Abstract
A remote greasing system for lubricating a valve of a wellhead or frac manifold includes a grease supply skid, remote greasing skid, and a control skid. The grease supply skid includes a grease reservoir and a grease pump. The remote greasing skid includes a grease manifold and a grease supply valve. The grease manifold is operatively coupled to the grease pump of the grease supply skid by a grease trunk line. The grease supply valve is operatively coupled to the grease manifold. The grease supply valve includes an output port operatively coupled to a lubrication port of the valve of the wellhead or frac manifold by a grease supply line. The control skid is operatively coupled to the remote greasing skid by a control line. The grease supply skid and remote greasing skid are positioned within a hazardous zone, and the control skid is positioned outside of the hazardous zone.
