RESUMO:

The sequence stratigraphy applied to rifte basins consists of an adaptation of the classic model that is in full consolidation phase. The guiding principles of sequence stratigraphy are applied in any sedimentation context. They are fundamental to understanding the depositional history of a basin. The present work had as objective to study the seismic stratigraphy framework of Tucano Sul basin under the bias of sequence stratigraphy applied to rifte basins in order to correlate this study with the Recôncavo basin. From the integration of the seismic sections associated to the data of 15 wells (geophysical and lithological profiles) the data were processed in the IHS Kindle seismic interpretation software. The seismic stratigraphic analysis involved the interpretation of reflector terminations, definition of the seismostratigraphic units from the mapping of key surfaces as well as the characterization of the major seismic facies. As a result, five seismostratigraphic units were identified according to the model adopted here: Pre-rift unit, Rifte 1, Rifte 2, Rifte 3 and Post-rift unit. Five seismic facies were defined, SF1 to SF5, each with its characteristic parameters. At the end, a discussion was proposed about the seismostratigraphic correlation with the Recôncavo basin. For the rifte interval, Tucano Sul presented a seismostratigraphic sequence less than the Recôncavo basin, indicating an important erosive event during its development.
