Abstract:
The present invention generally relates to an expandable liner hanger capable of being expanded into a surrounding casing. 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.
