Method for characterizing the integrity of a reservoir by reflectometry

Abstract

Method for characterizing the integrity of a tank (200) comprising at least one electrical conductor (202) arranged in or on the tank wall in a coiled arrangement, the method comprising the steps of, for each electrical conductor: Injecting (701) a signal at a first end of the electrical conductor, Measuring (702) the signal after its propagation in the electrical conductor, Analyzing (703) the signal measurement to identify at least one amplitude peak characteristic of a reflection of the signal on a defect in the electrical conductor located in an area of ​​the tank surface, Deducing (704) a location of the area of ​​the tank surface impacted by a tank integrity defect from the time of flight of at least one amplitude peak.
