dc.description.abstractThe increasing number of recently acquired 3D seismic surveys over large areas of passive margin settings has led to considerable advances in the comprehension of deep-water depositional systems (Fonnesu, 2003).In this project have been used a 3D seismic data from Western part of the Lower Congo Basin, offshore Angola, to investigate deep-water depositional systems to characterize channel systems along the pinch out features in terms of geometries, morphometric and architectural elements with respect to the growing salt anticline. It is mainly based on attribute plan-view maps and 2D seismic sections view. For that, the studied stratigraphic sequence bounded by horizons A and B base and top respectively is subdivided in three different stages namely stage 1, stage 2 and stage 3 from extracted isoproportional slices. The interpreted stage 1 shows weakly confined system characterized by organized sinuous stacking channels A and B, 500 m 2km wide, 14 km long, east west trend for channel A and 150 m 1.5 km wide, 13 km long, east west trend for channel B. The channels in this stage are classified as meandering channel belts due to their sinuosity values according to Janocko et al., (2013). The interpreted stage 2 shows confined system characterized by disorganized stacking channels C and D, 1 2 km wide, 8 km long, northeast southwest trend for channel C and 1 3.5 km wide, 12 km long, east west trend for channel D. According to Janocko et al., (2013), the channels in this stage are considered non meandering channel belts due to their low sinuosity values. In the last stage 3, are interpreted different features such as polygonal faults, slump deposits and pockmarks.All different features identified in three studied stages, gives idea that the study area has been strongly affected by salt tectonics which therefore impacted the development, morphology and orientation of the channel systems within the studied stratigraphic sequence.Keywords: 3D Seismic data; Lower Congo Basin; Deep-water; Channel systems; Salt tectonics.nb_NO
