Hydrocarbon saturation.

Field scale definitions define residual NAPL saturation in terms of NAPL mobility relative to the scale of the problem (e.g. oil reservoir production, NAPL plume recovery). One definition for residual oil saturation is focused on liquid saturated cond itions in the reservoir or aquifer when oil (or LNAPL) ceases to be recovered.

The hydrocarbon–water transition zone is constrained upwards by the hydrocarbon zone where the water saturation is close or equal to the irreducible water saturation (Fig. 1b). Capillary pressure is an important characteristic of rock that helps determine where hydrocarbons and water are located in the subsurface (Wu 2004 ).

A bromine water test is employed to assess if a hydrocarbon is saturated or unsaturated.
