Zusammenfassung:Methods of treating a subterranean formation including providing a treatment fluid comprising a brine base fluid and an anionic carboxylated polysaccharide. Wherein the brine base fluid comprises a concentration of salt in the range of from about 30,000 ppm to saturation and a pH in the range of from about 4 to about 8, and wherein the anionic carboxylated polysaccharide is present in the range of from about 0.05% to about 2% by weight of the treatment fluid. The treatment fluid may be introduced fluid into a subterranean formation.
