Mathematical Model




\rho_f = \rho_w s_w + \rho_o s_o + \rho_g s_g

where 

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

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

The typical values are:

0.001 g/cc

0.7 – 0.9 g/cc

1.00 – 1.17 g/cc
