ABSTRACT:
Treatment methods including preparation of an aqueous treatment fluid composition composed of a carboxy modified polymer, a crosslinking agent, and a viscosifying quaternary amine salt, and subsequently introducing the composition into a the formation to treat. The treatment method is particularly useful for fracturing a subterranean formation. The polymer and crosslinker may be premixed and injected into a wellbore, then mixed therein with the quaternary amine salt to treat the formation. In another aspect, the polymer, crosslinker, and quaternary amine salt are mixed, injected into a wellbore, and introduced in the formation for treatment.
