This study aims the description of the geometry of the weathering profile and identification of areas of high aquifer potential of geological formations in the region of Sikensi-Tiassalé (south of Côte d’Ivoire). For this reason, the weathering profile models have been established for this region. These models were carried out from drilling data implanted in the study area. The formations in the basement have a vertical structure and a significant horizontal heterogeneity that is allocated to changes in facies. A succession of several layers is observed. Fractured and altered basement is observed in its upper part. Fractures are scarce with depth. Superficial formations overlying the basement have variable thicknesses: To the surface, there is laterite cuirass and topsoil, thicknesses between 0.5 and 3.5 m. Underneath the laterite, there is the sandy clay alterites of thicknesses between 5 and 40 m, in which one can identify horizons of allotérites and isaltérites. The water potential is important in the fractured base because all arrivals of water is only found in this part of the geological formations.
