The purpose of this work was to investigate the flow of two-phase fluids via the Buckley-Leverett equation, including dispersive and diffusive terms. For this, a weighted essentially non-oscillatory scheme, a Runge-Kutta method and a finite difference scheme were computationally implemented. The use of these methods made it possible to obtain numerical solutions, without excessive numerical dispersion and dissipation, sufficient to assist in the understanding of the mixing profiles of saturated water and petroleum fluids, inside pipelines filled with porous material. In addition, the impact of adding such terms in the original equation has been studied.
