“…NP concentration of 0.9 wt% shows a significant improvement in the viscosity, hence it has been considered for the cuttings transport investigations. The effective dispersion ability of NPs within the fluid structure could be the responsible for viscosity improvement 46 . Figure 6 depicts fluid viscosity distribution in the model through a cross‐sectional view of the viscosity contour.…”

Cuttings transportation from the drill bit, through the annulus, to the surface is one of the most important functions performed by drilling fluid. The prediction of drilling fluid's performance to transport cuttings in the annulus is very complex task due to the presence of numerous parameters. Nanoparticles (NPs) have been recently introduced into drilling fluid to engineer its properties and enhance its performance. Nevertheless, the lifting capacity has not been sufficiently investigated. The understanding of the influence and the mechanisms responsible for the improvement in cuttings transport process can further advance the application of NPs for drilling fluids. Computational fluid dynamics (CFD) is widely used as a numerical technique in handling complex multiphase flow problems in different operational conditions. The present work has taken the advantages of CFD to computationally analyze the influence of NPs and the effects of various parameters such as drilling fluids rheology, flow rate, pipe rotation, cuttings density, shape, concentration, and drilling fluids-cuttings particle coupling regimes on the cuttings transport in a vertical wellbore. The CFD simulation is carried out by using transient solver of ANSYS-FLUENT commercial code. The dense discrete phase model is used to overcome the main shortcomings of previous Eulerian based approaches. Good agreement has been achieved between the simulation and the published experimental results. It showed that the fluid viscosity and cuttings transport process can be significantly enhanced by adding nanomaterials to the fluid, and the process is highly influenced by cuttings characteristics such as in situ concentration, shape, and density.

The emerging nanoscience, nanotechnology and nanomaterials can be used for various industrial applications to enhance reliability, performance, stability and functional capability. Their application in the design and development of tools and materials used in oil and gas industry for extreme drilling conditions could overcome the current limitations of conventional tools and the various fluid systems used by the industry. The functional limitations such as poor physio-chemical stability in acid gas environment, frequent mechanical failure and malfunctioning in complex geological environment, thermal degradation in high temperature environment, etc. of currently used conventional tools and fluid systems are associated with extreme operating conditions due to a shift of the drilling operation from low risk to high risk geological environments, onshore to offshore locations, shallow water to deep water environment, etc. The progressive shift to increasingly higher risk operating environments is unavoidable as the energy demand of global community has increased manifold and is expected to increase further in future. Moreover, the probability and likelihood of finding easy oils and gas resources in low risk areas are diminishing quickly. That is why the oil and gas companies are constantly shifting to extremely challenging environments to meet the global energy demand. This is reflected by the expansion of drilling activities in complex geological areas, deep water environments, extreme-HPHT environments, etc. As the current tools and equipment and also the additives and chemicals often fail and/or lose their functional ability due to the detrimental effect of exposure of extremely harsh conditions, the industry needs tools and equipment, chemicals fluid additives that are highly reliable, chemically resistive, thermally and mechanically stable to ensure safe and trouble free drilling operations. It has been demonstrated in several fields of study that nanostructured materials and additives exhibit improved mechanical, chemical, thermal, electrical and tribological properties that can significantly increase the stability and durability of the tools and equipment along with the chemical and thermal stability of additives required for high performance fluid design. This review article captures the recent developments about the application of nanomaterials in the design and development of tools, equipment, additives, chemicals and smart materials to overcome current and future technical challenges of the oil and gas industry. Finally, the conventional of rule of mixtures of composite materials design and the current nanotechnology-based research conducted by various researchers have been highlighted to demonstrate potential of nanotechnology to enhance the physical, mechanical, chemical and thermal property of tools, equipment and various fluid systems used by the oil and gas industry.

Development of modern electronic devices demands a creation of effective cooling systems in the form of active or passive nature. More optimal technique for an origination of such cooling arrangement is a mathematical simulation taking into account the major physical processes which define the considered phenomena. Thermogravitational convection in a partially open alumina-water nanoliquid region under the impacts of constant heat generation element and heat-conducting solid wall is analyzed numerically. A solid heat-conducting wall is a left vertical wall cooled from outside, while a local solid element is placed on the base and kept at constant volumetric heat generation. The right border is supposed to be partially open in order to cool the local heater. The considered domain of interest is an electronic cabinet, while the heat-generating element is an electronic chip. Partial differential equations of mathematical physics formulated in non-primitive variables are worked out by the second order finite difference method. Influences of the Rayleigh number, heat-transfer capacity ratio, location of the local heater and nanoparticles volume fraction on liquid circulation and thermal transmission are investigated. It was ascertained that an inclusion of nanosized alumina particles to the base liquid can lead to the average heater temperature decreasing, that depends on the heater location and internal volumetric heat generation. Therefore, an inclusion of nanoparticles inside the host liquid can essentially intensify the heat removal from the heater that is the major challenge in different engineering applications. Moreover, an effect of nanosized alumina particles is more essential in the case of low intensive convective flow and when the heater is placed near the cooling wall.
