More Information
Summary:This invention relates to a composition and use application of aqueous fluidized polymer suspensions of hydroxyethyl cellulose (HEC) suspended in sodium thiosulfate for use in oil field applications such completion fluids, drilling fluids, fracturing fluids and oil well cement slurries as rheology/viscosity modifier and fluid loss reducer for use where the affect on the marine environment is to be minimized. L'invention concerne une composition et une application d'utilisation de suspensions polymères fluidifiées aqueuses de cellulose hydroxyéthylique (HEC) en suspension dans du thiosulfate de sodium destinées à être utilisées dans des applications de champ pétrolifère telles que des fluides de complétion, des fluides de forage, des fluides de fracturation et des coulis de ciment pour puits de pétrole comme un modificateur de rhéologie/viscosité et un réducteur de perte de fluide, à utiliser là où une incidence sur l'environnement marin doit être réduite au minimum.
