| Summary: | Carbon Capture and Storage (CCS) is the capture of carbon dioxide (CO?) from large source points, such as power plants, and storing it in geological formation. It is a potential means of reducing CO? concentration in the atmosphere to mitigate global warming and ocean acidification. Geological formations are considered to be the most promising storage sites for carbon dioxide. Deep saline aquifers have the most storage capacity compared to other geological sites. ? After CO? is injected into an aquifer, a fraction of it, that can be large, is immobilized in the form of residual phase. Residual entrapment is an important component in successful storage of CO? in saline aquifers. Trapped CO? is eventually dissolved into the brine. Estimation of the fraction of the injected CO? that is trapped depends on CO? saturation profiles and saturation history. In the simulation of CO? injection into saline aquifers, conventional relative permeabilities functions are commonly used and it is assumed that viscous coupling ... |
