  • Mitigation of attenuation for fiber optic sensing during cementing
    Patent number: 11149520
    Abstract: A cementing tool with a top seal and a bottom seal may be positionable within a casing string of a wellbore. A fiber optic line may be coupled to the top seal and to a second fiber optic line coupled to a bottom seal that is deployed within an annulus. An amplifier coupled to the cementing tool may amplify a source optical signal from a light source and a sensing measurement signal from the second fiber optic line and the first fiber optic line. One or more operational parameters, such as cementing parameters, may be adjusted based, at least in part, on the sensing measurement signal.

  • Cement plug tracking with fiber optics
    Patent number: 10400544
    Abstract: A system can include a cementing tool positionable within a casing string of a wellbore. A receiver that is positionable at the surface of the wellbore can receive an optical signal. A locator coupled to the cementing tool can generate an electrical signal in response to detecting a change in a surrounding magnetic field. A light source can generate an optical signal. A fiber optic cable can transmit the optical signal generated by the light source. A fiber reel can dispense the fiber optic cable from an end of the fiber optic cable.

  • DISTRIBUTED OPTICAL SENSING USING COMPRESSIVE SAMPLING
    Publication number: 20180058197
    Abstract: Distributed optical sensing systems utilize compressive sensing techniques to determine parameters sensed by a waveguide. The system generates light that is sent along a sensing waveguide, thereby producing backscattered light. A compressive sampling filter forms part of the system, and is used to selectively block portions of the generated light or the backscattered light. The backscattered light is received by a receiver and used to determine one or more parameters.
