oa Introduction of Fractional Molar Flux Curves in the Compositional Equations and their Use in Multi-Component Simulations with Coarse Grid in Heterogeneous Media

Numerical compositional simulation of fully or partially miscible displacements at reservoir scale is known to be adversely affected by severe numerical dispersion arising from the necessity to use coarse grids. Furthermore, fine geological model heterogeneities need to be scaled-up.
