The interpretation and recognition of Depositional Systems using seismic data require a strong knowledge in stratigraphy, structural geology, tectonics, biostratigraphy, sedimentology and geophysics; even when a geoscientist doesn’t be a specialist of one of these. The mentioned disciplines interact and complement each other in different stages of study and exploration of hydrocarbon basins. Five stages have been proposed and studied in Interpreting Depositional Systems. (1) Review of basic concepts used in the definition of Depositional Sequences and Systems Tracts within the context of sequence stratigraphy. (2) The deepening in the physical foundations of rocks, that allows to obtain images of the subsurface through the application of seismic reflection method. It also is indicated how to tie the seismic data with well data through the synthetic seismogram. (3) The seismic stratigraphic interpretation, describes how Depositional Sequences and their Systems Tracts are interpreted in the well and seismic data. (4) The recognition of Depositional Systems, describes how the seismic facies analysis is more accurate on the interpretation, because of the association of particular Systems Tracts with particular deposition processes. The Depositional Sequences and Systems Tracts have predictable stratal patterns and lithofacies; thus, they provide a new way to establish a chronostratigraphic correlation framework based on physical criteria. (5) The advanced seismic interpretation allows geoscientists extract more information from seismic data and their applications include hydrocarbon play evaluation, prospect identification, risk analysis and reservoir characterization.
