  • METHOD AND APPARATUS FOR CONTINUOUSLY CHECKING CASING CEMENT QUALITY
    Publication number: 20230115721
    Abstract: A system for monitoring downhole cement quality in a cased well includes an active acoustic source that generates acoustic waves, a distributed acoustic sensor, and a controller. The distributed acoustic sensor includes an optical fiber disposed on an outer surface of a casing of the cased well; a pulsed laser coupled to the optical fiber and that transmits pulses of laser light along the optical fiber; a sensor that detects light that is backscattered and reflected by the optical fiber; and a processor that controls the pulsed laser, receives signals from the sensor, and converts the signals into acoustic information. The controller receives the acoustic information from the processor and identifies well integrity loss.
