IntroductionRheology is the science of flow and deformation behavior of the matter and the effect of an applied force.Responds with plastic flow rather than elastic.Determines how drilling fluids flow under different conditions.Important for the design of circulation systems. Required to accomplish a certain objectives.Rheological properties are viscosity, gel strength, and yield point.3
Newtonian & Non-Newtonian Fluids4
ViscosityResistance of a fluid to flow.Measured as the ratio of shear stress to the shear rate.Newtonian fluids where the ratio of shear stress to shear rate is constant (water, light oils, etc.).Non-Newtonian where the viscosity is not constant (drilling mud, heavy oils, honey, yogurt).
