable tubular is plastically deformable in a radially outward direction when sufficient pressure is applied to an interior of the expandable tubular. The well tool also comprises at least one anchoring ring disposed circumferentially about the expandable tubular. The anchoring ring is constructed with at least one weak point which breaks during expansion of the expandable tubular. Breakage at this weak point enables movement of the anchoring ring in a radially outward direction without elongation of the anchoring ring.
