The development of sustainable, cost-efficient, and high-performance nanofluids is one of the current research topics within drilling applications. The inclusion of tailorable nanoparticles offers the possibility of formulating water-based fluids with enhanced properties, providing unprecedented opportunities in the energy, oil, gas, water, or infrastructure industries. In this work, the most recent and relevant findings related with the development of customizable nanofluids are discussed, focusing on those based on the incorporation of 2D (two-dimensional) nanoparticles and environmentally friendly precursors. The advantages and drawbacks of using 2D layered nanomaterials including but not limited to silicon nano-glass flakes, graphene, MoS 2 , disk-shaped Laponite nanoparticles, layered magnesium aluminum silicate nanoparticles, and nanolayered organo-montmorillonite are presented. The current formulation approaches are listed, as well as their physicochemical characterization: rheology, viscoelastic properties, and filtration properties (fluid losses). The most influential factors affecting the drilling fluid performance, such as the pH, temperature, ionic strength interaction, and pressure, are also debated. Finally, an overview about the simulation at the microscale of fluids flux in porous media is presented, aiming to illustrate the approaches that could be taken to supplement the experimental efforts to research the performance of drilling muds. The information discussed shows that the addition of 2D nanolayered structures to drilling fluids promotes a substantial improvement in the rheological, viscoelastic, and filtration properties, additionally contributing to cuttings removal, and wellbore stability and strengthening. This also offers a unique opportunity to modulate and improve the thermal and lubrication properties of the fluids, which is highly appealing during drilling operations.

“…The preparation procedure of 4% calcium bentonite mud was as follows: Accurately measure 1 L tap water into the mud preparation barrel, then 2 g Na2CO3 and 40 g calcium bentonite were added to the mud barrel, and the resulting solution was stirred at 25 ℃ for 2 h, and then placed it at room temperature for 24 h for use [12]. The preparation procedure of 1% sodium bentonite mud was as follows: Accurately measure 1 L tap water into the mud preparation barrel, then 5 g NaOH and 100 g sodium bentonite were added to the mud barrel, and the resulting solution was stirred at 25 ℃ for 2 h, and then placed it at room temperature for 24 h for use [13]. When drilling fluids experiments were conducted, the required quantity of additive was added to the base mud under stirring at high speed for 20 min.…”

Based on its good water solubility, temperature resistance and environmental protection, oligosaccharides are widely used in food and beverage, baking and medical care. In view of the poor lubrication performance of drilling fluid in ultradeep wells, long horizontal wells and highly deviated wells, and the problems of environmental protection and temperature resistance faced by drilling fluid lubricants, its application is limited. Therefore, in order to reduce its limitations and improve its application, it is necessary to study oligosaccharides. Using vegetable gum rich in oligosaccharides as raw materials, oligosaccharide CQ01 high-performance lubricant can be developed, and its action efficiency in drilling fluid can be experimentally investigated. High performance drilling fluid lubricant meeting the requirements of environmental protection and drilling engineering can be developed, and its lubrication performance, temperature resistance and compatibility can be evaluated in laboratory experiments. The results show that oligosaccharide CQ01 has multiple effects of increasing viscosity and cutting, reducing filtration and improving the lubricating performance of drilling fluid. CQ01 lubricating fluid with low content of oligosaccharide has good adaptability to drilling bentonite. The lubrication mechanism of oligosaccharide CQ01 is that the hydrophilic group (- OH) in oligosaccharide CQ01 molecule is adsorbed on the borehole wall rock surface or drilling cuttings surface to form a chemical adsorption film, resulting in the friction surface being separated by the chemical adsorption film to play the role of lubrication.
