Abstract:
A fiber optic cable assembly includes an elongate housing, a signal fiber placed inside the housing and extending longitudinally, and a plurality of sensing fibers placed inside the housing and extending longitudinally. The plurality of sensing fibers is placed around the signal fiber. Each of the plurality of sensing fibers carries a respective laser signal of a distinct frequency. The signal fiber carries one or more evanescent coupling signals responsive to the laser signals in the plurality of sensing fibers.

Claim (Index 19):
A method, comprising:\n transmitting laser signals to a plurality of sensing fibers in a fiber optic cable assembly, wherein each sensing fiber carries one laser signal, each laser signal has a distinct frequency, and the fiber optic cable assembly comprises:\n an elongate housing; and \n a signal fiber and the plurality of sensing fibers placed inside the housing and extending longitudinally, wherein the plurality of sensing fibers are placed around the signal fiber, the signal fiber carries one or more evanescent coupling signals responsive to the laser signals in the plurality of sensing fibers, and the fiber optic cable assembly is strapped outside a tubing in a wellbore formed in a formation; \n receiving, from the signal fiber of the fiber optic cable assembly, the one or more evanescent coupling signals; and \n based on the one or more evanescent coupling signals, determining characteristics of a down-going seismic signal and an up-going seismic signal.
