Abstract

Embodiments of the invention relate to methods for making and compositions including aqueous alkali aluminosilicates used for conformance. The aqueous alkali aluminosilicates provide similar reaction characteristics of alkali silicates, and in addition provide enhanced conformance properties due to their ability to crystallize.
