Gas leaks and unsanctioned siphoning of gas can cause major incidents resulting in both economic losses and environmental damage. As knowing about the existence of a leak is not always enough to launch a corrective action, it is crucial to develop efficient method of locating the leak. The objective of this paper is to describe the numerical method of finding leakage position location, which is based on reduction of the original problem to the optimization problem and resolving it using mathematical modeling of nonstationary nonisothermal modes of gas flow in linear sections of the gas-transport system with gas leaks (or unsanctioned siphoning of gas). The method has high operation speed.
