  • Patent number: 10690871
    Abstract: A fiber optic cable assembly includes an elongate housing, a plurality of fiber optic cables placed inside the housing and extending longitudinally, and acoustic isolating material placed inside the housing and extending longitudinally. The acoustic isolating material includes a plurality of outwardly radially extending arms extending from a center of the housing towards a circumference of the housing. The plurality of arms divides a space inside the housing into a plurality of acoustically isolated sections. Each acoustically isolated section extends longitudinally. Each acoustically isolated section includes at least one of the plurality of fiber optic cables. Each acoustically isolated section is acoustically insulated from remaining sections of the plurality of acoustically isolated sections. A surface of the acoustic isolating material of each acoustically isolated section is covered by acoustic reflective material.

  • Publication number: 20200191645
    Abstract: A variable-frequency light source is configured to emit a light beam and modulate a frequency of the light beam. A fiber optic cable is attached to the variable frequency light source. The fiber optic cable is configured to receive the light beam at an inlet and pass the light beam to an exit. Multiple optical detectors are attached to the fiber optic cable. Each of the optical detectors is configured to detect a specified frequency of light that is backscattered through the fiber optic cable. An actuation mechanism is attached to the fiber optic cable. The actuation mechanism is configured to deform the fiber optic cable in response to a stimulus.

  • Publication number: 20200149395
    Abstract: A flow meter includes a cylindrical tubing configured to be positioned in a wellbore, the cylindrical tubing including a flow mixer configured to produce a turbulent fluid flow of a multiphase fluid in the wellbore. The flow meter includes a tuning fork disposed in the cylindrical tubing separate from the flow mixer, the tuning fork configured to contact the turbulent fluid flow of the multiphase fluid and vibrate at a vibration frequency in response to contact with the turbulent fluid flow, and a controller to determine a fluid density measurement of the multiphase fluid based at least in part on the vibration frequency of the tuning fork.
