  • Hydrocarbon wells treated with low dosage kinetic hydrate inhibitors
    Patent number: 10392903
    Abstract: Copolymers containing acryloylmorpholine and vinylimidazole, and optionally vinylcaprolactam and/or n-vinyl pyrrolidone, have shown superior results in hydrate inhibition tests at conditions of 7° C. subcooling dosed at 1 vol % based on the water cut of the system fluids. The copolymer product has also passed high TDS (total dissolved solids) brine compatibility tests and secondary property tests including foaming and hot injection tests which make it useful as a kinetic hydrate inhibitor in gas production systems susceptible to the formation of natural gas hydrates.
    Type: Grant
    Filed: July 6, 2018
    Date of Patent: August 27, 2019
    Assignee: Baker Hughes, a GE company, LLC
    Inventors: Howard James Spencer, Ravinder Virdee, Michael P. Squicciarini, Gordon T. Rivers, Marc N. Lehmann
