| \rho_f = \rho_w s_w + \rho_o s_o + \rho_g s_g |
where
\{ s_w, \ s_o, \ s_g \} – volumetric fractions of water, oil and gas phase ( s_w + s_o + s_g = 1),
\{ \rho_w , \ \rho_o , \ \rho_g \} – are reference values for capacitance of water, oil and gas at given temperature and pressure.
The typical values are:
\rho_{\rm gas} | 0.001 g/cc |
|---|---|
\rho_{\rm oil} | 0.7 – 0.9 g/cc |
\rho_{\rm water} | 1.00 – 1.17 g/cc |
