Abstract: The present invention generally relates to methods and friction-reducers for decreasing the friction of a fluid. More specifically, the method comprises contacting a friction-reducer to reduce the friction of a fluid flowing in a conduit. The friction-reducer comprises an emulsion polymer, comprising polyanion, polycation, and polynonionic monomers, and a highly concentrated salt solution.
