We use seismic geomorphological interpretation derived from spectral decomposition attribute maps, extracted from a large (∼32500 km2) merged seismic data set from Central Luconia, Sarawak, to investigate shelf-to-slope depositional processes in a ramp margin setting. A full volume 3D seismic interpretation approach was applied using PaleoScan. Attribute maps derived from horizon slices through the relative geological time model provide information rich 3D images of the depositional systems and their spatial and temporal variation. This variability is important for the prediction of reservoir and seal distribution on the shelf and in the deepwater.
