This study applies the cluster and discriminant analyses in geophysical well log data from the Rovuma Basin -Mozambique. The main objective was to determine the lithological profile and fluid contacts in reservoirs. Five wells drilled on the same basin were evaluated. For the discrimination, a reference well was chosen for training, and the obtained functions from it were then applied to the remaining wells. The classification process comprehended three main phases. The two methods were applied in parallel and the results are compared in each classification phase. Reservoirs quality was also assessed by applying cutoffs in relation to shale content and effective porosity to delineate net reservoirs. Overall, both methods converged to the same lithological model and fluidtypes in reservoirs. Gas has been indicated as the most predominant hydrocarbon in the basin.
