  • Wireless passive pressure sensor for downhole annulus monitoring
    Patent number: 9828848
    Abstract: A downhole pressure sensor to measure absolute pressure in an annulus and a method of measuring absolute pressure in an annulus are described. The sensor includes an inductor including primary windings and secondary windings, and a capacitor coupled to the secondary windings and disposed in the annulus, at least one of the plates of the capacitor being flexible. The sensor also includes a controller coupled to the primary windings, the controller introducing an input signal to the primary windings and receive a return signal from the primary windings, the return signal resulting from the input signal being transferred through the secondary windings to the capacitor and back through the secondary windings to the primary windings. The controller determines the absolute pressure from the return signal.

  • Communications protocol for downhole data collection
    Patent number: 9644475
    Abstract: A method of managing data obtained in a borehole is provided. The method includes monitoring a characteristic with at least one sensor and obtaining raw data therefrom; indexing the raw data with the at least one sensor; recording the indexed data with the at least one sensor; forming a data packet with the at least one sensor, the data packet including at least a portion of the indexed data and index information; and transmitting the data packet in a predetermined segment of a communication protocol.
