  • Centrifugal blending system
    Patent number: 7353875
    Abstract: The present invention relates generally to well servicing operations, and, more particularly, to devices, systems and methods useful in stimulation blending for fluids, mixtures, and/or slurries used in well servicing operations. A device, system and/or method is provided comprising a suction centrifugal pump capable of receiving an inlet fluid and providing a suction pressure arranged to substantially minimize a geyser effect in a proppant inlet and a mixer capable of receiving the inlet fluid provided by the suction centrifugal pump and mixing the inlet fluid with a proppant received from the proppant inlet, the mixer arranged to be substantially optimized for mixing. The device, system and/or method also comprises a discharge centrifugal pump capable of receiving the inlet fluid mixed with the proppant from the mixer and discharging the inlet fluid mixed with the proppant from the mixer downhole, the discharge centrifugal pump arranged to be substantially optimized for pumping.
