Abstract
The present invention provides methods of sealing subterranean zones using high density sealing compositions. The methods are basically comprised of introducing a sealing composition into the subterranean zone comprised of a high density aqueous salt solution, a polymerizable monomer and a polymerizable initiator and allowing said sealing composition to form a sealing gel in said zone.
