Abstract
A remote hydraulic system for controlling a valve of a wellhead or frac manifold includes a remote hydraulic skid, control skid, and power supply skid. The remote hydraulic skid includes a hydraulic reservoir, a hydraulic pump, an accumulator, a hydraulic manifold operatively coupled to the accumulator, and a hydraulic valve operatively coupled to the hydraulic manifold. The hydraulic valve is operatively coupled to the valve of the wellhead or frac manifold by a hydraulic line. The control skid includes an interface and is operatively coupled to the remote hydraulic skid by a control line. The control skid is adapted to control the actuation of the hydraulic valve. The power supply skid is coupled to the remote hydraulic skid to provide the power necessary to drive the hydraulic pump on the remote hydraulic skid. The remote hydraulic skid is positioned within a hazardous zone around the wellhead, while the control skid and power supply skid are positioned outside of the hazardous zone.
