Abstract
A pressure intensifier and method of increasing fluid pressure at a desired location in a well bore. A central mandrel having a bore therethrough is affixed in a string. Surrounding the mandrel is a cylindrical body having stacked pistons. At a predetermined fluid pressure through the bore, the pistons release and are moved downwards, to integrate pressure across the pistons and act on a chamber pre-filled with application fluid. The application fluid is forced through delivery conduits at a higher pressure than the predetermined fluid pressure and may be used to morph a tubular. In an embodiment, the predetermined fluid pressure is field adjustable.
