... version of Kozeny-Carman equation will require less calibration when it is used to fit the data. Introduction Kozeny-Carman is a semi-empirical model for estimating permeability from porosity (Ø) , specific surface area (S) , grain size (d) , and tortuosity (t) (Carman, 1961). The equation...

... of a rock mass more accurately and reliably with multiple geophysical data based on rock physics (Mavko et al, 2009). The proposed method uses the Kozeny-Carman equation (Carman, 1956) which is widely employed to estimate permeability of granular materials. The porosity and grain size as input parameters...

... porosity with time is monitored to determine the tortuosity of the cores. The NMR derived tortuosity is used, together with the MICP pore-throat size, to predict the matrix permeability using a modified Carman-Kozeny permeability equation. In this report, cores from the unconventional Point-Pleasant...

Up to 1996 the most widely applied technique for permeability modelling in SPDC was a modified form of the Kozeny-Carman equation (Ref.: 1). This model has however been...

... of understanding and proper way to measure tortuosity make it one of the most abused parameters describing transport properties. Hydraulic tortuosity is often treated merely as a fitting factor or, worse, is neglected by combining tortuosity with a geometrical factor in the Kozeny-Carman equation. In this paper...

One of the oldest and most widely used of these is the Kozeny-Carman equation ( Kozeny, 1927 ; Carman, 1937 ), which can be used to estimate the permeability of unconsolidated porous media as a function of porosity and grain diameter. Because porosity is dimensionless...

Thus, permeability estimates from well logs often rely upon porosity, e.g. through the Kozeny Carman equation, which also contains adjustable factors such as the Kozeny...
