A conceptual model of heavy hydrocarbon fate and transport in the environment. A conceptual model of heavy hydrocarbon fate and transport in the environment. Heavy hydrocarbons are typically released together with lighter hydrocarbon fractions that are found in most crude oils. This modifies the physical and chemical properties that significantly affect the transport on soils and in the subsurface. Releases of viscous refined bitumen or extremely heavy crude oils (APIo < 12) are unlikely to travel any significant distance in the soil or subsurface. David M. Brown et al.
