Fibre-optic sensing has been used for a number of years in a variety of applications within the oil and gas industry. Technological developments such as distributed acoustic sensing are now evolving to meet the growing needs for efficiency and security.
REMOTE SENSING applications developed to monitor pipelines, wells and storage vessels have included Distributed Temperature Sensing (DTS) and strain sensors. DTS has been used in downhole applications to monitor well production as well as downstream to show vessel skin temperature and as a leak detection tool within LNG terminals. Strain sensors have been utilised in risers, flexible pipes and jackets to signal fatigue. Such methods have their limitations, yet recent developments in sensing techniques and algorithms are pushing out the boundaries of fibre-optic sensing applications.
