Patent ID: 7419009

Claim:
An apparatus for radially expanding and plastically deforming an expandable tubular member, the apparatus comprising: a first tubular support defining an internal passage and one or more radial passages; a tubular expansion cone coupled to the first tubular support and comprising an external expansion surface wherein the tubular expansion cone and the first tubular support are adapted to extend within the expandable tubular member so that the expandable tubular member is coupled to the external expansion surface of the tubular expansion cone; a second tubular support coupled to the first tubular support and defining an internal passage; a third tubular support coupled to the second tubular support so that the third tubular support at least partially extends within the second tubular support; and a fourth tubular support coupled to the second tubular support so that the second tubular support at least partially extends within the fourth tubular support; wherein the tubular expansion cone and the first, second, third and fourth tubular supports are movable relative to the expandable tubular member when the first tubular support and the tubular expansion cone extend within the expandable tubular member.
