Abstract: System for cableless bidirectional data transmission in a well (10) for the extraction of formation fluids comprising: a plurality of rods (11, 12) connected to each other in succession so as to form a rod string, which extends from the surface to the bottom of the well (10), the rod string being associable with a plurality of sensors (14) configured for continuously detecting a plurality of parameters relating to the fluids circulating in the well (10) and to the rock formation surrounding the well and/or to safety devices or other remote-controlled well instrumentation; a plurality of communication modules (20) applied at predefined distances along the rod string and configured for the transmission of signals from and towards the bottom of the well (10); each of the communication modules (20) comprising: at least one metal plate selected from: a transmitting metal plate (21); a receiving metal plate (22); a transceiver metal plate (35); an electronic processing and control unit (23) configured for processing signals to be transmitted by means of the at least one metal plate (21, 35) or signals received by means of the at least one metal plate (22, 35); one or more supply batteries (24) for feeding the metal plates (21, 22) and the electronic processing and control unit (23).
