Supercritical ${\rm CO}_2$ injection and dissolution into deep brine aquifers allow its sequestration within geological formations. After injection, ${\rm CO}_{2}$ gas phase is buoyancy-driven over the denser aqueous brine, reaching an apparent gravitational stable distribution. However, ${\rm CO}_2$ dissolution in brine propels convection since the mixture is even denser than the underlying brine. This process still needs to be characterised comprehensively. Here, we investigate the irreversible mixing of dissolved ${\rm CO}_2$ in brine through laboratory-scale numerical experiments utilising the Hele-Shaw model (Letelier et al., J. Fluid Mech., vol. 864, 2019, pp. 746–767) and a fully miscible two-fluid system. In this scenario, mixing the less dense fluid – mimicking ${\rm CO}_{2}$ gas phase – with the heavier fluid – representing aqueous brine – catalyses cabbeling-powered convection. Our numerical simulations recover the laboratory results in porous media by Neufeld et al. (Geophys. Res. Lett., vol. 37, issue 22, 2010, L22404) and may explain the scaling law obtained by Backhaus et al. (Phys. Rev. Lett., vol. 106, issue 10, 2011, 104501) in Hele-Shaw cells. More remarkably, we show that the mass flux between the two analogue fluids, characterised by the Sherwood number $ {{Sh}}$ , obeys the universal scaling law $ {{Sh}}\sim {{Ra}}\, \vartheta _{scalar}$ , with $ {{Ra}}$ the Rayleigh number and $\vartheta _{scalar}$ the mean scalar dissipation rate. This paper sheds light on the fluid dynamics and solubility trapping in geological carbon sequestration.

“…Deep saline aquifers represent a key sequestration option for CO2 ,however, the four processes described above require significant amount of time, upto 100s of years. A review by Rathnaweera and Ranjith (2020) shows that adding nanoparticles in the injected CO2 can significantly reduce the mixing time as well as prevent back migration of CO2, thus preventing leakages.…”

Carbon capture and sequestration (CCS) is a three-tier process- carbon capture, transport andstorage. The capture consists of pre-combustion, oxy-combustion and post-combustion capture.Transport of CO2 is most viable through pipelines.The biotic CO2storage occurs throughterrestrial or oceanic pathways and can be simulated naturally or artificially. The abiotic/geologicstorage is achieved through sequestering CO2 in depleting/depleted hydrocarbon reserves, indeep saline aquifers or through mineral carbonation. At the district level, 64 out of 641 districts(2013 government reports) accounted for ~ 60% of the total CO2 emissions. Controlling CO2emissions comes with the challenge of sustainable socio-economic growth of the country- ademanding task for the economy. Indian organizations have made international collaborations.India holds a substantial geological sequestration potential in its basaltic rocks, coal seams,depleted oil reserves, soils, deep saline aquifers and sedimentary basins. At this point, no carboncapture and storage / clean development mechanism projects are operational in the country. Thenext 10-15 years would be very crucial for India to attain technological advancement to deploylarge-scale CCS projects.

“…Among these, SiO 2 , Fe 2 O 3 , Al 2 O 3 , TiO 2 , and polymeric nanoparticles are commonly studied for oil field applications. Nanoparticles have been studied to control the CO 2 leakage by the following two aspects . One is that nanoparticle solutions can increase the efficiency of CO 2 storage by decreasing the CO 2 mobility, thereby reducing the CO 2 leakage potentials in reservoirs or deep saline aquifers. , Nanoparticles can also be employed as additional agents for improving the property of cements, , gel systems, biotech, and foams , to control unwanted CO 2 migration …”

Comprehensive Review of Sealant Materials for Leakage Remediation Technology in Geological CO₂ Capture and Storage Process

et al. 2021

Carbon capture and storage (CCS) technology has been widely investigated to decrease the greenhouse effect. Geological CO2 storage sites are targeted mainly on depleted petroleum reservoirs or deep saline aquifers. However, CO2 leakage might take place through wellbores, cap rocks, reservoir fractures, or faults during or after the process of CO2 storage leading to environmental problems. To minimize these hazards, different kinds of sealants have been developed and applied. This review aims to summarize those materials applicable to CO2 leakage remediation. On the basis of the sealing mechanisms and compositions of different sealant materials, they were divided into seven major types: Portland cement, geopolymer cement, resins, biofilms barriers, gel systems, foams, and nanoparticles. For different types of sealants, their application background, chemical and physical properties, CO2 leakage remediation mechanism, impact factors of sealing performance, advantages, and limitations were summarized. Future development directions for these sealant materials are also recommended. To solve the problem caused by the weak acid-resistant performance of Portland cement, anti-CO2 materials should be developed and added to the formulation. Environmentally friendly materials need to be designed to replace some current user-hostile compositions in the geopolymer cement. Moreover, chemicals that can control the geopolymerization process are also required because of the high curing temperature requirement for the recent geopolymer productions. The injectivity of Portland cement and resin limits its application for in-depth CO2 leakage control; however, gels with relatively low viscosity during the injection can be a good alternative, although their thermal stability and strength need to be further enhanced. Biotechnology and nanotechnology are perspectives to be applied in the CO2 leakage control process. Foams with good stability might be used for CO2 leakage remediation in the porous medium without fractures, but their life cycle should be prolonged.
