Effect of clay on conductivity
Input(s)
\(\mathrm{C}_{\mathrm{w}}\): Conductivity of Water \((1 / \mathrm{ohm} \mathrm{m})\)
F: Formation Factor (unitless)
\(\mathrm{C}_{\mathrm{s}}\): Conductivity due to Salinity \((1 / \mathrm{ohm} \mathrm{m})\)
Output(s)
\(\mathrm{C}_{\mathrm{o}}\): Conductivity of Oil \((1 / \mathrm{ohm} \mathrm{m})\)
Formula(s)
\[
C_{o}=\left(\frac{C_{w}}{F}\right)+C_{s}
\]
