Abstract:
Apparatus and methods for pressurizing well operations fluids via a pressure exchanger having a housing with a bore extending between first and second ends of the housing and a rotor rotatably disposed within the bore of the housing. A chamber extends through the rotor between first and second ends of the rotor. The chamber has a larger chamber diameter section and a smaller chamber diameter section. A piston assembly is slidably disposed within the chamber. The piston assembly has a larger piston diameter section slidably disposed within the larger chamber diameter section and a smaller piston diameter section slidably disposed within the smaller chamber diameter section.
