Low-viscosity drag reducers, systems for delivering low-viscosity drag reducers, and methods of making low-viscosity drag reducers are disclosed. The low-viscosity drag reducers have a viscosity less than 350 cP at a shear rate of 250 secand a temperature of 60&#xb0; P. This low-viscosity allows the drag reducers to be delivered through a long and relatively small diameter conduit of a subsea umbilical line without an unacceptable level of pressure drop or plugging of the conduit. The low-viscosity drag reducers can be delivered to a subsea flowline carrying fluids produced from a subterranean formation to 10 thereby provide significant drag reduction in the flow line.
