  • Publication number: 20230033128
    Abstract: An optical system performs a method for measuring an acoustic signal in a wellbore. The optical system includes a light source, an optical fiber and a detector. The light source generates a light pulse. The optical fiber has a first end for receiving the light pulse from the light source and a plurality of enhancement scatterers spaced along a length of the optical fiber for reflecting the light pulse. A longitudinal density of the enhancement scatterers increases with a distance from the first end to increase a signal enhancement generated by the enhancement scatterers distal from the first end. The detector is at the first end of the optical fiber and measures a reflection of the light pulse at the enhancement scatterers to determine the acoustic signal.

  • Patent number: 11561318
    Abstract: Embodiments of the present invention use radar technology to detect features or conditions in a well. A radar unit having an electronics subsystem and an antenna subsystem is positioned downhole in the well. The radar unit is coupled receive power from and communicate with to a surface system. The electronics subsystem generates RF signals which are provided to the antenna subsystem, generating radar wavefronts that are propagated toward areas of interest (e.g., farther downhole). The radar wavefronts may be electronically or mechanically steered in the desired direction. The antenna subsystem receives radar signals that are reflected back to the unit by features or conditions in the well. The received reflected signals are converted to electronic signals that are interpreted by the electronics subsystem of the radar unit or by the surface system to identify the features or conditions that caused the reflections.

  • Patent number: 11563630
    Abstract: Disclosed herein is a system including a wellsite controller. The wellsite controller receives workflow inputs such as wellsite details and communications settings, generates a local configuration entry including the workflow inputs, sensor configuration information about wellsite sensors connected to the controller, and a unique identifier for the controller. The unique identifier is based upon the workflow inputs, the sensor configuration information, and location information for the wellsite. The controller generates a registration message from the local configuration entry. A server receives the registration message, and compares the unique identifier to a store of known identifiers. If the unique identifier does not match one of the known identifiers, the server recognizes the controller as being newly added, adds the wellsite to a monitoring system of the server by creating an entry for the wellsite from the registration message, and attempts to map the wellsite sensors to the entry for the wellsite.
