Hydrocarbon [[migration]] appears to occur in spatially limited areas (always unsampled because of their small size) and in discrete time intervals. It leaves either no trace or a trace that is continually modified or destroyed by later events. Effective hydrocarbon migration occurs along discrete pathways, not along broad, uniform fronts. These pathways are determined by the pore networks, the interaction of these networks between formations, and the stratigraphic variation within the basin. Within the carrier/reservoir bed, the migration pathway is controlled by the structural configuration of the contact with the overlying seal and the continuity of both the carrier [[permeability]] network and the overlying seal. This section discusses the general characteristics of these paths and shows several examples.
