  • Fast dissolving, water soluble, hydrophobically-modified polyelectrolytes
    Patent number: 11332563
    Abstract: Copolymers and compositions containing copolymers having advantageous viscosity, friction reduction, dissolution, pH-stability, and temperature-stability are provided. These copolymers can be used as rheology modifiers for oil field applications.
    Type: Grant
    Filed: July 26, 2019
    Date of Patent: May 17, 2022
    Assignee: Ecolab USA Inc.
    Inventors: Paul Joseph Zinn, En-Wei Lin, Heinrich Enoch Bode, Mario Roberto Rojas, Christopher Steven Popeney, Pious Kurian
  • Salt-tolerant, fast-dissolving, water-soluble rheology modifiers
    Patent number: 11220624
    Abstract: Compounds, compositions and methods of use thereof are provided, the compounds comprising a hydrophobically modified polyelectrolyte comprising a nonionic monomer, an ionic monomer, a monomer having the structure of Formula 1, and a monomer having the structure of Formula 2, wherein R1, R2, R3, R5, R6, and R7 are independently hydrogen, unsubstituted alkyl, substituted alkyl, carbonyl, carboxyl, aryl, or alkaryl; R4 is linear C3 to C30 alkyl; R8 is branched C3 to C30 alkyl; X1 and X2 are independently —C(O)O—, —C(O)NR9—, —O—, —C(R9)2O—, -arylene-, -arylene-C(R9)2O—, -arylene-C(R9)2N(R10)— or -arylene-C(R9)2N+(R10)2—; R9 and R10 is independently hydrogen or a C1 to C4 alkyl; and wherein a molar ratio of the monomer of Formula 1 to the monomer of Formula 2 is from about 1.5:1 to about 15:1. The compounds are useful as viscosifying agents in oil and gas applications.
