Passive Ultrasonic Imaging: a novel LDAR tool for gas leak detection and quantification

Florian Perrodin - Distran Ltd


Ultrasound as a leak detection method in Oil & Gas has been used with little success in the past due to its time consuming nature, and the heavy training requirements. Instead of using a single microphone, novel devices such as Distran Ultra Pro have a microphone array that produces acoustic pictures instead of playing sound like previous devices. Overlaid with an optical image in real-time, the user is able to instantly pinpoints the leaks in a radius of 30 feet. The technique allows additionally to quantify leakages rate in real-time. Advantages and limits of the technique will be presented.
