1. A system for controlling flow in a well, the system comprising:
a well string having a plurality of flow control valves shiftable between an opened position and a closed position;
a common close hydraulic line connected to the plurality of flow control valves;
a plurality of open hydraulic lines, a corresponding open hydraulic line of the plurality of open hydraulic lines being coupled with a corresponding flow control valve of the plurality of flow control valves, wherein actuation of the corresponding open hydraulic line shifts the corresponding flow control valve to the opened position individually; and
a plurality of selective close circuits, a corresponding selective close circuit being connected between the common close hydraulic line and the corresponding open hydraulic line of the corresponding flow control valve to enable closing of each of the plurality of flow control valves independently of each other.
