  • Precipitation prevention in produced water containing hydrate inhibitors injected downhole
    Patent number: 8980798
    Abstract: The precipitation of polymeric kinetic hydrate inhibitors (KHIs) in stored produced water is prevented or inhibited by incorporating a water immiscible solvent therein having a polarity index greater than about 3. The polymeric KHIs whose precipitation is inhibited or prevented include, but are not limited to, hyperbranched molecules, polyvinylcaprolactam, polyvinylpyrrolidone, and the like. Suitable water immiscible solvents include, but are not necessarily limited to, xylene, toluene, kerosene, mineral spirits, trimethylbenzene, cumene, heavy aromatic naphtha, ethylbenzene, polyethylbenzene, naphthalene, and mixtures thereof.
    Type: Grant
    Filed: March 22, 2011
    Date of Patent: March 17, 2015
    Assignee: Baker Hughes Incorporated
    Inventors: Jun Tian, Cheryl R. Bailey
  • Tertiary amine salt additives for hydrate control
    Patent number: 8404895
    Abstract: New tertiary amine salts are useful as gas hydrate inhibitors in oil and gas production and transportation. These tertiary amine salts give very good separation from an emulsion, are economic and have reduced toxicity concerns.
