Simulation modeling accounting for reservoir fluid properties heterogeneity

Current article deals with fluid properties heterogeneity. The reasons of this phenomenon are analyzed. 3D digital modeling of formation, saturated with oil having variable properties (density and viscosity) is performed. It is compared with model, built in the frameworks of classic approach, where oil has constant density and viscosity. It is shown, that accounting for oil properties heterogeneity allows making oil field design and planning of different activities more precisely.
