Abstract
Disclosed is an apparatus for blending sand and solid additives selectively and at selected rates into water for injection into a well. The apparatus may be truck mounted, and includes a frame, an input line with manifold and pump, a mixing tank, a variable venturi nozzle for delivering water to the tank, and an output line with pump, manifold, and recycle line. An auger delivers sand to the mixing tank. Dry chemicals are fed to the tank adjacent the variable venturi nozzle where the water is turbulent, at low pressure, and in high shear. Liquid chemicals may also be pumped into the tank.
