ABSTRACT:
An apparatus is provided for direct high velocity, consistent, uniform preparation of completion/workover systems for use in subterranean wells. The system has a screw type conveyor extending through a mixing housing which is in direct communication with a pump. Passageways are provided through the housing for the screw type rotatable conveyor and through the mixing chamber housing in axial alignment with openings in the pump such that the diametric area between the interior of the mixing housing and the exterior of the conveyor housing provides sufficient transport velocity for the carrier fluid and the solid particulate matter from the point of mixing in the annulus, through the annulus and to the inlet of the pump.
