Distributed fibre optic sensing (DFOS) has emerged 20 years ago with the ability to monitor temperature over 10s km at high spatial and temporal resolution. Since the technology is now able to monitor static and dynamic strain as well as strain rate. While most of the applications were first directed to pipeline monitoring, geotechnical work and condition monitoring, one of the biggest growth areas nowadays is subsurface characterization and monitoring for water, mining and energy applications. The technology is well suited for subsurface applications as it is robust, reliable and have low footprint. Over the years, the technology has been used as an active or passive seismic sensor, wellbore monitoring tool or surface ground motion detector.
In the talk, we briefly introduce the technology before presenting few examples of applications to the Resource sector. By combining DFOS systems to conventional sensors and enhanced data management, we illustrate the opportunities for improved knowledge and better-informed decisions.
