A method for producing a stabilized polymer drag reducing agent slurry comprising combining a fatty acid wax and a liquid carrier to form a dispersion; pre-treating the dispersion by heating to partially dissolve the fatty acid wax in the liquid carrier; and adding the polymer drag reducing agent thereto, to form a stabilized polymer drag reducing agent slurry. The resulting slurry is relatively stable against settling, separation and agglomeration.

Cette invention concerne un procédé destiné à produire une boue réductrice de trainée à polymère stabilisé, consistant à combiner une cire d~acides gras et un support liquide pour former une dispersion, à prétraiter la dispersion par chauffage pour dissoudre partiellement la cire dans le support liquide, et à y ajouter l~agent polymère réducteur de trainée pour former une boue réductrice de trainée à polymère stabilisé. La boue résultante s~avère relativement stable à l~encontre d~une sédimentation, séparation et agglomération.
