  • Methods for wellbore strengthening
    Patent number: 11535786
    Abstract: A wellbore fluid may include an oleaginous fluid forming a continuous phase; a non-oleaginous fluid forming a discontinuous phase; at least one emulsifier stabilizing an emulsion of the non-oleaginous continuous phase within the oleaginous continuous phase; and at least one viscosifier dispersed into the oleaginous continuous phase in a concentration of at least 4 ppb; wherein upon subjecting the wellbore fluid to shear rate of at least 10,000 s?1, the emulsion is disrupted and the non-oleaginous fluid contacts the at least one viscosifier, thereby solidifying the wellbore fluid.
    Type: Grant
    Filed: November 12, 2019
    Date of Patent: December 27, 2022
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Steven Young, Aaron Blue, Josh Sheldon
