[CEST2019_00721] Numerical simulation of CO2-brine-rock interactions on CO2 sequestration in Shihezi Formation of Ordos Basin in China

Session: 29, Room:
Geochemical reactions play an important role in CO2 geological storage environments. CO2-brine-rock interactions will be enhanced in low pH environment, because of acidity in reservoir being strengthened due to CO2 dissolution. TOUGHREACT is used conduct kinetic batch modeling and reactive transport modeling in Shihezi formation in Ordos basin, where the first CCS project is carried out in China. Simulations are based on the core data, which are focused on effects of CO2 for pH, gas saturation, geochemical interactions, porosity and permeability in formation.
