Two Phase Z-factor (For Gas Condensates)
The two-phase compressibility factor is introduced to account for liquid drop-out during phase changes (liquid and gaseous phase) in the reservoir.
The two-phase compressibility factor should be used in material-balance calculations for rich-gas-condensate systems.
