This patent describes a method for treating a subterranean formation. It comprises: preparing a treating fluid composition with or without a particulate agent by admixing an aqueous liquid, a cellulose ether derivative consisting essentially of the reaction product of a cellulose ether with a ceric salt, the reaction occurring under acidic conditions and at a temperature in the range of from about 20{degree} to about 60{degree}C. and a cross-linking agent; and injecting the treating fluid composition into the subterranean formation through a wellbore. This patent also describes a method of treating a subterranean formation. It comprises: preparing a treating fluid composition with or without a particulate agent by admixing an aqueous liquid, a cellulose ether derivative that is chemically modified by reacting under acidic conditions the cellulose ether derivative with a vinyl phosphonic acid and a ceric salt, and a crosslinking agent; and injecting the treating fluid composition into the subterranean formation through a wellbore.
