ABSTRACT:
Apparatus and method for monitoring a fluid reservoir traversed by at least one well comprising the placing of at least one electrode communicating to the surface and fixed in permanent manner in the well. Hydraulically isolating the section of the well in which it is located from the rest of the well and providing electrical coupling between the electrode and the reservoir. Subsequently, a current is passed through the reservoir; and an electrical parameter is measured, whereby a characteristic representative of the reservoir can be deduced.
