A new ionic liquid triethylammonium carboxylate [(C2H5)3NH][RCOO] (where R is fatty acid groups of coconut oil) was synthesized from fatty acid of coconut oil and triethyl amine. Graphene oxide (GO) was synthesized from graphite via modified Hummers method then was reduced to form reduced graphene oxide. The products were characterized and confirmed by FT-IR, XRD and NMR analysis. Friction-reducing additives was prepared from by dispersed reduced graphene oxide in [(C2H5)3NH][RCOO] (0.1%). Friction-reducing properties of materials were measured by GOST P56946-2016 (equivalent to ISO 13500:2008). The results show that using graphene and liquid triethylammonium hydrogen carboxylate lead to increase in the friction-reducing property of based oil in drilling fluid and mixture of them showed highest capacity of increasing the friction-reducing property of drilling fluid.
