A wellbore fluid may include an oleaginous continuous phase, one or more magnetic carbon nanoribbons, and at least one weighting agent. A method of performing wellbore operations may include circulating a wellbore fluid comprising a magnetic carbon nanoribbon composition and a base fluid through a wellbore. A method for electrical logging of a subterranean well may include placing into the subterranean well a logging medium, wherein the logging medium comprises a non-aqueous fluid and one or more magnetic carbon nanoribbons, wherein the one or more magnetic carbon nanoribbons are present in a concentration so as to permit the electrical logging of the subterranean well; and acquiring an electrical log of the subterranean well.
