Abstract
A method and apparatus for treating steam which is to be injected into a formation through a gravel pack well completion by preventing dissolution and removal of silica from the gravel pack. The steam is flowed through a treatment vessel which is filled with a silica-containing material, e.g. sand, where it dissolves silica from the sand prior to injection through the gravel pack. Since the treated steam is already substantially saturated with silica, it will not dissolve any substantial amounts of silica from the gravel pack. The treatment vessel can also be heated during treatment, if desired.
