Kozeny-carman k-c equation
WebThe Kozeny–Carman (KC) equation generates the low contrast permeability map, while the exponential function of the porosity–permeability relation generates a higher degree of heterogeneity, called the high contrast model. The equations for the models as well as their normalized standard deviations in σ lnk’ are shown in Table 1.
