Combining term for Solution GOR R_s and Vaporized Oil Ratio R_v ratios in Volatile Oil fluid model which are related to corresponding cross-phase exchange coefficients as:
| (1) | R_s = \frac{\xi_{Go}}{1-\xi_{Go}} \frac{\rho^{\circ}_O}{\rho^{\circ}_G} |
| (2) | R_v = \frac{\xi_{Og} }{1-\xi_{Og} } \frac{\rho^{\circ}_G}{\rho^{\circ}_O} |
