A method and composition for a freeze-protected, stabilized polymer drag reducing agent suspension comprises a combination of a drag reducing agent polymer and an aqueous carrier. The carrier comprises a dissolved alcohol, glycol, drol, or glycol ether and a dissolved polysaccharide. The resulting suspension is relatively stable against settling, separation and agglomeration.

L'invention concerne un procédé et une composition permettant d'obtenir une suspension stabilisée à agent de réduction de traînée polymérique combinant un agent de réduction de traînée polymérique et un support aqueux. Le support comprend un alcool, un glycol, un diol ou un éther de glycol dissous et un polysaccharide dissous. La suspension obtenue est relativement stable par rapport à la décantation, à la séparation et à l'agglomération.
