An updated seismic geomorphological methodology has led to improved visualization of seismic-scale heterogeneities in the Chalk Group in the Danish Central Graben. The promise of the workflow is that it prepares a spatial framework for integration with other disciplines working at different scales. Such integration would lead to better predictions of reservoir quality away from the wells. The computation of a large amount of stratal slices that follows a 3D Relative Geological Time Model allows, consistent 'scanning' through the seismic stratigraphy. This revealed more subtle seismic geomorphological features than obtained with volumetric averaging. In addition, by using the latest spectral decomposition methods, projected upon these stratal slices, details that normally would be difficult to distinguish with classical attributes became apparent. Lastly, a new methodology that image processes seismic data, has revealed subtle linear features that are difficult to observe in normal seismic amplitude data. These can well present low-throw faults and fracture swarms as known from chalk outcrops with a similar burial history.
