Fiber Optics for Distributed Temperature Sensing (FODTS)

This training course utilizes an operating model that relies on Raman scattering in optical fibers to convert temperature into an optical signal. The DTS technology has a wide range of well-monitoring applications, including flow metering, flow assurance, leak detection, gas-lift surveillance, and permanent temperature logging.

The Fiber Optics for Distributed Temperature Sensing (DTS) course is designed for professionals who work with fiber optic systems used for temperature monitoring and control in various industries such as oil and gas, power, mining, and infrastructure.
