1. A method, comprising:

  • introducing optical pulses into a fiber optic cable disposed along a length of a conduit;

    receiving acoustic signals that cause disturbances in the optical pulses propagating through the fiber optic cable; and

    performing distributed acoustic sensing (DAS) along the length of the conduit by sensing the disturbances, such that the sensing produces the functional equivalent of a plurality of sensors along the length of the conduit.
