Abstract
Aluminum carboxylate drag reducing agents are described herein. These materials are useful to reduce drag in hydrocarbon fluids and multiphase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming. In one non-limiting embodiment, an aluminum monocarboxylate is reacted with at least one carboxylic acid in situ. In another non-limiting embodiment, the aluminum carboxylate is introduced as a dispersion in a solvent such as paraffin oil. The drag reducing additives include aluminum dicarboxylates such as aluminum dioctoate, aluminum distearate, aluminum octoateoleate, aluminum octoatestearate, aluminum stearateoleate, hydroxyaluminum bis(2-ethylhexanoate) and mixtures thereof.
