==Migration by diffusion==
==Migration by diffusion==
Migration by diffusion of light hydrocarbons in a water-filled pore system is extremely slow. Diffusion conveys hydrocarbons from areas of high concentrations to areas of lower concentrations. It is dominantly a dispersive force and is generally responsible for the loss of hydrocarbons, not their accumulation.
