Crude oils contain billions of components distributed in a surprisingly nonhomogeneous way.When performing very costly drillings, oil companies need to deduce the overall state of the reservoir from the geological data. Improving current prediction capabilities is the focus of the Diffusion and Soret Coefficients of Crude Oils MAP team. The approach is to determine all the transport properties of crude oils by describing their transport processes.These include the Soret effect, the tiny separation of components induced by the geothermal gradient (about 30K/km).Theoretical predictive developments will optimise the return of measurements from the experiment aboard the Foton-M2 satellite and the SoDiUM experiment.Validation by studies of g-sensitivity and the crucial role of asphaltenes are the most probable extensions of the studies.
