volumetric fractions of water, oil and gas phases:
\sigma_f = s_w \cdot \sigma_w(T) + s_o \cdot \sigma_o(T) + s_g \cdot \sigma_g(T) |
where
volumetric fractions of water, oil and gas phases: | |
| electrical conductivity of water, oil and gas phases | |
| fluid temperature |
In many practical applications the electrical conductivity of hydrocarbons is much less than that of produced water so that
can be approximated as:
\sigma_f \approx s_w \cdot \sigma_w(T) |
Fluid Resistivity of the miltiphase fluid mix can be found as:
\rho_f = \sigma_f^{-1} |
