摘要：
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.
