“…1b). Therefore, as mentioned previously, the clay mineral is stabilized through the two mechanisms, cation exchange and hydrogen bonding creation (Parvizi Ghaleh et al 2020). In other words, the inhibition behavior of thiamine is maintained, despite its structure is broken.…”

This study aims at evaluating the performance of thiamine as a new eco-friendly shale inhibitor in water-based drilling fluids (WBDFs). The evaluation experiments include sedimentation, bentonite inhibition, filtration, zeta potential, thermal gravimetric analysis, scanning electron microscopy, X-ray diffraction, shale cuttings recovery, linear swelling and Fourier transform infrared spectroscopy (FTIR). The performance of thiamine was compared to potassium chloride. In contrast to deionized water, the aqueous solution of thiamine exhibited greater power to inhibit montmorillonite (Mt) dispersion, much more Mt loading capacity (280 g/L) and fluid loss, lower Mt mass loss, larger aggregated Mt particles, lower interlayer space of the Mt particles, less shale cuttings disintegration and lower linear swelling. Adsorption of thiamine on Mt led to a significant shift in the value of zeta potential (from −17.1 to +8.54 mV). Thiamine demonstrated superior inhibitive performance than potassium chloride. FTIR analysis confirmed that thiamine is adsorbed on Mt particles. The compatibility test revealed the compatibility of thiamine with conventional WBDF additives. It was concluded that the main probable inhibition mechanisms of thiamine are the cation exchange and Mt surface coating. In view of its prominent inhibition capacity and great environmental acceptability, thiamine is a promising inhibitor for drilling in water-sensitive formations.

“…As it was mentioned above, thiamine is stable under acidic conditions. To better understand the underlying mechanism, the behavior of Mt in deionized water and aqueous solution of thiamine is indicated graphically by Parvizi Ghaleh et al (2020). Thiamine has an N + cation in its structure.…”

“…The reported mechanism of clay swelling inhibition was the intercalation of CTAB into the interlayer spacing of montmorillonite. Ghaleh et al recently explored the adsorption of thiamine onto sodium montmorillonite, resulting in clay swelling inhibition . The use of ILs as a clay swelling inhibitor has been seldom detected.…”

“…Ghaleh et al recently explored the adsorption of thiamine onto sodium montmorillonite, resulting in clay swelling inhibition. 14 The use of ILs as a clay swelling inhibitor has been seldom detected. Because it contains both cations and anions, it is expected that it may enhance the inhibitory potential by lowering the extent of hydration of the clay minerals.…”

Ionic Liquids as Clay Swelling Inhibitors: Adsorption Study

et al. 2022

This study investigates the inhibition performance of ionic liquids (ILs) on clay (montmorillonite) swelling and the possible inhibition mechanism. The adsorption of various types of ILs in swelling clay was studied by adsorption isotherms, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). Experiments were conducted at different concentrations for different types of ILs. Moreover, the adsorption isotherms were modeled using Langmuir, Freundlich, Sips, Redlich–Peterson, and Fritz–Schlunder models. The type of model fitting was used to evaluate the clay stability in terms of monolayer and multilayer adsorption. The experimental results revealed that the ILs’ adsorption strongly depends on the IL structures and concentrations. The results showed that in aqueous solutions, IL molecules have a strong interaction with swelling clay minerals, causing the intercalation between the interlayer of the clay minerals and ILs. XRD results revealed that the intercalation of ILs between the layers of clay is related to the enlargement in basal (d) spacing. The efficacy of the adsorption process was also demonstrated by the specific bands of the ILs on the infrared spectra. The relative amount of the IL adsorbed on the clay surface was in the order of 1A3MI-CN < 1B1MP-Br < TBP-MS < TEA-TFMS. Error metrics consisting of the coefficient of determination (R 2), mean square error (MSE), and mean absolute error (MAE) was employed as a criterion for a better fit of the adsorption model of ILs. Sips and Redlich–Peterson adsorption models show a reasonable fitting for all ILs in this study.
