Due to the concern about oil’s extraction efficiency decline throughout the time, researchers have looked for alternatives to raise the displacement efficiency of trapped oil within micropores, which has a known complex geometry. The use of numerical simulation presents advantages since it is an economically viable technology with good precision. The current proposition analyzes numerically and with the aid of the Ansys Fluent software, the influence of wettability in microcavity geometry in the displacement of oil by water. Several cases with different radius curvatures of the geometry, contact angles and their influence in displacement efficiency of residual oil are evaluated. The results led to a more realistic analysis regarding the mobilization of trapped oil within the microcavities.
