Fiber optic sensing, and specifically Distributed Temperature Sensing (DTS), are powerful technologies extremely well
suited for monitoring of geothermal wells and geothermal energy production facilities. This paper will discuss fiber
optic technologies for high temperature sensing and monitoring applications in geothermal energy plants.
Distributed Fiber Optic Sensing is a powerful technology with wide spread use in applications from down-hole oil & gas
wells to environmental monitoring of streams. This paper will highlight some of the various technologies and
applications. Recent advances in multi wavelength Raman systems will also be discussed.
