Abstract

A drag-reducing formulation includes a polymer composition and a biodegradable fatty acid ester. In certain embodiments, the polymer composition includes at least one latex polymer. The biodegradable fatty acid ester has a structure of RC(═O) OR, where Ris a C-Calkyl or alkenyl group having between zero to three C═C double bonds and Ris a C-Calkyl or alkenyl group. In another aspect, a method of using a drag-reducing formulation involves the steps of deriving a biodegradable fatty acid from a renewable source and mixing the biodegradable fatty acid ester with a polymer composition having at least one latex polymer to obtain the drag-reducing formulation. The method further involves introducing the drag-reducing formulation at an injection point.
