This paper is devoted to a new numerical simulation
of two-phases incompressible fluid flow (2D and 3D). Velocity and
pressure equations are solved by an hybrid dual finite element method
(FEM) with suppression of the grid effect. A Van Leer upwind scheme is
used for the saturation equation, in order to reduce the front
dispersion. For equal computational cost this method is more accurate
than the classical finite difference method (FDM) used in reservoir
