19. A method for setting a hydraulic set packer in a borehole comprising:
applying pressure to a through-tubing pressure intensifier, comprising:
an atmospheric chamber mandrel having a piston area;
an intensifier mandrel having a piston area, the intensifier mandrel connected to the atmospheric chamber mandrel; and
an intensifier chamber, the intensifier chamber being volumetrically reducible to expel a fluid;
capturing wellbore fluid in the intensifier chamber during running; and
changing a pressure at an outlet port disposed in fluid communication with the intensifier chamber relative to an input pressure applied to the intensifier.
