Abstract
A method for calibrating distributed temperature sensing (DTS) systems is disclosed. The method includes: receiving temperature data associated with one or more locations along a length of an optical fiber; calculating a set of unique calibration coefficients specific to each of the one or more locations along the fiber length; and applying the set of calibration coefficients specific to each of the one or more locations along the fiber length to the temperature data for calibrated correction thereof. Also disclosed is a system for calibrating DTS data and a wellbore for providing calibrated DTS data.
