Abstract

The invention concerns guar-free fluids capable of being used in oil mining and containing de-acetylated xanthane gum in the form of a polypentamer, combined with at least one compound increasing the medium ionic strength. The invention also concerns the use, as filtrate reducer with improved properties, of de-acetylated xanthane gum, in the form of a polypentamer, combined with a compound increasing the medium ionic strength and a standard filtrate reducer.
