Saturated Oil Viscosity(μo,s)
Dynamic or absolute viscosity is defined as resistance to flow exerted by a fluid. It is a measure of the magnitude of internal friction between fluid layers as they move relative to each other.
The viscosity of oil records a minimum value at the bubble point. With the continued depletion of reservoir pressure and the release of free gas, the reservoir oil becomes heavier (i.e., more viscous) due to loss of lighter components to the free gas.
