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. Cette invention concerne des procédés de traitement d'une formation souterraine comprenant l'utilisation d'un fluide de traitement comprenant un fluide à base de saumure et un polysaccharide carboxylé anionique. Le fluide à base de saumure comprend une concentration de sel dans la plage d'environ 30000 ppm à saturation et un pH dans la plage d'environ 4 à environ 8, et le polysaccharide carboxylé anionique est présent dans la plage d'environ 0,05 à environ 2 % en poids du fluide de traitement, ledit fluide de traitement pouvant être introduit dans une formation souterraine.
