Oil Characterization
Workshop
The petroleum characterization method in HYSYS converts laboratory analyses of condensates, crude oils, petroleum cuts, and coal-tar liquids into a series of discrete hypothetical components. These petroleum hypo components provide the basis for the property package to predict the remaining thermodynamic and transport properties necessary for fluid modeling.
HYSYS produces a complete set of physical and critical properties for the petroleum hypocomponents with a minimal amount of information. However, the more information you supply about the fluid, the more accurate these properties will be, and the better HYSYS will predict the fluid’s actual behaviour.
In this example, the Oil Characterization option in HYSYS is used to model a reservoir fluid. The fluid is a combined gas and oil stream.
