F-29 ISOLATING INDIVIDUAL CHANNEL SEQUENCES USING 3D VISUALIZATION AND MULTI-ATTRIBUTE TECHNIQUES IN A STACKED CHANNEL COMPLEX ULTRA DEEPWATER BRAZIL Summary 1 The complex stacking patterns and internal geometry of channels are very difficult to interpret in 2D or 2.5-D interpreting environments. Using geovolume visualization and interpretation (GVI) in a 3-D environment along with seismic attribute analysis is key to understanding the geological relationships of these channel complexes. This paper will give an example workflow to accurately and quickly evaluate these systems and isolate individual channel elements. Utilizing techniques such as multi-attribute voxel detection and surfaces that block auto picking allow
