Numerical simulation of CO2 disposal by mineral trapping in deep aquifers
TLDR
In this article, the authors analyzed the impact of CO2 immobilization through carbonate mineral precipitation in aquifers, and found that the amount of CO 2 that may be sequestered by precipitation of secondary carbonates is comparable with and can be larger than the effect of dissolution in pore waters.About:

TOUGHREACT-A simulation program for non-isothermal multiphase reactive geochemical transport in variably saturated geologic media: Applications to geothermal injectivity and CO2 geological sequestration
TL;DR: This work examines ways in which the chemical composition of reinjected waters can be modified to improve reservoir performance by maintaining or even enhancing injectivity, and uses recent European studies as a starting point to explore chemically induced effects of fluid circulation in the geothermal systems.

Permanent storage of carbon dioxide in geological reservoirs by mineral carbonation
Jürg M. Matter,Peter B. Kelemen +1 more
TL;DR: In this paper, the authors show that the rate of carbonate mineral formation is much higher in host rocks that are rich in magnesium- and calcium-bearing minerals, such as basalts and magnesium-rich mantle rocks that have been emplaced on the continents.
