Abstract
A method of determining one or more minimum rheological properties of a particle laden fluid is disclosed. The method includes determining one or more rheological properties of the fluid at a first shear rate, determining the settling velocity of the particles at the first shear rate, and obtaining a transport index for the fluid, the transport index indicating a relationship between the settling velocity and the one or more rheological properties.
