ABSTRACT:
An apparatus and a method for expanding a downhole tubular. The apparatus includes a mandrel defining at least one curved support surface. The apparatus further includes an expansion member defining a curved bearing surface for contact with the support surface and corresponding to the mandrel support surface. The expansion member is movable relative to the mandrel, whereby the surfaces are in contact and movable over one another to move the expansion member from a smaller diameter first configuration towards a larger diameter second configuration.
