ABSTRACT:
A correlation system is provided to allow association of readings from a cable that is supported by a string but that is coiled around or has slack in one or many locations to a specific location along the string itself. Heat sources can be placed along the string to periodically or continuously give off heat that can be detected by a cable such as a fiber optic. The location of the sources along the string is known and the location along the cable is determined from the location on the cable where the heat generated by the source is sensed. One or more sources can be used and correlation can be by periodic sampling or in real time. The sources may by powered locally or from the surface.
