The introduction of CO2 in deep formations will trigger complex geochemical/geophysical processes, which affects CO2 geological storage safety and enhanced oil/gas recovery. Previous studies mainly focused on the long-term geochemical reactions in reservoir rocks with a relatively low carbonate...

A lattice Boltzmann method (LBM) based computational REV model of geochemical reaction is proposed to describe the geochemical reactions of both solute ions transport and solid phase CaCO3 dissolution in CO2-saturated water as well as their effects on the velocity fields of fluid flows during a...
