Claim 0:
1. A method for performing a downhole operation, comprising: pumping a hydraulic fluid from a hydraulic pump to an intensifier at a first pressure, wherein the intensifier comprises a hydraulic power section, a piston shaft section and a flow section; translating a piston assembly of the intensifier within both a piston cylinder of the piston shaft section and a hydraulic cylinder of the hydraulic power section based, at least in part, on the hydraulic fluid; drawing a treatment fluid through an inlet port assembly of the flow section into the piston cylinder of the piston shaft section during a suction stroke of the piston assembly; flowing the treatment fluid at a second pressure through an outlet port assembly of the flow section during a discharge stroke of the piston assembly, wherein the second pressure is greater than the first pressure of the hydraulic fluid; stopping pumping of the hydraulic fluid; after stopping pumping, releasing pressure from the hydraulic cylinder via a service return line fluidically coupled to the hydraulic cylinder of the hydraulic power section of the intensifier, wherein the intensifier is coupled to the hydraulic pump; and translating a piston end of the piston assembly, which is disposed in the hydraulic cylinder, to an extended position wherein a piston end shaft of the piston end extends beyond an end wall of the hydraulic cylinder.
