Patents by Inventor Hugues Bouvier

Hugues Bouvier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9982528
    Abstract: Methods and related apparatus pertaining to downhole and surface telemetry, such as a method in which a telemetry system is provided with a communication path formed with an electrically conductive transport medium coupled across a plurality of downhole nodes. Such method includes operating on the communication path with a multi-drop system that provides telemetry to the downhole nodes in a wellbore, including employing modulation in a master-slave arrangement using binary differential phase shift keying or differential quadrature phase shift keying.
    Type: Grant
    Filed: July 30, 2015
    Date of Patent: May 29, 2018
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Adolfo Recio, Tamim Sawaf, Ryan Parasram, Hugues Bouvier, Robert Tennent, Scott Cook
  • Patent number: 9695686
    Abstract: Devices, systems and methods for transmitting downhole data are provided. The devices include a rotor-stator modulator configured for use in a drill string, and a drive and control system configured to drive the rotor according to a modulation scheme resulting in both oscillating and full rotational movement. The modulation scheme can comprise a trajectory algorithm such as a QAM trajectory algorithm. The systems include a modulator disposed within a drill string which creates modulated pulses according to an algorithm providing for both oscillating and full rotational movement of the rotor, and may also include a demodulator. The methods include transmitting coded data by driving a rotor relative a stator disposed in a drill string according to a modulation scheme that provides both oscillating and full rotational movement and results in modulated mud pulses representative of data recorded downhole, and may involve decoding the data.
