Aerial leak detection by use of Differential Absorption LIDAR (DIAL) technology has become a viable technique for detecting, quantifying and pinpointing methane emissions from underground pipelines and operating facilities. This paper describes a number of leak detection survey projects performed throughout North America using the DIAL technology from a fixed wing aircraft. The technology was deployed: • In test situations designed to measure the detection capability and lower detection threshold; • In long distance, large diameter, high pressure natural gas transmission pipelines traversing extremely rugged terrain; • In medium pressure pipelines in populated, higher consequence areas. Results from each of the airborne DIAL leakage survey mission scenarios will be described.
