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 system fundamentals|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.
