Abstract:
1. An apparatus for radially expanding and plastically deforming an expandable tubular member, comprising; a tubular support member defining an internal passage and one or more radial passages and comprising internal splines; a tubular expansion cone coupled to the tubular support member comprising an external expansion surface; one or more rupture discs coupled to and positioned within corresponding radial passages of the tubular support member; a tubular stinger defining an internal passage coupled to and positioned within the tubular support member; an expandable tubular member coupled to the expansion surface of the tubular expansion cone comprising a first portion and a second portion, wherein the inside diameter of the first portion is less than the inside diameter of the second portion; a shoe defining one or more internal passages coupled to the second portion of the expandable tubular member; a tubular member coupled to the shoe defining an internal passage comprising a plug seat, one or more upper radial flow ports positioned above the plug seat, and one or more lower radial flow ports positioned below the plug seat, and comprising an external flange for sealingly engaging the interior surface of the expandable tubular member and external splines for engaging the internal splines of the tubular support member, wherein an end of the tubular member receives an end of the tubular stinger and is also received within and sealingly engages and end of the tubular support member; and a tubular sliding sleeve valve received within and sealingly engaging the internal passage of the tubular member defining an internal passage and one or more radial passages and comprising a collet for releasably engaging an end of the tubular stinger.
