ABSTRACT:
A composition for treating a subterranean formation and a method of treatment. An aqueous gel composition is formed by mixing a carboxylate-containing polymer with a crosslinking agent comprised of chromic carboxylate. Ethylenediaminetetraacetic acid is incorporated as a single-component gel breaker. When introduced into a permeable formation, the solution forms a gel which makes the formation impermeable. After a predetermined period of time the gel breaker breaks the gel to a predetermined degree which restores partial or limited permeability to the formation.
