Abstract:
1. A method of locating pressure communication through a breach in an interior pipe of a nested multi-pipe production well wherein the vertical position of the breach is radially encompassed by the next outermost pipe, said method comprising the steps of: first, connecting at least two well pipes of a nested multi-pipe production well to a collection reservoir to allow fluid communication thereto; second, sealing said at least two well pipes to maintain pressure therein; third, measuring a pressure parameter within each of said at least two well pipes until said pressure parameter indicates a stabilization of pressure therein; fourth, altering the pressure within one of said at least two well pipes; fifth, measuring an internal pressure parameter within each of the remainder of said at least two well pipes; and sixth, stabilizing the pressure within said one of said at least two well pipes.
