Principle of Downhole Temperature Measurement Optical Cable in Samoa

Distributed temperature sensing systems (DTS) are devices which measure temperatures by means of functioning as linear. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances. Typically the DTS systems can locate the temperature to a spatial resolution of 1 m with accuracy to within ±1 °C at a resolution of 0.01 °C. Measurement distan.
