Abstract
This invention relates to a method of producing supercritical carbon dioxide from a well along with minor amounts of water having formation salts dissolved therein. Precipitation of salts carried by the formation water in the pump is prevented by continuously injecting water into the vicinity of the pump intake so as to dilute the formation water before it, or at least a portion of it, is vaporized into the water phase of the supercritical carbon dioxide. The volume of injected, substantially fresh water must be sufficient to handle the vaporization of water into the carbon dioxide in the pump as well as dilute the formation water so that the salts carried thereby remain in solution.
