Modeling and assessment of CO2 geological storage in the Eastern Deccan Basalt of India

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

“…To roughly estimate the change in permeability due to a change in porosity, it is assumed that the Carman–Kozeny equation can be used to describe the porosity–permeability relationship for reservoirs such as basalt, which is derived under the assumption that porous media are homogeneous spherical particles and the Hagen–Poiseuille equation describes the fluid flow through the pore space. The formation permeability can be written as K = D normalp 2 72 τ φ 3 false( 1 − φ false) 2 where τ is the tortuosity of the porous medium and D p is the particle diameter. The permeability K can be written as a function of porosity φ as ,, K = K init false( 1 − φ init false) 2 φ init 3 φ 3 false( 1 − φ false) 2 where K init is the initial permeability and φ init is the initial porosity.…”

“…Liu et al performed a field-scale assessment of the CO 2 mineralization storage potential of the East Deccan basaltic formation in India based on geological, hydrological, and geochemical parameters and developed a two-dimensional homogeneous field model of 200 m by 120 m, as shown in Figure a. Postma et al used VIRTra (a vertically integrated reactive transport model specifically developed for field-scale modeling of CO 2 storage in reactive rocks) to conduct extensive numerical experiments to explore the behavior of geochemical reactions occurring in the water–CO 2 –basalt system when CO 2 is sequestered in basaltic reservoirs.…”

The dissolution rates of naturally altered basalts at pH 3 and 120 °C: Implications for the in-situ mineralization of CO2 injected into the subsurface

“…This process was upscaled to capture and store the bulk of the carbon emissions at the Hellisheiði power plant by its injection into altered basalts at temperatures of ~250 o C (Gunnarsson et al, 2018;Clark et al, 2020). Plans are currently underway to adopt this approach at other sites (Galeczka et al, 2022), and the subsurface mineralization of basalts have been proposed in other regions including the Deccan traps of India (Shrivastava et al, 2016;Liu et al, 2022) and the East African Rift basalts (Okoko and Olaka, 2021). Since mafic rocks, such as basalt, are widely distributed in the Earth's crust and ocean floor, the potential storage capacity of subsurface mineralization is vast.…”
