Mathematical Model

Y_f = F_{\rm cap} \left( \frac{Y_w s_w + Y_o s_o + Y_g s_g}{\mathring{Y}_w} \right)

where 

 – volumetric fractions of water, oil and gas phase (), 

 – are reference values for capacitance of water, oil and gas at given temperature and pressure,

 fresh water capacitance at NTP,

 – non-near function specific to each tool.
