Abstract: The present invention relates to a system for facilitating the extraction of hydrocarbons. Tubular protection for an extraction system is provided using the RF heating of highly viscous hydrocarbons in situ by means of an antenna having a coaxial array of mode converters.

Abstract: A pipe for cableless bidirectional data transmission and continuous circulation of a stabilizing fluid in a well for the extraction of formation fluids includes a hollow tubular body which couples with respective drill or completion pipes; a radial valve associated with the tubular body, the radial valve connectable to a pumping system outside the tubular body; an axial valve associated with the tubular body; a communication module associated with the tubular body that includes at least one metal plate selected from a transmitting metal plate, a receiving metal plate, and a transceiver metal plate; an electronic processing and control unit that processes signals to be transmitted by means of the at least one metal plate or signals received by means of the at least one metal plate; and one or more supply batteries for feeding the metal plates and the electronic processing and control unit.

Abstract: System for cableless bidirectional data transmission in a well for the extraction of formation fluids comprising: a plurality of rods connected to each other in succession so as to form a rod string, which extends from the surface to the bottom of the well, the rod string being associable with a plurality of sensors configured for continuously detecting a plurality of parameters relating to the fluids circulating in the well and to the rock formation surrounding the well and/or to safety devices or other remote-controlled well instrumentation; a plurality of communication modules applied at predefined distances along the rod string and configured for the transmission of signals from and towards the bottom of the well; each of the communication modules including at least one metal plate.
