Recent Advances in Deep Eutectic Solvents as Shale Swelling Inhibitors: A Comprehensive Review

Inhibitors have evolved from their primary function of controlling swelling during hydraulic fracturing processes in shale reservoirs. This study provides a comprehensive review of recent deep eutectic solvent (DES) advancements as inhibitors in swelling inhibition techniques. The swelling inhibitory potentials and mechanisms of DESs have been studied analytically and compared to existing conventional inhibitors. The functional effects of concentration, temperature, and types of DES are explored. Data on the effect of DES on rheology, swelling, zeta potential, shale cutting recovery, surface tension, particle size distribution, XRD, and FTIR analyses are presented. Along with preparation procedures, environmental concerns and applications of DESs in several fields are discussed. This study suggests that DESs are preferable swelling inhibitors due to their inhibitory performance, cost-effectiveness, and environmental friendliness. Moreover, this review includes guidelines and recommendations for selecting and designing DES to inhibit swelling more effectively.

“…Shale hydration is essentially the hydration of the layered clay minerals, including surface hydration and osmotic hydration. , In surface hydration, driven by the surface energy from the shale, water molecules would absorb on the surface of the layered clay mineral crystals. , In the beginning, only water monolayer molecules are absorbed on the crystal surface. Then, the second and subsequent layers absorb the previous water layer by hydrogen bonds.…”

Novel Use of a Superhydrophobic Nanosilica Performing Wettability Alteration and Plugging in Water-Based Drilling Fluids for Wellbore Strengthening

et al. 2022

Severe shale wellbore instability accidents in water-based drilling fluids encourage research and development of new inhibitors and nanoplugging agents. In this work, we synthesized a multifunctional superhydrophobic nanosilica (SA), which could form a hydrophobic film on the shale surface, imparting inhibiting and plugging properties. The composition and surface morphology of SA were characterized, and the results showed that SA was spherical at around 30 nm. The inhibiting performances were evaluated by hot-rolling recovery, linear swelling, and water spontaneous imbibition tests. The plugging performance of SA was appraised by the filtration test with nanofilter paper and pressure transmission tests. The strengthening of shale core mechanical stability properties of SA was also appraised by the uniaxial compressive tests. The results showed that SA performed excellently at inhibiting shale hydration. The recovery rate of shale cuttings at 180 °C reached 64.8%. In addition, due to the low surface energy, SA particles could disperse stably at the nanoscale and perform well at plugging the nanopores and fractures, effectively reducing the filtration loss by 75% compared with the base fluids and limiting the pressure transmission through the shale. The compressive tests showed that after the shale cores were immersed in deionized (DI) water, 2% SA, and 3% aqueous suspensions at 150 °C for 48 h, the compressive strength of the shale cores decreased by 26.69, 3.88, and −2.22%, respectively, proving that SA could effectively alleviate the decrease of shale strength and even increase it at higher concentrations. The mechanism research showed that SA could decrease the surface energy of the shale from 81.86 to 1.15 mN/m and change its wettability to superhydrophobic, significantly inhibiting surface hydration. By changing the wettability, SA reversed the direction of the capillary force to offset the osmotic pressure, thereby decreasing the amount of water entering the shale through the nanopores or fractures and effectively inhibiting osmotic hydration. In addition, SA could accumulate on the surface of the shale and form a dense superhydrophobic membrane, providing proper plugging properties.

“… 2 As the main component of shale, clay minerals, mainly composed of montmorillonite, will expand when they encounter water, causing wellbore safety problems. 3,4 Although clay minerals in shale are not hydrated in oil-based drilling fluids (OBDFs), OBDFs have problems such as high cost, non-biodegradability, and being harmful to environmental health. 5 Nowadays, relevant environmental protection agencies are becoming more and more strict with treatments that are harmful to the environment, and finally water-based drilling fluids (WBDFs) have been selected for drilling.…”
