    Abstract: A petroleum well for producing petroleum products that incorporates a system adapted to controllably route communications and/or electrical power having a time-varying current through a piping structure in the well, and methods of producing petroleum products use such a well, are provided by the present invention. The system comprises a first induction choke, a second induction choke, and a controllable switch. The first induction choke is located about a portion of a first branch of the piping structure. The second induction choke is located about a portion of a second branch of the piping structure. The controllable switch having two switch terminals. A first of the switch terminals I is electrically connected to the piping structure on a junction side of the induction chokes. The first and second branches of the piping structure intersect on the junction side of the induction chokes. A second of the switch terminals is electrically connected to the piping structure on another side of at least one of the induction chokes.
