  • Localized wireless communications in a downhole environment
    Patent number: 10053976
    Abstract: A system for use in a wellbore can include a first transceiver that is operable to transmit a wireless signal. The first transceiver can be positioned in an electrically isolated chamber between a tubular and a casing string for confining a transmission of the wireless signal to within the electrically isolated chamber. The system can also include a second transceiver that is positionable in the electrically isolated chamber for receiving the wireless signal from the first transceiver.
    Type: Grant

  • DOWNHOLE FLUID FLOW DIRECTION SENSOR
    Publication number: 20180010444
    Abstract: A system for use in a wellbore can include a component that is positioned in a flow path through a tubular for fluid. The component can be movable by the fluid between a first position and a second position for changing a magnitude of a magnetic field that is detectable by a sensor or inducing a current in the sensor. The system can also include the sensor positioned external to the tubular for determining a direction of a flow of the fluid through the tubular based on the magnitude of the magnetic field or a polarity of the current.
