Here, {\displaystyle \phi \,\!} denotes the porosity, {\displaystyle C_{t}} the electrical conductivity of the fluid saturated rock, {\displaystyle C_{w}}represents the electrical conductivity of the brine, {\displaystyle S_{w}} is the brine saturation, {\displaystyle m} is the cementation exponent of the rock (usually in the range 1.8–2.0 for sandstones), {\displaystyle n} is the saturation exponent (usually close to 2) and {\displaystyle a}is the tortuosity factor.
