Abstract
A method for detecting leaks in pipelines, particularly those transporting natural gas is disclosed. Leak sensitive particles are added either as soluble particles or in a nitrogen atmosphere which will transmit signals to an appropriate sensor when a leak condition is detected. The sensors can be located along the length of the pipeline or in a pig that will be transported through the pipeline along with the leak sensitive particles.
