Abstract: Two control systems are provided to run in parallel between a surface location and the final controlled element, in this case a subsurface safety valve. The primary control circuit is controlling until a predetermined signal is given to the secondary control line which has the effect of actuating the valve a single time against the force of a bias or a shear pin that breaks. The movement of a shuttle in the housing due to the predetermined signal being provided in the secondary line puts the secondary control system in the position of running the tool. The primary system is valved off and cannot return into service. There are just two lines into and out of the housing to make the valve operate at the desired location. A test port is provided for surface testing.

Abstract: An operating control line is in communication with an operating piston for the safety valve as well as an equalizing piston such that pressure in the operating control line opens the safety valve and holds the equalizer valve closed. A balance chamber receives fluid from an operating piston in the safety valve when the valve opens to displace a floating piston to the open position. Operating control line pressure reduction allows valve closure and opposite floating piston movement to the closed position. If the floating piston is forced by a tubing seal leak against the open position travel stop, pressure in a balance control line against the equalizing valve member moves it from a seat to then equalize pressure on opposed ends of the floating piston allowing a bias force to move the floating piston off the open position stop so the safety valve can open despite the tubing leak.

Abstract: An equalizer valve is hydraulically operated by a pair of control lines running from a remote location such as a well surface. The use of control lines to make a mandrel or piston move in opposed directions removes the need for a spring or compressed gas to act as a spring against the anticipated hydrostatic force in a single control line system that is dependent on setting depth. The equalizer valve with its pair of control lines is insensitive to setting depth. Three seals on the mandrel are used to move the mandrel with the two control lines in opposed directions and to apply a net force to the mandrel. The seal applying the net closure force is exposed to a low or atmospheric chamber to make the second seal operate reliably using a large differential.
