Abstract:
1. A process for refining a model of a reservoir containing fluids (W, O), the model having as an input an estimate of a relative permeability value (krO, krW) of at least one of the fluids in the reservoir as a function of the saturation of at least one of the fluids (W, O), the method comprising: (a) determining, for one of the fluids of the reservoir, a saturation distribution on the basis of a measurement (SDM) of a physical property in the reservoir; (b) creating a dynamic model for the flow of fluids in the reservoir; (c) generating a simulated saturation distribution (SSD) by the dynamic model; (d) comparing the SSD with the SDM; and (e) if it is determined from the comparing step d) that the SSD and SDM coincide the dynamic model is considered reliable and the relative permeability value is output, otherwise updating the dynamic model with an intermediate relative permeability value (krO
