  • FUNCTIONALIZED OLEFIN OLIGOMERS
    Publication number: 20220380658
    Abstract: The present disclosure provides a method of treating a hydrocarbon-containing reservoir. The method involves introducing into the reservoir a surfactant composition. The surfactant composition includes an alpha olefin sulfonate or an isomerized olefin sulfonate. The alpha olefin sulfonate or the isomerized olefin sulfonate is synthesized by i) oligomerizing a monomer comprising a C3 to C6 mono-olefin to form an oligomerization product and ii) sulfonating the oligomerization product.
