In reservoir simulation, rock properties are given by a geological model defined on a grid made of hundreds of thousands of cells. Performing polyphasic flows directly on this grid may require long computation times. Therefore, reservoir engineers usually build upscaled rock properties on a coarser grid and fluid flow simulations are run with this grid. However, with this approach, the influence of the heterogeneities on the flow may be partially lost. Several multiscale methods have been introduced over the past years to improve the balance between accuracy and computation time. Most of them are dedicated to the resolution of a pressure equation. This equation is first solved on a coarse grid and a reconstruction of both fluxes and the pre...
