public enum ReservoirFluidType
extends Enum<ReservoirFluidType>

Enumeration of reservoir fluid types based on Whitson classification.

Classification is based on phase behavior characteristics as described in the Whitson wiki (https://wiki.whitson.com/phase_behavior/classification/reservoir_fluid_type/).
