1. A composition comprising:
an injection fluid; and
an alkyl-modified graphene oxide comprising a one or more alkyl functional group covalently bonded to a graphene core through an oxygen-containing linking group,
wherein the one or more alkyl functional groups is selected from the group consisting of dodecane and octadecane,
wherein the alkyl-modified graphene oxide has a corrosion inhibition efficiency of carbon steel ranging from 89 to 95%, and
the alkyl-modified graphene oxide is included in the injection fluid in a concentration ranging from about 5 ppm to 90 ppm.
