Abstract

The present invention generally relates to a swage assembly that is movable from a compliant configuration having a first shape to a substantially non-compliant configuration having a second shape. In one aspect, an expansion swage for expanding a wellbore tubular is provided. The expansion swage includes a body and a solid cone disposed on the body. The expansion swage further includes a deformable cone disposed on the body, wherein the solid cone is made from a first material and the deformable cone is made from a second material and wherein the deformable cone is movable relative to the body when the expansion swage is in a compliant configuration. In another aspect, a method of expanding a wellbore tubular is provided.

First claim

The invention claimed is:

1. An expansion swage for expanding a tubular, comprising:
an inner mandrel;
a compliant member coupled to the inner mandrel; and
a plurality of cone segments coupled to the compliant member,
wherein the cone segments are configured to expand the tubular, wherein adjacent cone segments are separated by a gap that extends along a longitudinal length of the adjacent cone segments such that each end of each cone segment is separate from each end of eac…
