Abstract
A method of treating a subterranean well formation wherein a highly viscous thixotropic treating fluid is introduced into the formation. The highly viscous thixotropic treating fluid is formed by combining an aqueous acid solution with an aqueous alkali metal silicate solution whereby a polymerized alkali metal silicate gel is produced followed by shearing of the gel to impart thixotropic properties thereto.
