Title (EN) METHODS OF TREATING SUBTERRANEAN FORMATIONS WITH HETEROPOLYSACCHARIDES BASED FLUIDS
(FR) PROCÉDÉS DE TRAITEMENT DE FORMATIONS SOUTERRAINES À L'AIDE DE FLUIDES À BASE D'HÉTÉROPOLYSACCHARIDES
Abstract: front page image
(EN)Disclosed are methods of treating subterranean formations with rapidly hydratable treatment fluids based upon heteropolysaccharides. In particular, the invention relates to treatment methods with fluids containing a heteropolysaccharide, aqueous medium, and an electrolyte, wherein the fluids may further include a gas component, a surfactant and/or an organoamino compound. The fluids exhibit good rheological properties at elevated temperatures, and unusually rapid hydration rates which allows utilizing such fluids without the need of hydration tanks.
(FR)L'invention concerne des procédés de traitement de formations souterraines à l'aide de fluides de traitement rapidement hydratables à base d'hétéropolysaccharides. L'invention concerne en particulier des procédés de traitement à l'aide de fluides contenant un hétéropolysaccharide, un milieu aqueux et un électrolyte, les fluides pouvant également contenir un composant gazeux, un agent de surface et/ou un composé organoamino. Les fluides présentent de bonnes propriétés rhéologiques à des températures élevées, et des vitesses d'hydratation inhabituellement rapides permettant d'utiliser lesdits fluides sans nécessité de réservoirs d'hydratation.
