Claim:
1. A pressure intensifier for morphing tubulars downhole, the pressure intensifier comprising: an elongate mandrel defining an inner bore, the mandrel being co-axially located within an elongate hollow outer cylindrical body to form a co-axial annular bore therebetween; at least one piston mounted on an outside of the mandrel, each piston having an annular fluid facing face extending substantially across the annular bore; at least one input port to enable fluid communication between the inner bore and the annular bore to act upon each face; at least one stop located on an inner surface of the outer cylindrical body to limit travel of each piston; morph fluid located in the annular bore between an opposing face of a first piston and a first stop; wherein the first stop includes one or more delivery ports extending through said elongate hollow outer cylindrical body to deliver the morph fluid at a greater pressure than the pressure of fluid delivered through the inner bore.
