  • Using colloidal silica as a zonal isolation material and fast path blocker in geological formations
    Patent number: 10538990
    Abstract: A system for blocking fast flow paths in geological formations includes preparing a solution of colloidal silica having a nonviscous phase and a solid gel phase. The solution of colloidal silica is injected into the geological formations while the solution of colloidal silica is in the nonviscous phase. The solution of colloidal silica is directed into the fast flow paths and reaches the solid gel phase in the fast flow paths thereby blocking flow of fluid in the fast paths.
    Type: Grant
    Filed: January 19, 2018
    Date of Patent: January 21, 2020
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: William L. Bourcier, Sarah K. Roberts, Jeffery J. Roberts, Souheil M. Ezzedine, Jonathan D. Hunt
