Abstract

A method and system for detecting and locating a breach of a pipe in nested multi-pipe petroleum wells using pressure valves and pressure sensors. The method comprises the steps of, connecting at least two of the well pipes of a nested multi-pipe production well to a collection reservoir to allow fluid communication from the well into the reservoir; sealing the well pipes to maintain the pressure therein; measuring a pressure parameter within each of said at least two well pipes until said pressure parameter indicates a stabilization of pressure therein; altering the pressure within one of the well pipes; measuring a pressure parameter within the other well pipes; and stabilizing the pressure in the well pipe within which the pressure was previously altered.
