2017/4/11
Hydrogen and oxygen isotopic analysis using an off-axis integrated-cavity output spectroscopy (OA-ICOS) was carefully
checked for long-term stabilities, dependence on the injected water volume, inter...
2-D numerical modeling of CO2-water-caprock interactions at a potential CO2 storage site in Turkey
CO2 storage caprock integrity CO2-water-rock interactions reactive transport modeling
2017/4/11
Caprock integrity is an important subject, as it is closely related to the leakage of injected CO2 into geological formations.
Thus, it is necessary to evaluate how injected CO2 affects caprocks duri...
