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.
Claims10
A corrosion inhibition method, the method comprising:
- introducing a treatment fluid into a subterranean formation, wherein the treatment fluid comprises:
- a plurality of silica nanoparticles grafted with hydrophobic branches and amines;
- and
- an aqueous acid;
- wherein the treatment fluid is injected into the subterranean formation via wellbore tubing located within a wellbore of the subterranean formation, wherein the wellbore tubing comprises steel piping and the plurality of silica nanoparticles inhibits corrosion of the steel piping.
