Carbon capture, utilization, and storage (CCUS) technology has shown rapid development in recent years as an important technology to reduce carbon emissions, of which CO 2 geological storage is an important part. Due to the complexity of CO 2 geological storage, especially the long period of mineralization storage, intensive studies have been conducted to reveal the mechanism of mineralization storage. This review presents a comprehensive understanding of the mineralization storage mechanism and its application prospects by introducing various experimental tools to deepen the characterization of pore-scale and core-scale changes during mineralization storage and promote the application of mineralization storage in large-scale carbon storage studies through geochemical simulations and field-scale demonstrations. This review summarizes representative multiscale studies of mineralization storage in typical reservoirs. The main findings are as follows: (1) For CO 2 −water−rock reactions, in addition to the influence of the inherent inhomogeneity of reservoir rocks (properties of mineral components, etc.), the environmental conditions of the reservoir (pH, temperature, pressure, etc.) have a strong influence on the dissolution and precipitation processes during mineralized storage. (2) The mineralization sealing process is accompanied by a complex evolution of pore-permeability properties. The mineral dissolution stage causes an increase in pore space and significantly improves the fluid injection capacity, while the mineral reprecipitation process causes problems such as pore throat blockage, which often affects the safety of sealing. (3) The modeling approach, combined with laboratory work, allows for large-scale and time-scale predictions. In addition, the current implementation of successful demonstration projects is summarized to promote the use of CO 2 storage in field engineering applications. Finally, directions for future development and research are proposed.

“…Lastly, the Al-bearing fibrous zeolitelike phases occur on top of the carbonate nodules, indicating that they precipitated after the formation of the nodules. These relationships will serve to benchmark reactive transport models (e.g., Awolayo et al 91 ) that predict rates, timing, and reaction path relationships for mineral dissolution and precipitation.…”

Mitigating climate change requires transformational advances for carbon dioxide removal, including geologic carbon sequestration in reactive subsurface environments. The Wallula Basalt Carbon Storage Pilot Project demonstrated that CO 2 injected into >800 m deep Columbia River Basalt Group flow top reservoirs mineralizes on month-year timescales. Herein, we present new optical petrography, micro-computed X-ray tomography, and electron microscopy results obtained from sidewall cores collected two years after CO 2 injection. As no other anthropogenic carbonates from geologic carbon storage field studies have been recovered, this world-unique sample suite provides unparalleled insight for subsurface carbon mineralization products and paragenesis. Chemically zoned nodules with Ca/ Mn-rich cores and Fe-dominant outer rims are prominent examples of the neoformed carbonate assemblages with ankerite−siderite compositions and exotic divalent cation correlations. Paragenetic insights for the timing of aragonite, silica, and fibrous zeolites are clarified based on mineral texture and spatial relationships, along with time-resolved downhole fluid sampling. Collectively, these results clarify the mineralogy, chemistry, and paragenesis of carbon mineralization, providing insight into the ultimate fate and transport of CO 2 in reactive mafic−ultramafic reservoirs.

“…Recent work noted that accessible mineral surface area, which reflects the proportion of mineral surfaces in contact with reactive fluids, may better reflect the mineral reactive surface area in consolidated porous media. , These accessible mineral surface areas can be quantified using a multiscaling imaging approach. ,,− This surface area was able to better reflect mineral dissolution rates in a consolidated volcanogenic sandstone sample as compared with other commonly used approaches that estimate reactive surface area based on spherical grains with largely arbitrary corrections for surface roughness and reactivity …”

Mineral dissolution and precipitation reactions occur in a wide range of porous media systems, driven by deviations from an equilibrium between solid and fluid phases. Reactions occur at mineral surfaces in contact with reactive fluids or accessible mineral surface areas. These mineral surface areas can be determined using a multiscale imaging approach and have been shown to improve the simulation of mineral reaction rates in porous media compared to other estimates of reactive surface area. As reactions progress, mineral surface area evolves, and reactive transport simulations often use a simplified model assuming spherical grains to estimate mineral surface area evolution. This, however, does not depict the evolution of reactive surfaces in porous media systems with varying mineral accessibility. This work aims to quantitatively assess the evolution of accessible mineral surface area in porous media for a multimineralic system undergoing mineral dissolution reactions induced by acid exposure. Before and after the reaction, accessible mineral surface areas are determined from 2D scanning electron microscopy, and 3D X-ray computed tomography imaging of a sandstone sample. The quantified evolution of accessible surface area is compared to the calculated mineral surface area evolution using current approaches. Results show an overall increase in total surface area due to the reaction; however, individual mineral surface areas may increase or decrease. Variation is observed in mineral surface area values measured from imaging and equations used in models. The evolution of mineral surface area is largely impacted by the total surface area as well as the pore connectivity rather than porosity and volume fraction evolution.
