DTS Systems Have Been Used in Oil & Gas Production

Date: 2015-08-22

“Conventional temperature measurement systems are inconvenient to use in harsh operating environments. They are susceptible to electromagnetic interference, extremely high temperatures, and corrosion in humid conditions. In the oil &gas industry, temperature measurement is an important requirement for applications such as downhole reservoir monitoring and well completion. Some applications require temperature sensing systems that can operate at high temperatures and are immune to any electromagnetic interference. Distributed temperature sensing systems provide the perfect solution for such applications. 

For over a decade, DTS systemshave been used in oil &gas production. They provide a cost-effective solution for obtaining highly accurate temperature measurements. In DTS systems, a single optical fiber acts as a sensor, replacing the need of multiple point sensors. DTS systems have a high spatial resolution and long range, making them extremely useful in conditions wherein it is difficult to trace the exact sensor location after preliminary engineering. As DTS systems rely on optical sensing, they are free from any electromagnetic interference as well as the risk of electric hazards which affect electrical sensing systems. The systems are increasingly used in other applications such as power cable monitoring, fire detection, and pipeline leakage detection.

The improved reliability of DTS systems, their ability to operate in harsh environments, and their application in improving brownfield operations are some of the key drivers of the DTS technology. However, technical difficulties in sensor cable deployment remains one of the biggest restraints of this technology. The subsea market presents a high potential for the growth of the DTS technology in the near future. The most important challenge ahead for DTS system providers is the high cost of DTS systems. The key to success, however, is providing the best value solution to customers that justifiesthe relatively higher price of these systems.

Some of the companies involved in the market include AP Sensing GmbH (Germany), GESO(Germany), Halliburton Co. (U.S.), LIOS Technology GmbH (Germany), Omnisens SA (Switzerland), Schlumberger NV (U.S.), Sensornet Ltd. (U.K.), Sumitomo Electric Industries Ltd. (Japan), Tendeka B.V. (Netherlands), Weatherford International Plc. (Ireland), and Yokogawa Electric Corp. (Japan).
