Nanomaterials have become so popular thanks to new and unique properties differing them from their classic counterparts. One of the nanomaterials which is commonly used nowadays is graphene and its derivatives. This paper demonstrates the results of laboratory-scale experimental works on the influence of ultra highly concentrated single-layer Graphene Oxide (HCGO) on properties of water based-mud (WBM). GO is a mono-layer of sp2-hybridized carbon atoms derivatized by a mixture of carboxyl, hydroxyl and epoxy functionalities. Hydroxyl and epoxy groups are present in the highest concentrations on the surface of graphene oxide (GO) per sp3 hybridized carbon atoms, while the carboxyl and carbonyl groups are mainly found at the layer’s edges, thanks to which GO can be easily dispersed in an aqueous environment. The results of our experimental works show that an addition of ultra highly concentrated single-layer Graphene Oxide (HCGO) modifies the microstructural properties of the fluid. HCGO reduces filtration, even if it is added at a relatively low concentration. The conducted analyses prove that HCGO in biopolymer-based drilling mud with biopolymer XCD reduces the growth of bacteria, fungi and yeasts.
