The process of fluid components exchange between phases to reach chemical equilibrium so that total mass of individual components spread between phases according to ambient pressure and temperature . |
The quantitative measure of exchange is given by cross-phase exchange coefficients.
The most popular cross-phase exchange coefficients are Solution GOR and Vaporized Oil Ratio
