Abstract
An injection fluid is pressurized for injection into a subsea installation or equipment by using a flow of hydrocarbon production fluid to draw the injection fluid from a source and using pressure of the production fluid to pressurize the drawn injection fluid to an elevated pressure. In response to an ejector that is powered by the flow of the production fluid, a pressure booster draws in the injection fluid for pressurization. A portion of the production fluid is diverted to the pressure booster to pressurize and expel the injection fluid and is then exhausted to the ejector as more injection fluid is drawn in.
