Abstract

See full text

Implementations described herein generally relate to a drag reducing agent (DRA) for improving flow of crude oils having high asphaltene content through pipelines. The DRA is a terpolymer having a glass transition temperature (Tg) of 6 degrees Celsius or below. The terpolymer is formed by a first monomer, a second monomer, and a third monomer. The first and second monomers are chosen based on the glass transition temperatures of corresponding homopolymers. The glass transition temperature of the homopolymer formed with the first monomer is at least 120 degrees Celsius higher than the glass transition temperature of the homopolymer formed with the second monomer. The DRA comprised of the terpolymer formed with the second monomer produces softer solids and fewer solids due to the low glass transition temperature of the terpolymer. The softer solids are more easily handled by the pump to keep the injection system clear.
