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