| dc.description.abstract | 3D seismic data from the offshore Congo Basin, Angola has been performed in order to do geological interpretation of deep-marine deposits and understand the depositional system in the basin. Architectural elements, such as submarine channels, were mapped to see the geomorphologic characteristic.
The interpretation was done by dividing the seismic section into three stratigraphic units that are bounded by horizons interpreted. In order to help the interpretation, surface maps, isopach and attribute maps were extracted and the time slices was also displayed to show the channels migration. Analyses of the channelized depositional environments reveal two distinct depositional styles and results morphologies. Channels interpreted within Unit I and II are defined laterally migrating. The channels of Unit III exhibit a pronounced vertical aggradational motif.
