摘要: An aqueous polymeric gel-forming composition which slowly crosslinks to form stable gels for plugging highly permeable zones in subterranean oil-bearing formations. The comprises an solution of a water-dispersible polymer present viscosifying amount and crosslinking agent effective cause gelation the mixture aldehyde member selected from group consisting phenolic esters, naphtholic halogenated esters esters.
