Thermodynamic equilibrium computations are the most time-consuming part of a compositional flow simulation. We describe a compositional space parameterization approach for dealing with gas injection displacement processes. This tie-line-based parameterization can be used to replace existing compositional simulation methods completely. We illustrate our approach using numerical examples of challenging multi-component miscible gas injection problems.
