Patent ID: 8763692

Claim:
A device for heating a hydrocarbon formation comprising: an electrically conductive pipe having one or more radiating segments and one or more insulator segments interposed between said radiating segments; an electrical cable positioned adjacent to the electrically conductive pipe having a first conductor, a second conductor spaced apart from and electrically insulated from the first conductor, and a shield surrounding the first conductor and the second conductor, the shield having at least one discontinuity exposing the first conductor and the second conductor creating a connection site adjacent to an insulator segment; a radio frequency source connected to the first conductor and the second conductor and configured to apply a signal to the electrical cable; a nonconductive sleeve positioned around the electrically conductive pipe and the electrical cable prior to at least one insulator segment relative to the radio frequency source; and wherein at the connection site the first conductor is electrically connected to the conductive pipe just beyond an insulator segment and the second conductor is electrically connected to the shield.
