Abstract
A method of utilizing fiber-optic cables either previously installed in adjacent wells or currently installed as part of the drilling or milling process to sense vibrations or acoustic signatures within an adjacent or the currently drilled wellbore. The vibrations or acoustic signatures may then be used to determine the location, including the depth, of a tool run into the well on coil tubing. In addition to determining the location of any tools run into the well on coil tubing, a determination of the operating condition of the tools may also be made based upon the vibrations or acoustic signatures of the tools received via the fiber-optic cables.
