  • Distributed acoustic sensor with trackable plug
    Patent number: 11572759
    Abstract: A downhole well system can use a fiber optic cable that can be positioned downhole along a length of a wellbore. The well system may include a top plug, a bottom plug, or both that are used to contain a cement slurry during a cementing operation. The movement of the top plug and bottom plug may cause acoustic noise along the downhole portion of the casing. A reflectometer may detect the acoustic noise from strain in the fiber optic cable and determine a location of the top plug or bottom plug downhole.
