“…Figure 10 shows an increase in the thixotropic area of gasoil-based drilling muds as a function of the quantity of VG69 organophilic clay. These results confirm the same work published by Msadok et al (2020) which showed that the thixotropy of gasoil-based drilling muds increases with the concentration of organoclay. This behavior could be explained by the increased cohesive forces and interactions of the clay particles reinforcing the three-dimensional structure through the formation of flocs or aggregates of particles (Hammadi et al 2014).…”

“…The rheology modifier for gasoil-based drilling muds is normally controlled by organophilic clay (Ali et al 2020). The addition of organophilic clay offers to oil-based drilling muds a high thermal stability, an ability to swell in an organic medium (gasoil) and a desired rheological properties such as viscosity, high shear thinning behavior, yield stress and thixotropy (Akkal et al 2013;Msadok et al 2020).…”

“…Recently Msadok et al (2020) used the Tunisian clay modified in order to improve the rheological properties of diesel oil drilling muds. It has been shown that the increase in the percentage of clay modified in diesel drilling muds has led to an improvement in their yield stresses.…”

In this study, the impact of VG69 organophilic clay on the rheological properties of gasoil-based drilling muds (invert emulsions) was investigated. The flow curves of gasoil-based drilling muds as a function of the dose of VG69 organophilic clay were analyzed by the Casson model. The addition of VG69 organophilic clay with a quantity range between 0 and 5 g in gasoil-based drilling muds induces an increase in the yield stress and the viscosity at an infinite shear rate of drilling muds. It is also proven that the addition of VG69 organophilic clay leads to an increase in the viscoelastic and thixotropic properties of the drilling muds. The study of the stability of gasoil-based drilling muds by centrifugation showed that for a quantity of VG69 organophilic clay lower than 3 g, the stability of the drilling muds increases and for a quantity of VG69 organophilic clay higher than 3 g, their stability decreases. The results obtained showed that the addition of 3 g of VG69 organophilic clay to the gasoil-based drilling mud increased the yield stress by 230%, the viscosity at an infinite shear rate by 3.4% and it improved the mud stability by 70%.

“…The treatment of clay with the CTAB led to the appearance of two peaks at 2920 cm -1 and 2851 cm -1 assigned to the symmetrical stretching vibration and asymmetrical elongation of CH2 groups from the organic chain of the quaternary ammonium salt incorporated into clay.The CH2 bending vibration mode was inferred by the peak at 1470 cm -1 , confirming the existence of quaternary ammonium ions in the clay interlayer space [24]. The bond OH (1628 cm -1 ) corresponds to water molecules adsorbed on the clay surface [25] (Fig. 4).…”

In this research, Cellulose Nanofibers (NFC) modified with a eutectic of lauric acid (LA) was prepared as a new form-stable phase change material (NFC-LA). Thermal properties of this composite were investigated by Differential Scanning Calorimetry (DSC). The results revealed that the melting temperature and latent heat of NFC/LA were 21.56 °C and 88.5 J/g, respectively; and the super cooling degree for the NFC-LA composite decreased to 13.99 °C when compared to 20.28 °C of the pure lauric acid. Natural clay was purified and modified with Cetyltrimethyl ammonium bromide (CTAB) to prepare organoclay. Through FTIR spectra, we have confirmed that the clay was successfully modified. The PCM-composite was then added to the organoclay to obtain a new composite denoted NFC-LA-OC. this latter was added to cement and was investigated as a reinforcement material in cement mortars for thermal energy storage application. The prepared material can both solve the leakage problem associated to the phase change material, and reduce or even avoid the use of heating and air conditioning systems, which are energy-intensive systems, and therefore reduce energy consumption.
