摘要：

An aqueous solution having potassium silicate dissolved therein is injected into a subterranean sandstone formation containing water-sensitive fine particles, including clays. Potassium silicate stabilizes the fine particles for a substantial period of time thereby substantially preventing formation permeability damage caused by encroachment of aqueous solutions having a distinct ionic makeup into the treated formation.
