Abstract
Method of exploiting and/or of monitoring the exploitation of a fluid such as a hydrocarbon fluid present in at least one geologic layer of an underground formation. From consecutive pressure and spontaneous potential measurements taken at least at one measurement point in at least one well drilled through at least the geologic layer of interest, the slope of a curve showing the evolution of the spontaneous potential gradient as a function of the pressure gradient is determined. Then, from this slope and from a graph representative of the evolution of the electrokinetic coupling coefficient as a function of the salinity for the layer considered, a salinity value is determined at the measurement point.
