Abstract
Expansion cones and methods of using expansion cones with expandable liner hangers. An example expansion cone includes a detachable support coupled to a mandrel. The detachable support is configured to contact an interior surface of the expandable liner hanger during expansion of the liner hanger. The detachable support is further configured to detach after the liner hanger is expanded thereby producing a detached support. The detached support remains in contact with the interior surface of the expandable liner hanger after expansion of the expandable liner hanger and removal of the mandrel.
