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.

Apparatus for direct high velocity preparation of completion/workover systems incorporating a solid particulate matter into a carrier fluid for use in subterranean wells, comprising: (a) fluid pump means having inlet and outlet members; (b) a conveyor system having: a cylindrical conveyor housing; an elongated rotatable conveyor disposed therethrough; and a circumferentially extending transporting blade axially defined around the outer length of said conveyor; (c) a cylindrical mixing housing secured relative to said pump means; (d) an inlet through said cylindrical mixing housing for receipt of said conveyor housing; (e) first fluid flow passages defined through said cylindrical mixing housing and in fluid communication with the inlet members of the pump means; (f) second fluid flow passages defined through said conveyor housing and in relative axial alignment with said first fluid flow passages; (g) a mixing annulus within the mixing housing and having a diametric area between the interior of said mixing housing and the exterior of said conveyor housing sufficient to provide a transport velocity for the carrier fluid and the solid particulate matter from the point of mixing thereof in the annulus and through said annulus to said inlet member of said pump means; (h) means for transmission and receipt of a carrier fluid through the mixing housing and into the mixing annulus; (i) means for activation of said rotatable conveyor; and (j) means for introduction of particulate matter into said cylindrical conveyor housing upstream of said means for transmission of said carrier fluid.
