“…Recent studies have shown that various chemicals, surfactants, and nanofluids can be used to modify the wettability of a geological formation into a more water-wet state for increased CO 2 geo-storage potential. − However, the effect of MO, which is the main pollutant discharged into the environment from various wastewater facilities, on the CO 2 wettability of organic-acid-aged sandstone has not been reported hitherto. In the present study, the influence of various MO concentrations (10–100 mg/L) on the wettability of stearic-acid-aged quartz was investigated under representative sandstone geo-storage conditions.…”

Carbon capture and sequestration are feasible techniques for achieving net-zero carbon emissions. In this respect, the storage capacity and fluid flow dynamics during carbon geostorage are controlled by the wettability of the geo-storage rock. However, as a result of the presence of organic acid contamination in sandstone geo-storage formations, the rock may attain a CO 2 -wet state, which would significantly reduce the CO 2 storage capacity. While nanofluids and surfactants have been recently utilized as wettability modifiers for enhanced CO 2 geo-storage capacity in sandstone formations, the impact of methyl orange (MO) on the wetting behavior of organic-acid-contaminated quartz has not been reported thus far. MO is a toxic dye that is normally discharged in considerable amounts into the environment. In the present study, MO is used for the wettability alteration of quartz substrates, which are representative of sandstone geo-storage formations. The quartz substrates are aged in n-decane/stearic acid solutions (10 −2 mol/L) for 1 week to mimic the real geo-storage conditions. Thereafter, quartz substrates are aged in various MO concentrations (10−100 mg/L) at 50 °C for 1 week. Subsequently, the advancing (θ a ) and receding (θ r ) contact angles of CO 2 /brine on the stearic-acid-aged quartz substrates with and without MO are measured at various pressures (10, 15, and 20 MPa), brine (NaCl) salinities (0, 0.1, 0.2, and 0.3 M), and temperatures (25 and 50 °C), using the pendant drop tilted plate technique. The results show that the hydrophobic surface of stearic-acid-aged quartz becomes hydrophilic in the presence of MO. Moreover, θ a decreases from 97°to 65°, while θ r decreases from 90°to 56°, as the MO concentration is increased from 10 to 100 mg/L. Therefore, to enhance the CO 2 storage capacity and mitigate CO 2 emissions, it is recommended that MO be disposed of in deep underground sandstone geological formations instead of discharging it into the environment.

“…After this, the Khewra sandstone substrates were ionized with a 2 wt % NaCl solution, while the pH was held at 4 by dropwise addition of aqueous HCl, followed by aging with SA/ n -decane solution (10 –2 mol/L) for 7 days at 50 °C. This process increases the adsorption potential of the sample surface and mimicks the natural geological conditions under which the rock is exposed to organic compounds for millions of years. ,,− Finally, the SA-aged Khewra sandstone substrates were aged in various concentrations of MB solution (10–100 mg/L) to examine the wettability reversal for enhanced hydrocarbon potential. The mechanisms of surface treatment with SA and MB are shown schematically in Figure .…”

Significant amounts of hydrocarbon resources are left behind after primary and secondary recovery processes, necessitating the application of enhanced oil recovery (EOR) techniques for improving the recovery of trapped oil from subsurface formations. In this respect, the wettability of the rock is crucial in assessing the recovery and sweep efficiency of trapped oil. The subsurface reservoirs are inherently contaminated with organic acids, which renders them hydrophobic. Recent research has revealed the significant impacts of nanofluids, surfactants, and methyl orange on altering the wettability of organic-acid-contaminated subsurface formations into the water-wet state. This suggests that the toxic dye methylene blue (MB), which is presently disposed of in huge quantities and contaminates subsurface waters, could be used in EOR. However, the mechanisms behind hydrocarbon recovery using MB solution for attaining hydrophilic conditions are not fully understood. Therefore, the present work examines the impacts of MB on the wettability reversal of organic-acid-contaminated Khewra sandstone samples (obtained from the outcrop in the Potwar Basin, Pakistan) under the downhole temperature and pressure conditions. The sandstone samples are prepared by aging with 10 –2 mol/L stearic acid and subsequently treated with various amounts of aqueous MB (10–100 mg/L) for 1 week. Contact angle measurements are then conducted under various physio-thermal conditions (0.1–20 MPa, 25–50 °C, and salinities of 0.1–0.3 M). The results indicate that the Khewra sandstone samples become hydrophobic in the presence of organic acid and under increased pressure, temperature, and salinity. However, the wettability changes from oil-wet to preferentially water-wet in the presence of various MB solutions, thus highlighting the favorable effects of MB on EOR from the Khewra sandstone formation. Moreover, the most significant change in wettability is observed for the Khewra sandstone sample that was aged using 100 mg/L MB. These results suggest that injecting MB into deep underground Khewra sandstone reservoirs may produce more residual hydrocarbons.

“…Rock–fluid interaction plays a vital role as it governs the rock-wetting behaviors and rock-fluid interfacial tensions. ,– The wettability of Western Australian (WA) basalt was altered from water-wet into moderately to fully CO 2 -wet at a pressure of 15 MPa at 323 K . On the contrary, Iceland basalt remained strongly hydrophilic with CO 2 treatment below 500 m depth but became moderately CO 2 -wet at 900 m .…”

Hydrogen geo-storage is a promising technology to achieve net-zero carbon emissions. Basaltic rocks have attracted limited attention, and only limited knowledge of the suitability of the basaltic formations for large-scale hydrogen storage is available. The complex in situ geochemical reaction of basalt−hydrogen is a key factor in evaluating the suitability of basalt for hydrogen storage. This paper investigates the geochemical interactions of hydrogen−basalt− water and evaluates the impact on basalt's physical properties. Basalt samples collected from the CarbFix site in Iceland are treated with hydrogen−water for 108 days under 9.65 MPa at 348 K, and various analytical methods are employed. The results show minor dissolution of plagioclase minerals after hydrogen treatment due to the redox reactions of hydrogen. However, this dissolution behavior might contribute to the precipitation of calcium on the basalt surface. Images obtained from scanning electron microscopy reveal that only the filling of the cracks was removed after the treatment with no obvious crack growth, which resulted in a minor increase in the pores (4%). Contact angle measurements show that the surface wettability remains water-wet after the treatment. A blank nitrogen− DI water test is performed, to reveal the potential reactions between water and basalt, indicating that only minor changes exist. We conclude that the reactivity of basaltic minerals to hydrogen−water injection is low; thus, the suitability of basalt for hydrogen storage is promising. This work can be a suitable experimental framework to assist in evaluating the hydrogen reactivity to basaltic rocks and assessing the suitability for UHS.
