The plastic viscosity is the resistance to flow caused by the friction between solid particles. The yield point is the resistance to the initial flow or the stress required to start flowing. The yield point is measured under flowing conditions. Reducing viscosity in any drilling fluid can be achieved by:

What is Plastic Viscosity (PV)? - Definition from ...

Plastic viscosity (PV) can be defined as the resistance offered by a fluid to flow freely. This resistance is a result of friction between the liquid undergoing deformation under shear stress and the solids and liquids present in the drilling mud. PV is a parameter of the Bingham plastic model and is the slope of the shear stress/ shear rate line above the yield point. PV is an important rheological characteristic that …
