This paper presents the development of a new methodology for relative permeabilities estimation, through the match of the simulation results with the experimental data, obtained from unsteady state displacements. The development of the simulation-optimization tool, in Matlab environment, necessary for the automatic match is presented too. Six unsteady state displacements are performed; four of two-phase and two of three-phase, the experimental data obtained are analyzed using the proposed algorithm. The results from two-phase experiments are compared with those of Sendra software and it is found that the proposed algorithm has a good performance respect to this commercial tool. The results from the three-phase cases show that the algorithm achieves effectively estimate the relative permeability that produce the history match; It is found that there are differences with respect to the estimated curves for two-phase systems.
