The movement of hydrocarbons through an entire stratigraphic section is generally ignored. Geochemists usually focus on migration out of [[source rock]]s, and [[Subsurface team|reservoir engineers]] usually study migration within carrier beds (reservoir-quality rocks). Little is known, though much is inferred, about cross-facies flow required when source rocks and reservoir-quality rocks are not adjacent to one another.
