  • Low density oil-based wellbore fluids and methods thereof
    Patent number: 12595404
    Abstract: A wellbore fluid may include an oleaginous continuous phase; a non-oleaginous discontinuous phase; an emulsifier stabilizing the non-oleaginous phase within the oleaginous phase; a low density material selected and in an amount to result in a specific gravity of the wellbore fluid that is less than 0.83; and at least one rheology modifier selected to suspend the low density material within the wellbore fluid.
    Type: Grant
    Filed: April 8, 2025
    Date of Patent: April 7, 2026
    Assignee: Schlumberger Technology Corporation
    Inventors: Roger Daniloff, Arne Asko, Nicholas Hilbig, Jerome Pic
