Abstract
A method includes preparing an alkyl-modified graphene oxide, injecting the modified graphene oxide into a well, and inhibiting acid-induced corrosion of a steel surface in the well with the modified graphene oxide. A composition includes an alkyl-modified graphene oxide having one or more alkyl functional group covalently bonded to a graphene core through an oxygen-containing linking group. A method of preparing modified graphene oxide includes mixing graphite powder with an oxidant to provide a mixture, adding the mixture to an acid solution including HSO, HPO, or a combination thereof to provide graphene oxide, and reacting the graphene oxide with an alkyl halide by nucleophilic substitution to provide the alkyl-modified graphene oxide.
