Porosity Was Measured and Permeability Was Derived From the Measured Capillary Pressure Data. The Resistivity Can Be Scaled as [3 ] −  Ω =  Ω   W Max S Df ............ (1) Where S W Is the Water Saturation, Ω = Resistivity in Ohm Meter. Ω Max = Maximum Resistivity in Ohm Meter. Df = Fractal Dimension. Equation 1 Can Be Proofed From 32 1 11 ** 120  =   Σ  K F ........... (2) Where K = Permeability in Millidarcy (Md). 1/120 Is a Constant F= Formation Electrical Resistivity Factor in Zero Dimension Σ = Quadrature Conductivity in Siemens / Meter but 2 2 1 = Ω Σ ........... (3) Insert Equation 3 Into Equation 2 2 3 11 ** 120  =    F κΩ ............ (4) 2 2 3 11 ** 8* 120  Ι Ω= =    R F F F Κ ....... (5) R in Equation 5 Is the Pore Throat Radius. Equation 5 After Rearrange Will Become 2 32 8* * 120* *  =   F Fr Ω ........... (6) Equation 6 After Simplification Will Result in 2 22 15* *  =   Fr Ω ............
