Distributed Acoustic Sensing For Pipeline Monitoring

Optical fiber is increasingly being deployed in many upstream and midstream applications. It is now regularly used to provide high bandwidth telecommunications and infrastructure for SCADA, and is being used more to sense pressure, temperature and strain, along buried onshore pipelines, on subsea pipelines and down hole. In this article results are presented from the latest sensing capability using standard optical fiber to detect acoustic signals along the entire length of a fiber.
