Abstract
A method of mitigating corrosion of downhole articles includes mixing a plurality of nanoparticles into a first downhole fluid to form a nanoparticle fluid. The method also includes exposing a surface of a downhole article in a wellbore to the nanoparticle fluid. The method further includes disposing a barrier layer comprising a portion of the nanoparticles on the surface of the article and exposing the surface of the downhole article to a second downhole fluid, wherein the barrier layer is disposed between the second downhole fluid and the surface of the article.
