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.

“…For this drilling environment, under high pressures and temperatures, oil-based drilling fluids have historically been used [Caenn et al, 2014], however, the strengthening of environmental policies has directed the drilling industry towards the use of water-based fluids [Amanullah et al, 2011;Caenn et al, 2014]. Drilling in deep wells, in addition to being expensive [Fitzgerald et al, 2000], has limitations to the traditional water-based drilling fluids [Amanullah et al, 2011;Al-Yasiri and Al-Sallami, 2015], and to reverse this scenario, in the last decade, interest in the adoption of drilling nanofluids has grown [Amanullah et al, 2011;Fitzgerald et al, 2000;Perween et al, 2019;Al-Yasiri et al, 2019].…”

“…Nanoparticles are materials whose size varies from 1 to 100nm [Amanullah et al, 2011;EPA, 2010]. In the last decade, its their application has sought to mitigate problems caused in drilling with water-based fluids, for example, shale stability control [Al-Yasiri et al, 2019;Aftab et al, 2016;Parizad et al, 2018], filtrate control [Barry et al, 2015;Vryzas et al, 2015], improvement of rheological properties Mao et al, 2015], improvement in thermal and electrical conductivity [Ponmani et al, 2014]. Moreover, the use of nanoparticles is economically interesting for drilling fluids, as it requires small amounts of additives to improve the desired property, and the improvement of the fluid results in a lower incidence of problems during operation and consequently shorter operating time [Amanullah et al, 2011].…”

In the last decade, exploration in high temperature and pressure wells has motivated the improvement of drilling fluids with the application of nanoparticles. In this context, nanoclay, the most available of nanoparticles, has been applied in the development of nanofluids, mainly associated with polymers. In parallel, among the polymers used, xanthan gum has been little explored for this purpose. In this work, the interaction between xanthan gum, hydrophobic nanoclay, sodium and calcium chloride and their influence on the rheological parameters of the mixture was evaluated in solution. The influence of temperature and hydration time on the rheological parameters of the mixture was also evaluated. For this purpose, nanoclay was first characterized with XRF, XRD and TGA. Then, a complete factorial design 24 was adopted, varying the concentrations of nanoclay, xanthan, sodium and calcium chlorides. Third, a Doehlert Matrix of the 7x5x3 type was adopted, varying the concentrations of nanoclay, xanthan and temperature, with the concentrations of the constant salts. In the fourth, select the effect of the hydration time on the color rheological parameters. Finally, Conductivity and Potential Zetas of sizes were verified, varying the concentration of the components and the hydration time of the mixtures. It was concluded that the interactions between the components of the mixture do not stabilize; the temperature, the salts have no significant influence on the rheology of the mixture; nanoclay in concentrations not exceeding 5% (m/v) interacts with the Minimum Shear Stress; the rheological parameters stabilize after 96h of hydration.

“…al., 2000). However, drilling fluids, which are primarily responsible for lubricating and cooling drill components, sealing the well wall and raising cuttings to the surface (Caenn et al, 2014), correspond to 25% of operating costs (Khodja et al, 2010) and, given the complexity of the wells in unconventional zones, these fluids need to be improved (Amanullah et al, 2011;Al-Yasiri et al, 2019).…”

With an estimated increasing oil demand in the coming decades, the need to explore non-applicable areas is intensified, and associated with them, before the high exploration costs, the need to improve available technologies. In this sense, in the last decade, the application of nanoparticles to improve drilling fluids has been intensified. In this scenario, montmorillonite nanoclays and xanthan gums were little explored for the development of nanofluids. In this work, the influence of hydrophilic nanoclay on the rheological parameters of xanthan, sodium and calcium chlorides solutions was verified. For this, first, the clay was characterized by XRD, XRF and TGA. Then, maintaining constant the salt and xanthan concentrations, the influence of the variation in the concentration of nanoclay on the rheology of the solution was evaluated. Then, keeping the components concentrations constant, the influence of temperature was verified and then the hydration time on the rheology of the mixture. Finally, to assess the interaction of the mixture, it was verified the Electrical Conductivity and the Potential Zeta, varying the concentration of the nanoclay and the hydration time. It was concluded that: for certain nanoclay concentrations, there is an improvement in the rheology of xanthan solutions; an addition of nanoclay favors rheology in the mixture of xanthan with increased temperature; hydration time does not affect the rheology of the nanofluid; there is interaction between nanoclay and xanthan.
