Abstract
A long distance power transfer coupler for wellbore applications system uses two or more wireless modules, each wireless module comprises a self-resonant coil, to transmit energy within a wellbore. The second, and potentially subsequent, wireless modules receive radiant electromagnetic energy from a nearby neighbor which the self-resonant coil converts to usable electromagnetic energy which may be used for power, data communications, or a combination thereof. A first module may be deployed at a predetermined position in the wellbore; a cable attached to a second length of tubing; and one or more second modules attached to the tubing and coupled inductively to a resistive load. The tubing and second module or modules are deployed downhole and electromagnetic energy transmitted wirelessly between the first module and the second module. Modules may be deployed in a completion string.
