Patent ID: 7886591

Claim:
A method for improving the determination of at least one multiphase flow parameter of a formation traversed by a borehole, comprising: suspending a resistivity logging tool in the borehole; propagating with the resistivity logging tool at a first salinity front in the formation; detecting with the resistivity logging tool a first response, said first response being induced by the first salinity front and a saturation profile of the formation; determining from the first response a first value for the at least one multiphase flow parameter of the formation; propagating with the resistivity tool a second salinity front in the formation; detecting with the resistivity logging tool a second response, said second response being induced by the second and the first salinity fronts and the saturation profile; determining an improved value of the at least one multiphase flow parameter of the formation from the first response, the second response and the first value of the at least one multiphase flow parameter.
