Abstract (en)
[origin: WO0155554A1] A petroleum well having a wireless power and data communication system is provided. The well uses the tubing and/or casing to communicate with and power a plurality of devices, such as sensors and controllable valves. An electrically isolating portion of a tubing hanger at the surface of the well and a ferromagnetic choke downhole may electrically isolate the tubing from the casing and provide a communications path. A plurality of modems positioned downhole along the tubing string communicate sensor information to a modem and a computer located at the surface of the well. Based on an analysis of the sensor information received by the computer, instructions can be communicated along the tubing string to the controllable valves to adjust the flow rate of lift gas passing through the valves.
