Drag reducers are a separate type of friction reducer. Typical friction reducers are water soluble and designed to keep fluid in laminar flow which will reduce the amount of power required to move a Newtonian type fluid (such as water). Drag reducers are oil soluble and specifically designed for transporting crude oil down a pipeline. The drag reducer changes the way crude oil flows and similar to a friction reducer reduces the power to move the crude oil resulting in either a larger throughput or reduced pumping power or both.
