Abstract: A first RFID tag arrangement for actuating a downhole tool includes a non-metallic housing enclosing a passive RFID tag, power source, pulsed oscillator circuit, and energizer coil. The pulsed oscillator circuit drives the energizer coil to stimulate and activate the tag such that it can be read by an external reader. A second RFID tag arrangement includes a non-metallic housing enclosing a power source, a transmission circuit, and a transmitter coil. The transmission circuit can drive the transmitter coil to transmit a payload stored in the transmission circuit such that the payload is delivered to an external reader. A method of actuating a downhole tool includes placing the tool's RFID tag reader in listen only mode, introducing into the wellbore an active RFID tag that transmits its payload to the reader, and optionally configuring the reader to reprogram the tag when it receives the payload therefrom.

Abstract: A system or apparatus for use in downhole communication or detection comprises a downhole arrangement defining a throughbore and primary and secondary elements. One of the primary and secondary elements is provided on the downhole arrangement and the other of the primary and secondary elements is provided in the throughbore. The primary and secondary elements are configurable for coupling of an electromagnetic field therebetween. The primary or secondary element which is provided in the throughbore may be provided on a tool such as a shifting tool which is deployable through the throughbore. The secondary element may be configured to provide the electromagnetic field coupled between the first and second elements with one or more characteristic features. The system may be configured for use, in particular though not exclusively, for communicating information to and/or from a downhole tool in an oil or gas well.
