Drag reduction using high molecular weight. Moreover, the injection of the high molecular weight, sulfonated polyacrylamide (Magnafloc 1011) into oil–water annular flow in a horizontal acrylic pipe caused a maximum drag reduction of around 50% (Al-Wahaibi et al., 2007).

Low viscosity, high concentration drag reducing agents may be prepared by slowly adding a liquid, non-solvent (e.g. isopropyl alcohol) for a drag reducing polymer (e.g. a polyalphaolefin) to a mixture of the polymer and the solvent (e.g. kerosene) in which the polymer is dissolved. When enough non-solvent is added, the polymer precipitates into fine particles.
