Effects of imidazolium- and ammonium-based ionic liquids on clay swelling: experimental and simulation approach

Abstract: 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… Show more

“…KCl is used as a conventional shale inhibitor and has been obtained from Sigma Aldrich, Subang Jaya, Malaysia. 1-ethyl, 3-methyl imidazolium chloride (EMIM-Cl) > 98% is chosen because it has been found to give excellent results as drilling fluid additives for modifying mud rheology and shale inhibition [47]. KCl and EMIMC-Cl will be used for comparison purposes for shale inhibition traits of NADES.…”

“…In a study by Rahman et al (2022), the researchers utilized tetramethylammonium chloride (TMACl) and 1-ethyl-3-methylimidazolium chloride (EMIMCl) in drilling mud and found that they led to 23.40% and 15.66% reductions in linear swelling, respectively [18]. Rizwan et al (2021) found that using Trihexyltetradecyl phosphonium bis(2,4,4-trimethyl pentyl) phosphonate-based ionic liquid resulted in 12.3% shale inhibition compared to water.…”

“… 33 Ionic liquids (ILs) have recently been employed as fracturing fluid additives to inhibit clay swelling. 34 Several studies have been done to explain the inhibition performance, mechanisms, and effects of different moieties of ILs as clay swelling processes. 35 However, a recent study has shown that ILs based on imidazolium are costly, hazardous, nondecomposable, and needed complicated processes and apparatuses to prepare.…”
