  • Compounds and method for enhanced oil recovery using sulfur surfactants
    Patent number: 10577530
    Abstract: A method of enhanced oil recovery wherein: (a) a flooding composition is delivered into a subterranean reservoir; (b) the flooding composition includes a sulfur surfactant; and (c) the fluid produced from the subterranean reservoir can also be analyzed to determine if the surfactant is present in the fluid. The surfactant preferably includes a sulfonate moiety or other sulfur-containing moiety. The presence of the surfactant in the fluid produced from the subterranean reservoir is preferably determined by X-ray fluorescence spectroscopy, HPLC-AES, or HPLC-ICP.
    Type: Grant
    Filed: August 28, 2019
    Date of Patent: March 3, 2020
    Assignee: INGEVITY SOUTH CAROLINA, LLC
    Inventors: Kimberley D. Macewan, Reinaldo C. Navarrete, Chao Yang
