Abstract: The present invention generally relates to an expansion swage and an expandable liner. In one aspect, an expandable tubular system is provided. The system includes an expandable tubular. The system further includes an expansion swage for expanding the expandable tubular, wherein the expansion swage is deformable from a compliant configuration to a smaller substantially non-compliant configuration. Additionally, the system includes a restriction member disposed on an exterior surface of the expandable tubular, wherein expansion of the expandable tubular in the location of the restriction member deforms the expansion swage from the compliant configuration to the smaller substantially non-compliant configuration. In another aspect, a method of expanding a liner hanger using a cone is provided. In another aspect, a liner hanger for use in a wellbore is provided. In another aspect, an expansion swage for expanding a wellbore tubular is provided. In another aspect, a method of expanding a wellbore tubular is provided.

Abstract: A deployment assembly for expanding a liner string in a wellbore includes: a tubular mandrel having a bore therethrough; an expander linked to the mandrel and operable between an extended position and a retracted position; an extension tool disposed along the mandrel and operable to extend the expander; and a retraction tool disposed along the mandrel. The retraction tool has: an upper piston in fluid communication with the mandrel bore and operable to retract the expander; a lower piston in fluid communication with the mandrel bore and operable to balance the upper piston; a valve disposed between the pistons for isolating the lower piston from the upper piston in a closed position; and an electronics package linked to the valve for opening and closing the valve in response to receiving a command signal.

Abstract: An expandable tubular assembly includes an expander 190 for expanding a tubular 125. The expander 190 may be hydraulically actuated. A bore obstruction object 206 may be received in a receptacle sleeve 210 that is a modular component of the expandable tubular assembly. In this respect, the expandable tubular assembly may be quickly fitted with a receptacle sleeve 210 designed to receive selected type of bore obstruction object 206.
