Abstract
A carbon-based additive may be added to a base fluid to form a fluid composition. The fluid composition may inhibit fouling of the base fluid by any fouling-causing components that may be present in the base fluid where the base fluid is an aqueous fluid, a non-aqueous fluid, and combinations thereof. A carbon-based additive may include solid nanoparticles, nanotubes, graphene, graphene oxide, nanoribbons, nanosheets, and combinations thereof. The carbon-based additive may be present in the fluid in an effective amount to inhibit fouling of the fluid by the fouling-causing components, particularly asphaltenes in a non-limiting example.
