As the quality of seismic data has improved over the last decade, more and more geological signatures have been revealed from high resolution 3-D seismic volume. Now, 3-D seismic data allows the geologist to not only slice the earth in profile but also in plan view, “which gives us an image of paleogeography - a direct visualization of the paleogeography (Possamentier, 2000), which is now commonly recognize as seismic geomorphology.Recently tangential application of geomorphic principles to the study of stratigraphic sequences, reservoir heterogeneity and geobody formation has begun to recognize the additional insight that can be developed when we apply knowledge gained through modern geomorphic study to interpreting older strata and processes (Carter, 2003, Posamentier and Kolla, 2003, Posamentier, 2003). Evolving image technologies now enable geoscientists to see in greater detail than ever before how seascapes and landscapes have evolved through time. Two 3D mega-merge seismic dataset (Belanak and Gabus) in the West Natuna Basin of Indonesia (Figure 1), covering about 3,154 square kilometres (Figure 2), are used for this study. The seismic volume had been sliced using a stratal slice methode in the Neogene interval down to approximately two seconds two way time (TWT). The results are showing a spectacular fluvial and fluvial-deltaic features of Upper-Mid Miocene.
