Patent

CA 2668561

A composition for treating wellbore formations is provided consisting of a hydratable polysaccharide, an anionic surfactant, and an aqueous solvent where the hydratable polysaccharide is soluble in the aqueous solvent. The concentration of the anionic surfactant is sufficient to scavenge greater than about 50%, and preferably greater than 90% of the cations contained in the aqueous solvent. The hydratable polysaccharide is preferably anionic and may be a guar, guar derivative, galactomannan, cellulose, or cellulose derivative. The composition may also be a slurry used for preparing aqueous well treatment fluid. A method is also provided for utilizing the composition for fracturing a formation by pumping the fluid into the formation.

La présente invention concerne une composition de traitement des formations de puits composée d'un polysaccharide hydratable, d'un agent tensio-actif anionique et d'un solvant aqueux, le polysaccharide hydratable étant soluble dans le solvant aqueux. La concentration de l'agent tensio-actif anionique est suffisante pour piéger plus qu'environ 50 %, et de préférence plus que 90 % des cations contenus dans le solvant aqueux. Le polysaccharide hydratable est de préférence anionique et peut être le guar, un dérivé de guar, le galactomannane, la cellulose ou un dérivé de cellulose. La composition peut également être une boue utilisée pour préparer le fluide de traitement de puits aqueux. La présente invention concerne également un procédé destiné à utiliser la composition pour la fracturation d'une formation par le pompage du fluide dans la formation.
