• 5-Methyl-3-vinyl-2-oxazolidinone-Investigations of a New Monomer for Kinetic Hydrate Inhibitor Polymers 

      Kelland, Malcolm Andrew; Dirdal, Erik Gisle; Ghosh, Radhakanta; Ajiro, Hiroharu (Peer reviewed; Journal article, 2022)
      Kinetic hydrate inhibitors (KHIs) are polymers used in a chemical method to prevent gas hydrate plugging of oil and gas production flow lines. The main ingredient in a KHI formulation is one or more water-soluble amphiphilic ...
    • Kinetic Hydrate Inhibitors─Which is Best, Block or Statistical Copolymers? 

      Kelland, Malcolm Andrew; Destarac, Mathias; Coutelier, Olivier; Dupre-Demorsy, Alexis; Ando, Tsuyoshi; Ajiro, Hiroharu; Dirdal, Erik Gisle; Pomicpic, Janronel (Peer reviewed; Journal article, 2024)
      Kinetic hydrate inhibitors (KHIs) have been used for nearly 30 years to prevent gas hydrate formation in oil and gas production flow lines. The main component in KHI formulations is one or more water-soluble polymers. ...
    • Oxyvinylenelactam Polymers-A New Class of Lactam-Based Kinetic Hydrate Inhibitor Polymers 

      Kelland, Malcolm Andrew; Ghosh, Radhakanta; Undheim, Audun; Dirdal, Erik Gisle; Ajiro, Hiroharu (Peer reviewed; Journal article, 2022)
      The deployment of kinetic hydrate inhibitors (KHIs) is a chemical method for the prevention of gas hydrate plugging in gas, condensate, and oil production flow lines. Polymers made using the monomer N-vinylcaprolactam ...
