This study shows a new way of applying rock physics depth trends. In seismic modeling we want to preserve internal geological variations in a system, even if depth and temperature change and diagenesis progresses. We suggest a workflow for creating realistic depth trends for whole geological systems, while honouring the internal variations within the system. A shale - sand interface can appear as soft, dim or hard, dependent on where in the diagenetic process the rocks are. This is also reflected in the rock physics approach described. The vertical variation observed in a geological system will be honored when applying it as an analogue on a new location, to create a realistic representation of the subsurface geology in the prospect area.
