Abstract: A polymeric surfactant for use in chemical enhanced oil recovery, including a terpolymer of a first non-ionic monomer, a second non-ionic monomer, and an ionic monomer, the first non-ionic monomer being a hydrophilic monomer and the second non-ionic monomer being a hydrophobic monomer, the ionic monomer being in a lower proportion than the first and second non-ionic monomers. A method of preparation of polymeric surfactants.

Abstract: A friction reducer comprising a copolymer of acrylamide, an anionic monomer, a zwitterionic monomer or a cationic monomer, a physical ligand or a chemical ligand, wherein the acrylamide amounts to at least 50% (w/w) of the total monomer content. The friction reducer is useful in hydraulic fracturing operations and is obtained by controlled radical polymerization at a temperature between 30° C. and 70° C. using iodine as polymerization control agent.
