3D seismic volumes allow display of a structural image, identifying synclines and anticlines (horizontal - two-way time slice), and a stratigraphic image, identifying channel fed sand-prone fan reservoir facies (stratigraphic - RMS-amplitude extracation from an interval immediately above a sequence boundary.  Where the stratigraphic reservoir occurs within a structural trap is the drilling target, if further analysis suggests the occurrence of hydrocarbons.
