Abstract
A bypass device for bypassing a hydraulic piston in a wellbore with an outer tubular body. The outer tubular body can have a fluid control manifold. The fluid control manifold can have two control paths, two high pressure fluid paths, and two valves connecting with two high pressure fluid connecting paths. An inner tubular body can be disposed within the outer tubular body, and a piston chamber can be disposed between the inner tubular body and the outer tubular body. The piston chamber can include two piston chamber sections separated by a hydraulic piston.
