Synrift stratigraphy of the Cenozoic grabens in the West Natuna Basin (WNB) is commonly poorly constrained because few deep wells exist. Stratal slices were produced from high-quality Gabus and Belanak three-dimensional (3-D) seismic surveys to image synrift depositional architectures. Using 3-D seismic geomorphology, we identified five facies that were used to construct a detailed seismic stratigraphic interpretation. The interpreted synrift stratigraphy of the WNB shows a strong tectonic control. From this type of analysis, potential hydro-carbon system elements can be identified and mapped. Thus, in petroleum exploration situations in which few well data exist, 3-D seismic geomorphology can be used to provide key stratigraphic insights.
