“…On the other hand, the NA effect on the parameter is negative, that is, clay has contributed negatively on the rheological parameter, which contradicts previous studies that show a positive contribution to this rheological parameter, especially with the increase in the clay concentration in the suspension [Shakib et al, 2016;Abu-Jdayil, 2011;Bailey and Leall, 1994].…”

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.

“…[12][13][14] In addition, as an important environmental protection additive for water based drilling fluids, nanoparticles show a good application prospect in petroleum industry, the benefits of nanofluids in water based drilling fluids include improvement of fluids rheological properties, reductions in filtration loss and friction coefficient, increase of the rate of heat transfer, shale stability improvement, and inhibition of gas hydrate formation. [15][16][17][18][19][20] Tree gums are natural polysaccharides consisted with multiple monosaccharides such as arabinose, galactose, glucose, mannose, xylose and uronic acids. Carob bean gum (CBG), Prunus persica (L.) Batsch, is a branched acidic heteropolysaccharide extracted from the secretion of a rosaceae plant (Figure 1).…”

Excessive exploitation of non-renewable energy and environmental damage have forced people's scientific research turn to inexhaustible nature plants. In this work, carob bean gum (CBG) was modified using sodium chloroacetate as the modifier to enhance its solubility and efficiency in water based drilling fluids. The modification conditions were discussed through single factor test and screened as follows: the mass ratio of sodium chloroacetate to CBG was 20.0g/100g with pH 12 at the temperature of 50°C for 6 h. The rheological property and filtration loss of carboxymethylated carob bean gum (CCBG) treated drilling fluids were tested, which demonstrated more excellent rheological property and lower filtration loss than that of CBG. The inhibitive property of CCBG was evaluated by using Na-Bentonite (Na-MMT)-swelling tests and mud ball immersing tests, which showed that CCBG performed a high inhibitive and anti-caving capacities in water-based drilling fluids.

In drilling fluids, NA was applied to improve rheological and filtrate properties in fluids based on bentonite and polymeric additives (Shakib et al, 2016;Cheraghian (2017)); Jain and Mahto (2015) added NA to polyacrylamide to inhibit shale; Hassani and Ghazanfari (2017) applied NA for the development of colloidal gas aphrons for application in drilling fluids; Vipulanandan and Mohammed (2015) applied NA in bentonite based sludge to improve rheology and electrical resistivity. However, the application of NA to the perfection of drilling fluids is still discreet when compared to other nanoparticles or in other segments.…”

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.
