description	The invention discloses a method of treating a wellbore by providing an aqueous mixture of a hydrated polysaccharide with a salt; adding to the mixture a cross-linking agent for cross-linking the hydrated polysaccharide, wherein the cross-linking agent comprises a zirconium compound, glutamic acid, and a polyol; pumping the aqueous mixture of the hydrated polysaccharide and the cross-linking agent into the wellbore; and cross-linking the hydrated polysaccharide. L'invention porte sur un procédé de traitement d'un puits de forage par l'obtention d'un mélange aqueux d'un polysaccharide hydraté avec un sel ; l'ajout au mélange d'un agent de réticulation servant à réticuler le polysaccharide hydraté, l'agent de réticulation comprenant un composé du zirconium, de l'acide glutamique et un polyol ; le pompage du mélange aqueux du polysaccharide hydraté et de l'agent de réticulation dans le puits de forage ; et la réticulation du polysaccharide hydraté.
