Chrystel Cambus-Brunet 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).

  • Patent number: 8371381
    Abstract: Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers.
    Type: Grant
    Filed: May 19, 2010
    Date of Patent: February 12, 2013
    Assignee: Schlumberger Technology Corporation
    Inventors: Nikhil Shindgikar, Jesse Lee, Slaheddine Kefi, Chrystel Cambus-Brunet, Michel Ermel

  • Patent number: 7530408
    Abstract: A method of stabilizing an underground formation surrounding a borehole comprising placing a treatment fluid in the formation, the treatment fluid comprising cross-linkable polymer and a cross-linking agent, and allowing the treatment fluid to gel in-situ, characterized in that after placement of the treatment fluid in the formation, an activator fluid is pumped into the well to bring about cross linking of the polymer to form the gel.
