  • Compositions for oil recovery and methods of their use
    Patent number: 8973668
    Abstract: Embodiments of the present disclosure include compositions for use in enhanced oil recovery, and methods of using the compositions for recovering oil. Compositions of the present disclosure include a nonionic, non-emulsifying surfactant having a CO2-philicity in a range of about 1.5 to about 5.0, carbon dioxide in a liquid phase or supercritical phase, and water, where the nonionic, non-emulsifying surfactant promotes a formation of a stable foam formed of carbon dioxide and water.
    Type: Grant
    Filed: September 5, 2014
    Date of Patent: March 10, 2015
    Assignee: Dow Global Technologies LLC
    Inventors: Aaron W. Sanders, Keith P. Johnston, Quoc Nguyen, Stephanie Adkins, Xi Chen, Ed G. Rightor
