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 ... -
High-Performance Kinetic Hydrate Inhibition with Poly(N-isopropyl methacrylamide) and Triisopentylamine Oxide─Surprising Concentration-Dependent Results
Ghosh, Radhakanta; Pomicpic, Janronel Calog; Kelland, Malcolm Andrew (Peer reviewed; Journal article, 2023)Kinetic hydrate inhibitors (KHIs) are mostly used to prevent the deposition of gas hydrates in gas and condensate production flow lines. The main component in a KHI formulation is a water-soluble polymer, blended with ... -
Maleic and Methacrylic Homopolymers with Pendant Dibutylamine or Dibutylamine Oxide Groups as Kinetic Hydrate Inhibitors
Kelland, Malcolm Andrew; Pomicpic, Janronel Calog; Ghosh, Radhakanta (Peer reviewed; Journal article, 2022)Kinetic hydrate inhibitors (KHIs) are applied in oil and gas fields to prevent gas hydrate formation, most often in cold subsea flow lines. The main component in industrial KHI formulations is a water-soluble polymer with ... -
Multi-functional Flow Assurance Chemicals: Corrosion and Kinetic Hydrate Inhibition from Maleic Anhydride:N-Vinyl Caprolactam Copolymers and Synergists
Kelland, Malcolm Andrew; Pomicpic, Janronel Calog; Ghosh, Radhakanta; Undheim, Audun (Peer reviewed; Journal article, 2023)Water-based flow assurance issues include corrosion, scale, and gas hydrate formation. Chemical solutions to mitigate these issues usually require separate inhibitors, which sometimes can lead to compatibility difficulties. ... -
Multi-functional oilfield production chemicals: maleic-based polymers for gas hydrate and corrosion inhibition
Kelland, Malcolm Andrew; Pomicpic, Janronel Calog; Ghosh, Radhakanta; Undheim, Camilla; Hemmingsen, Tor; Zhang, Qian; Varfolomeev, Mikhail A.; Pavelyev, Roman S.; Vinogradova, Svetlana S. (Peer reviewed; Journal article, 2021)Several chemical problems can occur during the production of oil and gas through flow lines. This includes corrosion, scale deposition and gas hydrate plugging. Three separate chemicals may be needed to treat these issues. ... -
Non-Amide Polymers as Kinetic Hydrate Inhibitors-Maleic Acid/ Alkyl Acrylate Copolymers and the Effect of pH on Performance
Pomicpic, Janronel Calog; Ghosh, Radhakanta; Kelland, Malcolm Andrew (Peer reviewed; Journal article, 2021)Kinetic hydrate inhibitors (KHIs) have been used for over 25 years to prevent gas hydrate formation in oil and gas production flow lines. The main component in KHI formulations is a water-soluble polymer with many amphiphilic ... -
Nonpolymeric Citramide-Based Kinetic Hydrate Inhibitors: Good Performance with Just Six Alkylamide Groups
Ghosh, Radhakanta; Kelland, Malcolm Andrew (Peer reviewed; Journal article, 2022)The use of kinetic hydrate inhibitors (KHIs) is a well-known method for preventing gas hydrate formation in oil and gas production flow lines. The main ingredient in KHI formulations is one or more polymers with amphiphilic ... -
