  • Polymer gels as flow improvers in water injection systems
    Patent number: 9903169
    Abstract: A water injection system that includes a primary water injection line; an injection fluid supply tank; a high pressure injection pump in fluid communication with the injection fluid supply and primary water injection line for pumping injection fluid in injection fluid supply tank through the primary water injection line; a polymer gel supply tank; and a high pressure chemical injection pump in fluid communication with the polymer gel supply tank and the water injection line configured to pump polymer gel having a viscosity of at least about 50,000 cP (at 20° C. measured using a Bohlin Rheometer CSR 50, cone and plate measuring system CP 4°/40 mm, single shear rate 1/s) in the polymer gel supply tank into the water injection line for mixture with injection fluid is disclosed.
    Type: Grant
    Filed: September 17, 2009
    Date of Patent: February 27, 2018
    Assignees: SCHLUMBERGER NORGE AS, Statoil ASA
