Abstract

Silica nanoparticles grafted with hydrophobic branches and amines may be used to mitigate corrosion. For example, method for mitigating corrosion downhole may include introducing a treatment fluid into a subterranean formation, wherein the treatment fluid includes: an aqueous acid and a plurality of silica nanoparticles grafted with hydrophobic branches and amines. Examples of amines may include C2 to C18 amines. Examples of hydrophobic branches may include C2 to C18 alkyl groups.
