    Abstract: A subsurface safety valve actuation system in well tubing comprising a safety valve, piston assembly, motor, pump, spring, reservoir, first valve, and second valve configured to provide pressure in a chamber of the piston assembly that drives the safety valve to an open position, retain pressure in the chamber that retains the safety valve in the open position, release pressure in the chamber via a first hydraulic release path and/or a second hydraulic release path between the chamber and the reservoir that extends through the first valve and second valve, respectively, and the first and second hydraulic release paths being independent from each other, whereby pressure in the chamber that retains the safety valve in the open position may be released via the first or second hydraulic release path when there is a fault in the other of the first or second release path.
