ABSTRACT:
Liquid containing composition, and the transport of pumping thereof are disclosed, which compositions achieve maximum fluid friction reduction properties at low concentration of a drag reducing agent such as less than 0.015% by weight and preferably less than 0.01% by weight. The drag reducing agent is a polymer of 2-acrylamido-2-methylpropanesulfonic acid. Finely divided solids, such as coal, may be suspended therein.
