ABSTRACT:
The apparatus allows mixing of a solid and a fluid continuously to facilitate downhole operations, especially gravel packing. The apparatus comprises a solids hopper, with preferably an internal auger, to meter the solids flowrate. The solids drop into a second feeder which empties into a mixing chamber. Liquid can be directed into an annular space formed in the mixing chamber around the periphery of the second auger, or could be piped into the second auger itself. A triplex pump is connected to the mixing chamber and draws the mixed solid and fluid and pumps it to sufficient pressures for use in a wellbore.
