System and Method to Obtain Vertical Seismic Profiles in Boreholes Using Distributed Acoustic Sensing on Optical Fiber Deployed Using Coiled Tubing

摘要

A system and a method for performing a borehole operation, wherein the system may comprise a coiled tubing string and a fiber optic cable disposed in the coiled tubing string and wherein the fiber optic cable is strain-coupled to the coiled tubing string. A method of performing a borehole operation may comprise disposing a coiled tubing string into a borehole and wherein a fiber optic cable is strain-coupled to the coiled tubing string, and measuring at least one property of the borehole with the fiber optic cable.
