Latest Patents

James Allison holds a patent for a "Pressure-balanced rod piston control system for a subsurface safety valve." This control system features a control line that connects the surface to the top side of an actuating piston. The actuating piston is responsible for moving a flow tube downwardly to open the subsurface safety valve (SSV). A balance line runs from the surface to the bottom side of the actuating piston, ensuring pressure balance. The system is designed to overcome a return spring to open the valve when pressure builds in the control line. Conversely, the removal of pressure allows the return spring to close the valve. The design includes seals and leak paths that ensure a fail-closed situation in the SSV under various failure modes.
