A system monitors and controls the injection of additives into formation fluids recovered through a subsea well. The system includes a chemical injection unit and a controller positioned at a remote subsea location. The injection unit uses a pump to supply one or more selected additives from a subsea and/or remote supply unit. The controller operates the pump to control the additive flow rate based on signals provided by sensors measuring a parameter of interest. A one mode system includes a surface facility for supporting the subsea chemical injection and monitoring activities. In one embodiment, the surface facility is an offshore rig that provides power and has a chemical supply that provides additives to one or more injection units. In another embodiment, the surface facility includes a relatively stationary buoy and a mobile service vessel. When needed, the service vessel transfers additives to the chemical injection units via the buoy.

Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing. The void spaces between the insulator and the tubing inside wall can be filled with a sealing material. Alternatively, the voids around the substantially centralized conductors can be used as flow channels for the transmission of fluid pressure to a remote location, such as downhole. The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.
