Abstract
Disclosed is an apparatus and method for shearing well drilling fluid mixtures containing an emulsifier, and utilizing pumping the fluids through a plurality of nozzles, reducing the size of the fluid droplets as they pass through the nozzles, discharging the fluid droplets into a output chamber where the emulsifier surrounds the smaller droplets with the nozzle discharges aligned to intersect in the stabilization chamber.
