Abstract:
1. An apparatus for radially expanding and plastically deforming an expandable tubular member, comprising: a resilient launcher comprising a launcher portion and a sleeve portion, wherein an inner diameter of the sleeve portion is smaller than an inner diameter of the launcher portion; an expansion cone coupled to a support member and disposed in the launcher portion of the resilient launcher, wherein the support member and expansion cone include a conduit for supplying fluid to the launcher portion of the resilient launcher; an expandable tubular disposed around the sleeve portion and above the launcher portion of the resilient launcher; a port disposed in the launcher portion of the resilient launcher, wherein the port is closed so that fluid supplied through the support member and the expansion cone drives the expansion cone through the sleeve portion or the resilient launcher so as to radially expand the expandable tubular; and an expansion cone catcher disposed in the sleeve portion above the expandable tubular and operable to prevent upward movement of the expansion cone relative to the resilient launcher.
