Abstract:
The present disclosure provides an expansion assembly for setting a liner hanger into mating engagement with an interior surface of a wellbore casing. In one embodiment, the expansion assembly comprises a cone mandrel and an expanding cone assembly positioned adjacent the cone mandrel. The expanding cone assembly includes a plurality of sections, the plurality of sections positioned adjacent each other, each separable by a space S, and together forming an annular ring. The plurality of sections are configured to expand radially outward to a first outer diameter when subjected to a linear downhole force when moving downhole and to contract radially inward to a second smaller outer diameter when moving uphole.
