A previous PRCI project (PR-015-084510, 2009) identified distributed temperature sensing (DTS) and acoustic emissions as potentially viable technologies for the detection of small leaks in liquid pipelines.

A previous PRCI project (PR-015-084510, 2009) identified distributed temperature sensing (DTS) and acoustic emissions as potentially viable technologies for the detection of small leaks in liquid pipelines. Much of the assessment that led to this conclusion was based upon manufacturer-generated literature. However, there is a lack of existing, publicly-available test data on these technologies as they relate to detecting small leaks in liquid pipelines. Such data are needed by pipeline operators in order to determine the value in supplementing their existing leak detection systems with one of these technologies. The long-term goal of the PRCI team providing oversight to this work is to conduct full-scale field testing of these technologies. However, it is first important to determine the parameters that affect performance in order to design the large-scale testing and to identify conditions for which the technologies are not suitable. A project encompassing analysis and laboratory testing of DTS systems and modeling of acoustic emissions systems was conducted.
Includes some analysis of different liquids including crude oil, propane, gasoline, and carbon dioxide.
