Weighting materials are a high-specific gravity and finely divided solid material used to increase the density of a drilling fluid. How to add weighting materials to the drilling fluids?
In most oil & gas drilling solids control system, there are weighting tank, which has a mud hopper and mixing pump, the operator add the additives from the top of the venturi hopper, the mixing pump transferred the drilling fluids through the cross under the hopper, under the working of pressure, the power material are added to the drilling fluids. It will be mixed by mud agitator installed on the tank. Sometimes shear pump will be used instead of centrifugal pump.
