“…In recent years, researchers are focusing on environmentally friendly bio-inhibitors and organic salts (ionic liquids) [15]- [18]. With the properties of containing both cationic and anionic parts and low melting point which is typically recorded below 100 °C, ionic liquids have drawn the significant attention of researchers in utilizing it in various fields [19]- [21].…”

Shale instability due to hydration and swelling is an unavoidable problem during hydraulic fracturing or drilling with water-based fluids. In this study, 1-butyl-3-methylimidazolium chloride (BMIMCl) an ionic liquid was utilized as a clay swelling inhibitor. The performance of BMIMCl was evaluated by the bentonite plate soaking test and linear swelling test. FT-IR and zeta potential test was done to explain the swelling inhibition mechanisms. Moreover, XRD test was conducted for the characterization of bentonite (swelling clay). 2 wt.% BMIMCl reduced the swelling rate of bentonite by 19.38% while the conventional and mostly used inhibitor, 3 wt.% KCl reduced 13.84% compared with distilled water. These results showed that BMIMCl has better inhibitive properties than the most used clay stabilizer, KCl. This inhibitor showed better performance because of the presence of a hydrophilic head and hydrophobic tail in its structure. The hydrophilic positive head helped it to get adsorbed on the bentonite surface, forming hydrogen bonds, and reduced the surface negative charge. On the other side, the butyl chain may be made a hydrophobic shield that prevented water from entering into the interlayer space. The ability of BMIMCl to form bonds with bentonite and water was confirmed by FT-IR analysis. Therefore, BMIMCl has the potential to be an effective shale swelling inhibitor during drilling and hydraulic fracturing operations in the water-sensitive shale formation.

“…Inorganic salts such as KCl, NaCl, CaCl2, and NH4Cl have been shown to be effective in combating hydration and swelling shale formations at concentrations ranging from 2-20 wt% (O'Brien and Chenevert 1973;AlMubarak et al 2015;Gholami et al 2018). Several researchers reported that inorganic salts may cause flocculation of fracturing fluids, which are incompatible with the fracturing fluids at higher concentrations and are harmful to the marine environment (Akhtarmanesh et al 2013;Patel et al 2007;Sehly et al 2015;Zhong et al 2011). On the other hand, the application of surfactants, polymeric, and amine-based inhibitors is limited due to their dependency on temperature and concentration, along with their lower inhibitive performance (Barati and Liang 2014).…”

Water-based fracturing fluids without an inhibitor promote clay swelling, which eventually creates wellbore instability. Several ionic liquids (ILs) have been studied as swelling inhibitors in recent years. The cations of the ILs are crucial to the inhibitory mechanisms that take place during hydraulic fracturing. Individual studies were carried out on several ILs with various cations, with the most frequently found being ammonium and imidazolium cations. As a result, the goal of this study is to compare these two cations to find an effective swelling inhibitor. A comparison and evaluation of the clay swelling inhibitory properties of tetramethylammonium chloride (TMACl) and 1-ethyl-3-methylimidazolium chloride (EMIMCl) were conducted in this work. Their results were also compared to a conventional inhibitor, potassium chloride (KCl), to see which performed better. The linear swelling test and the rheology test were used to determine the inhibitory performance of these compounds. Zeta potential measurements, Fourier-transform infrared spectroscopy, and contact angle measurements were carried out to experimentally explain the inhibitory mechanisms. In addition, the COSMO-RS simulation was conducted to explain the inhibitory processes and provide support for the experimental findings. The findings of the linear swelling test revealed that the swelling was reduced by 23.40% and 15.66%, respectively, after the application of TMACl and EMIMCl. The adsorption of ILs on the negatively charged clay surfaces, neutralizing the charges, as well as the lowering of the surface hydrophilicity, aided in the improvement of the swelling inhibition performance.

“…The stack arrangement of smectite can increase specific surface area and provide space for polymer molecular. Moreover, many adsorption sites in the mineral structure and lots of exchangeable ions provide a good prerequisite for the interaction of the unique crystal structure and the polymer, which broadly expands the application range of polymer/clay hybrids 28–30 . The vast majority of organic inhibitors control mineral expansion in water or other liquid phases by adsorbing, binding, encapsulating, and gelling 16,30 .…”

The logical coherence macro–micro experiments about the anti‐swelling performance of polyetheramine‐230 (PEA‐230) on expansive natural soil are presented in this paper. Further, the expansion of the soil in the solution and water system is considered. Great significance in treating the expansive soil broadens the applied range of polyetheramine‐230. The mechanism is assessed by X‐ray diffraction (XRD) in the state of wet and dry montmorillonite (Mt), XRD of dry clay extracts from the soil, zeta potential measurement, thermogravimetric analysis, and scanning electron microscopy. The results prove the significant effect of controlling the expansion of expansive soil. PEA‐230 strongly adsorbs on the surface of soil particles and intercalates into the layer structure. Further, the PEA‐230/soil hybrids can be judged as usable engineering soil with low expansion characteristics. Additionally, the concentration of PEA‐230 controls the treatment effect, and 1 wt% PEA‐230 is a proper concentration to treat the expansive soil. In particular, PEA‐230 has excellent characteristics such as small molecular weight, good water solubility, and good stability. Thus PEA‐230 can be regarded as a great agent to treat in‐situ expansive soil.
