Distributed Temperature Sensing

Optical fiber technology in a well allows operators to accurately and frequently monitor the temperature of the fluids in the wellbore. The fiber optic cable provides high resolution data at 0.5m intervals along the entire length of the well that be used to detect fluid flows in or near to the wellbore.

Permanently installed for well monitoring or temporarily deploy for well surveillance, DTS provides valuable data for leak detection, production optimisation and flow allocation.

As pioneers in the technology, we installed our first DTS system over 20 years ago. Our complete service enables the well operator to obtain the result they need, no matter where they are. Using best-in-class fiber optic cables, accessories and surface acquisition units, we have installed systems across a wide range of oilfield applications in the most challenging environments.
