In this study; it is aimed to improve the rheological properties of Na-Bentonite water based drilling muds (WBDM) by graphene, graphene oxide (GO) and graphene oxide functionalized with gold nanoparticles (AuNPs/GO) at 0.0005-0.01 (% w/v) ratios. For this purpose, firstly; AuNPs, graphene, GO and AuNPs/GO were synthesized, and then characterized by SEM, TEM, EDX, RAIRS and XPS. Synthesized and characterized nanomaterials were added to WBDM at a rate of 0.0005% to 0.01% (w/v), and finally, rheological and filtration loss analyzes of water based drilling muds containing nanomaterials were carried out according to American Petroleum Institute Standards. As a result of this study, in which nanomaterials were used to improve the properties of water based drilling mud; plastic viscosity (PV), apparent viscosity (AV), yield point (YP), gel strength (10 s and 10 min), respectively; it was determined that it increased by 67%, 44%, 44%, 67% and 50%, and at the same time, the filtration loss value decreased by 14%.
