Abstract
A method begins with the step of preparing a drag-reducing additive by mixing a dispersion polymer with a surfactant and a solvent. The method continues with the step of forming a drag-reducing composition by combining the drag-reducing additive with an aqueous treatment fluid. The method further involves the step of injecting the drag-reducing composition into a subterranean formation, a pipeline or a gathering line.
