6. A method for operating wellbore equipment with a control system, the method comprises:
providing a control system comprising:
a hydraulic pump,
a valve bank,
a hydraulic fluid reservoir; wherein the hydraulic pump is fluidically connected with the valve bank; wherein the valve bank is fluidically connected with the hydraulic fluid reservoir; wherein the hydraulic fluid reservoir is fluidically connected with the hydraulic pump,
an accumulator fluidically connected to the hydraulic pump and the valve bank and the accumulator is configured to store pressurized hydraulic fluid from the hydraulic pump;
wherein a first output line connects the hydraulic pump to the accumulator; wherein a second output line connects the accumulator to the valve bank; wherein an exhaust line connects the valve bank to the hydraulic fluid reservoir; and wherein a hydraulic fluid input line connects the hydraulic fluid reservoir to the hydraulic pump; and
wherein the hydraulic fluid reservoir and the hydraulic pump are disposed in a first wellbore zone between a tubing hanger and a safety valve; wherein the accumulator and the valve bank are disposed in a second wellbore zone between a production packer and an interval control valve; wherein the first output line traverses at least a third wellbore zone to connect the hydraulic pump to the accumulator; wherein the exhaust line traverses at least the third wellbore zone to connect the hydraulic fluid reservoir to the valve bank;
flowing pressurized hydraulic fluid exiting from the hydraulic pump to the valve bank; and
distributing the pressurized hydraulic fluid from the valve bank to the wellbore equipment.
