Abstract: A composition of matter including a mono-facial polymer-grafted graphene particle and an aqueous-based drilling fluid is provided. In the composition, a first side of the graphene particle has a grafted polymer. A method of lubricating a tool surface using the composition of matter is also provided. The method includes providing an aqueous-based drilling fluid, the aqueous-based drilling fluid having a mono-facial polymer-grafted graphene particle, and introducing the aqueous-based drilling fluid into a wellbore such that it contacts a tool surface to form a coated tool. A drilling tool having a mono-facial polymer-grafted graphene particle adhered to its surface is also provided.

Abstract: A composition that includes a polymer-grafted graphene particle and oil-based drilling fluid is provided. At least one side of the graphene particle comprises a grafted polymer. A method of using an oil-based drilling fluid is also provided. The method includes introducing the oil-based drilling fluid into a wellbore and circulating the oil-based drilling fluid during drilling operations. The drilling fluid includes a polymer-grafted graphene particle and oil-based drilling fluid. At least one side of the graphene particle comprises a grafted polymer. The oil-based drilling fluid includes a range of from about 0.01 ppb to 10 ppb of the polymer-grafted graphene particle.
