  • Nanoparticle-densified Newtonian fluids for use as cementation spacer fluids and completion spacer fluids in oil and gas wells
    Patent number: 8499837
    Abstract: Cement spacer fluids may be densified for use in conjunction with drilling fluids and cement slurries for cementing operations involving oil and gas wells, wherein such densifying is done via the addition of nanoparticles to the spacer fluid. The disclosure is directed to analogous methods of densifying completion spacer fluids using added nanoparticles and to systems for implementing the use of such nanoparticle-containing compositions in well cementing operations.
    Type: Grant
    Filed: March 29, 2010
    Date of Patent: August 6, 2013
    Assignee: Chevron U.S.A. Inc.

  • NANOPARTICLE-DENSIFIED NEWTONIAN FLUIDS FOR USE AS CEMENTATION SPACER FLUIDS AND COMPLETION SPACER FLUIDS IN OIL AND GAS WELLS
    Publication number: 20100243236
    Abstract: The present invention is directed to methods for densifying cement spacer fluids for use in conjunction with drilling fluids and cement slurries for cementing operations involving oil and gas wells, wherein such densifying is done via the addition of nanoparticles to the spacer fluid. The present invention is also directed to analogous methods of densifying completion spacer fluids using nanoparticles, to Newtonian fluid compositions resulting from any such fluid densification, and to systems for implementing the use of such compositions in well cementing operations.
