“…Although cake build up to a certain degree is desirable, the excess formation of the same can result in stuck pipe issue and other drilling problems. Fluid-loss additives are generally used to control this process and avoid potential reservoir damage [14]. Recent literature studies show that ionic liquids can be used prospectively to control this fluid loss.…”

Because of industrialization and modernization, phenomenal changes have taken place in almost all spheres of life. Consequently, the consumption of energy resources and the cases of environmental hazards have risen to an unprecedentedly high level. A development model with due consideration to nature and an efficient utilization of energy sources has become the need of the hour, in order to ensure a sustainable balance between the environmental and technological needs. Recent studies have identified the suitability of ionic liquids (ILs), often labeled as ‘green solvents’, in the efficient utilization of energy resources and activities such as bio-extraction, pollution control, CO2 capture, waste management etc. in an environmentally friendly manner. The advent of magnetic ionic liquids (MILs) and deep eutectic solvents (DESs) have opened possibilities for a circular economic approach in this filed. This review intends to analyze the environmental and energy wise consumption of a wide variety of ionic liquids and their potential towards future.

“…Comparably, the typically employed anion groups of ILs can range from hexafluorophosphate to tetrafluoroborate, octyl sulfate, nitrate, bromide, iodide, and chloride. ILs can be hydrophilic and hydrophobic depending on the structures of cations and anions. , In the past few decades, ILs have gained a lot of attention because of their remarkable physical and chemical properties, such as low vapor pressure, high thermal stability, specific solvating ability, compatibility with organic, inorganic, and polymeric materials, and so forth. − Due to their excellent properties, ILs have found many industrial applications, including chemical separation, metal extraction, dye adsorption, green solvents, nanocomposite preparation, etc. ,− Recently, ILs have been employed for many oil and gas applications, including enhanced oil recovery, CO 2 capture and sequestration, and extraction of heavy oil or bitumen. − In addition, numerous researchers − evaluated the inhibitive properties of ILs and demonstrated their great potential as effective shale inhibitors in WBDFs. In our previous work, the performance of the IL 1-vinyl-3-ethylimidazolium bromide (VeiBr) monomer and its corresponding homopolymers (PV) in inhibiting the swelling and dispersion of clays has been explored .…”

Effect of Alkylation Chain Length on Inhibiting Performance of Soluble Ionic Liquids in Water-Based Drilling Fluids

et al. 2023

This work investigated the effect of the alkyl chain length of soluble methylimidazolium bromide ionic liquids (ILs) on their inhibition performance. The IL with a shorter alkyl chain length showed superior inhibition performance by suppressing clay swelling, mitigating clay dispersion, at room temperature. Particularly, the IL with an alkyl chain length of two (EmBr) reduced the sodium bentonite (Na-BT) swelling degree to 89% and achieved a cutting recovery of 81.9% after being rolled at room temperature, performing the best among all ILs. To systematically analyze the inhibition mechanism of ILs, X-ray diffraction (XRD), ζ potential, and particle size distribution have been carried out. The results revealed that the methylimidazolium with shorter alkyl chain length had better ability to enter the interlayer void by ion exchange and decrease interlayer distance, suppress the electrical double layer of the Na-BT particles and decrease the ζ potential, and promote the aggregation of Na-BT in water. It is also observed that high hot rolling temperature reduced the shale inhibiting performance of all ILs, and ILs with longer alkyl chain length had better ability to prevent cutting disintegration at high temperature. It is attributed to the variation of the hydrophilic characteristic of Na-BT at high temperature where EmBr no longer adsorbed the most on the surface and entered the interlayer voids of Na-BT. This study can be used as a reference to systematically explore the effect of the structure of shale inhibitors on their inhibiting performance and develop effective shale inhibitors.

“…Additionally, the modification of functional groups is also confirmed to enhance the inhibition performances of ILs. Ren et al reported that the hydroxyl group contributed to the imidazole-based ILs to improve the thixotropy of drilling fluids, and its ability to enhance the inhibition properties was weaker than that of the amine group. , Wang et al proposed that the generation of hydrogen bonds between bentonite and amine groups facilitated the adsorption of PIL-NH 2 at the surface of bentonite . Xie et al demonstrated that the increased number of primary amine groups improved the inhibition performances of inhibitors .…”

Investigation of the Effects of Functional Groups on the Inhibition Performances of Imidazolium-Based Bola-Form Ionic Liquids as Novel High-Performance Shale Inhibitors

et al. 2023

View full text Add to dashboard Cite

Ionic liquids (ILs) are considered effective additives to inhibit shale hydration swelling in recent years. The imidazolium-based bola-form ionic liquids (IBFILs) with two positively charged groups and optimal alkyl chain lengths can greatly enhance their electrostatic interaction with clay to improve their inhibition ability. The present study further extends our previous research on IBFILs to investigate the effects of different modified functional groups on the inhibition properties of three novel IBFILs including [C 6 (BIM) 2 ]Br 2 , [C 6 (NBIM) 2 ]Br 2 , and [C 6 (ABIM) 2 ]Br 2 . Then, their inhibition performances are evaluated via immersion tests, linear swelling tests, and hot-rolling recovery tests. The inhibition properties of three novel IBFILs are evidently improved in different degrees, especially for the [C 6 (ABIM) 2 ]Br 2 with amine groups. Then, the inhibition mechanisms are analyzed via contact angle measurements, Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD), particle size distribution measurement, ζ-potential, and molecular electrostatic potential (MEP) distribution. The results reveal that the hydrogen bonding and protonation of amine groups should be responsible for the outstanding inhibition property of [C 6 (ABIM) 2 ]Br 2 , whereas the nitro groups indirectly hinder the coverage of the benzene rings at the clay surface to partially affect the inhibition capacity of [C 6 (NBIM) 2 ]Br 2 . Finally, the proposed mechanisms are further confirmed by molecular dynamics simulations. Our work may provide novel insight into the development and design of efficient IL inhibitors with modified functional groups.
