Abstract:
1. A method of servicing a wellbore, the method comprising: forming a nano-dispersion well servicing fluid by blending an aqueous base continuous phase and nanoparticles comprising at least one material chosen from aluminum oxides, aluminum hydroxides, aluminum hydroxyoxides, zirconium oxides, zirconium hydroxides, and zirconium hydroxyoxides, the concentration of the nanoparticles being greater than 0.5% by weight based on the total weight of the nano-dispersion well servicing fluid, the nanoparticles having a crystallized size of 100 nm or less in diameter prior to being dispersed, the nanoparticles forming a dispersion in the aqueous base, and the nanoparticles carrying a charge resulting in a Zeta potential in the well servicing fluid; decreasing the Zeta potential of the well servicing fluid closer to zero and thereby increasing the viscosity; and introducing the well servicing fluid with the increased viscosity into the wellbore.
