Abstract: A monitoring and mapping system of the space-time distribution of formation fluids in a reservoir (30) comprising: at least four transceiver devices (40) arranged to be applied at a predefined mutual distance along a casing pipe (12), each of the transceiver devices (40) comprising: a tubular body (41) arranged to be fit on the casing pipe (12), the tubular body (41) having at a first end a first longitudinal portion (42), at a second end a second longitudinal portion (43) and a third longitudinal portion (44) interposed between the first (42) and second (43) longitudinal portions; a coil (45) wound on the first longitudinal portion; a layer of elastomeric material (46) which winds the third longitudinal portion (43); an electrode (47) wound on the layer of elastomeric material (46); a peripheral N electronic control unit (48) associated with the tubular body (41); the monitoring and mapping system comprising a central electronic control and data acquisition unit (60) configured to drive the peripheral electronic control units (60) so as to selectively power the electrodes (47) and the coils (45).
