Fluid-CO2 injection impact in a geothermal reservoir: Evaluation with 3-D reactive transport modeling

Review on Multiscale CO2 Mineralization and Geological Storage: Mechanisms, Characterization, Modeling, Applications and Perspectives

“…D’Aniello et al simulated the flow behavior of gaseous CO 2 in stratified basalts, and the predicted profile of gaseous CO 2 saturation at 3 days is shown in Figure a. At the same time, predictive three-dimensional reaction transport modeling, as shown in Figure b, can achieve an accurate prediction of changes in the mineral content, pH, and CO 2 mass fraction . More recent reaction-transport simulation studies are closer to the actual situation, where SO 2 was co-injected as an impurity in CO 2 flue gas.…”

“…shown in Figure 14b, can achieve an accurate prediction of changes in the mineral content, pH, and CO 2 mass fraction. 175 More recent reaction-transport simulation studies are closer to the actual situation, 176 where SO 2 was co-injected as an impurity in CO 2 flue gas. The development of the CO 2 plume was observed from the perspective of gas saturation, 177 as shown in Figure 14c,e, to explore the geochemical influence on reservoir rocks.…”

Utilizations of reaction exothermic heat to compensate the cost of the permanent CO2 sequestration through the geological mineral CO2 carbonation

“…This is evidenced by a project in Iceland demonstrating profitable potentials of the mineral carbonation process to co-capture and store other acid gases (e.g., H2S and SO2). Even more, another geological rock formation, basalt, shows more advantages in the mineral carbonation, which exists in both igneous reservoirs and geothermal fields 37,38 . Its economics and the implementation approach will be further discussed in details in our subsequent paper.…”

A review of carbon mineralization mechanism during geological CO2 storage

“…The authors also analyzed the nucleation locations for each mineral, and insisted that calcite preferentially precipitated on pyroxene, magnesite was more uniformly distributed, and siderite preferentially precipitated on olivine. Erol et al [ 57 ] constructed a 3-D reactive transport model using TOUGHREACT for 3 types of metamorphic formations, i.e., schist, schist-marble, and marble. Despite the precipitation of ankerite, the results showed that the carbon mineralization was limited because of the high initial mass fraction of CO 3 2− in the schist and marble formations.…”
