Title: Hydrocarbon recovery process using an in situ silicate/polymer gel

Abstract

This patent describes a process for treating a porous earthen mix with a silicate/polymer gel. The process consists of two steps. The first step is the injection into the matrix of an undried, water-soluble silicate and a gelling agent selected from water-soluble strong acids or water-soluble salts of strong acids. The second step consists of reacting a mixture of the partially hydrolyzed polyacrylamide, silicate and gelling agent in the matrix to form the silicate/polymer gel in situ.
