| (1) | \epsilon_f = s_w \cdot \epsilon_w(T) + s_o \cdot \epsilon_o(T) + s_g \cdot \epsilon_g(T) |
where
s_w, \, s_o, \, s_g | volumetric fractions of water, oil and gas phases: s_w + s_o + s_g = 1 |
\epsilon_w(T), \, \epsilon_o(T), \, \epsilon_g(T) | relative dielectric permittivity of water, oil and gas phases |
T | fluid temperature |
