MULTICOMPONENT GAS OIL DISPLACEMENTS Whether or not tie line rarefactions appear in a displacement can be determined easily from the placement on the vapor side or the liquid side of the two-phase region and concavity of envelope curves. Once the key tie lines are determined for a given pair of injection gas and oil compositions the full solution for a gas displacement can be determined relatively easily. Effects of volume
