Abstract

Carbon dioxide (CO2) is one of the main greenhouse gases that its high concentration in the atmosphere has caused the global warming issue. Sequestering CO₂ in a suitable geological subsurface formation can be a feasible method to reduce the CO₂ concentration in the atmosphere. CO₂ sequestration in saline aquifers can store a significant volume of CO₂ underground for thousand years. However, injecting CO₂ into such formations does not guarantee a safe storage because CO₂ could leak back to surface or contaminate the formation water. Hence, a proper evaluation of the sequestration site is required. In this study, a case study regarding CO₂ sequestration in saline aquifers was conducted using CMG-GEM compositional simulator to study the effects of aquifer permeability, injection pressure and well trajectory on CO₂ trapping mechanisms during sequestration process. A field-scale model with one injector well in which CO₂ was injected into the aquifer for ten years and simulated for hundred years was studied. The results showed that, CO₂ solubility trapping is the dominant mechanism with less risk of leakage when the aquifer has a good vertical permeability and the injection pressure is not high regardless of the well trajectory.
