Empirical relationships between the formation resistivity factor F, porosity f, water saturation Sw , and resistivities in clean granular rocks.
where
m = porosity exponent,
Ro = resistivity of the formation when 100%
saturated with formation water,
Rw = formation water resistivity,
Rt = true resistivity of the formation,
n = saturation exponent.
