Abstract

Nanomaterials such as nano-silica and nano-graphene have been studied and used as additives for drilling fluids or petro-chemicals in the oil and gas industry. In particular, nano-graphene oxide as a single layer of graphite has a honeycomb lattice structure of carbon atoms consisting of oxygen-containing functional groups outside the ring such as hydroxyl, epoxyl, and carboxyl. This structure helps nano-graphene oxide in the polar media, especially water, and also allows expanding the applications of this material in water-based drilling fluid. This study presents a method of nano - graphene oxide synthesis from natural graphite material, and researches application capabilities of this material as a fluid-loss-control additive for reducing filtrate and stabilising the thermal properties of water-based drilling fluids when used at high temperatures up to 150oC.
