DTS (Distributed Temperature Survey)

DTS is Distributed Temperature Survey (or Sensor).

DTS means distributed temperature sensing, using fiber optic cable. This method is based on monitoring light reflection in a fiber optic cable, being able to detect small temperature changes typically every meter. This is done without having any sensors implemented or connected to the cable - The entire cable is the sensing element. Selecting the correct DTS surface system is crucial in obtaining value of logging system, and many E&P companies have been disappointed in DTS since it has not provided the data value they hoped for or that the supplier sold to them. Reason for this is that surface systems are different from supplier to supplier, and you need to select a system that gives you the resolution and accuracy you need for your application. Doing steam injection efficiency monitoring may require a different system than you need for flow allocation in horizontal wells.
