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.
