Laure Martin-Al-Khatib has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cement compositions and methods
    Patent number: 11898415
    Abstract: Cement slurries are prepared that comprise water, a hydraulic cement and particles of an oil-absorbent material. The particles are present in an amount sufficient to alter a property of a non-aqueous drilling fluid. The cement slurry is placed in a subterranean well, whereupon the slurry contacts residual drilling fluid on casing and formation surfaces. The oil-absorbent material in the cement slurry may reduce the mobility of the drilling fluid, thereby improving zonal isolation.
    Type: Grant
    Filed: June 28, 2019
    Date of Patent: February 13, 2024
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Anatoly Vladimirovich Medvedev, Dominic Vincent Perroni, Laure Martin-Al-Khatib, Adam Ethan Keilers, Petr Kolchanov

  • Self-repairing cements
    Patent number: 10457848
    Abstract: A self-adaptive cement formulation includes cement, water and thermoplastic block-polymer particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.
