For ,drilling fluid, treatment purposes, the Bingham plastic model is superior to other models as it indicates the nature of contamination of the ,drilling fluid, and the required treatment. For instance, an increase in plastic viscosity of the ,fluid, indicates solid contamination, while an increase in yield point suggests chemical contamination.
