Fiber Optics for Distributed Temperature and/or Strain Sensing (FODTSS)

The DTSS training course is focused on the Brillouin scattering mechanism that utilizes the DTSS system. This system analyzes the target object's thermal and strain effects by combining the DTS and the DSS systems. The DTS measures temperature properties while the DSS provides measurements to determine the location and severity of deformation in well casing. In addition, the DSS provides insightful data that estimates the stresses inherent at perforations during oil output stimulations.

The Fiber Optics for Distributed Temperature and/or Strain Sensing (DTSS) course is tailored for professionals engaged in the deployment, maintenance, and use of fiber optic systems for distributed sensing of temperature and strain. DTSS technology is widely applied in industries like oil and gas, civil engineering, energy, and infrastructure, where it enables real-time monitoring over long distances. The course provides a comprehensive understanding of how DTSS systems work, their applications, installation techniques, and best practices.
