<b>Abstract.</b> The Field Mediators Boolean Lattice-Gas Model (MLGA) was used for the dynamical analysis of two-phase immiscible displacement inside bi-dimensional simplified porous structure. Young-Laplace equation is verified from the phase-configuration inside capillary channels, when mechanical equilibrium was reached. The dynamics of the wetting process is analyzed by considering the spreading of a liquid drop in contact with a flat solid surface. Capillary rise under the action of gravity is simulated inside a two-dimensional channels. Simplified two-dimensional geometrical configurations are used for studying imbibition and drainage and the role of trapping in invasion processes and compared with experimental results. The obtained results, apparently, confirm the suitability of MLGA model in the dynamical analysis of immiscible displacement in bi-dimensional porous structure.
