ABSTRACT:
In its broadest aspect, the present invention provides a method for inhibiting silica dissolution in the vicinity of a well penetrating a hydrocarbon-containing formation. It includes: (a) adding an amount of a chmeical compound to a wet steam which forms an alkaline component in the vapor phase of the wet steam effective to inhibit corrosion in the vicinity of the vapor phase condensate; (b) separating the wet steam into the liquid phase and the vapor phase; (c) removing an amount of the liquid phase from the wet steam effective to reduce silica dissolution in the vicinity of the liquid phase; and (d) injecting the wet steam into the formation.
