Although it is recognized that deep aquifers offer the potential for very large storage capacities for CO2 sequestration, it is not clear what the best method is to fill these aquifers with large volumes of CO2 in a relatively short period of time within localized injection areas. The typical benchmark for the rate of CO2 injection is 1 Mt/year when studying storage performance. This rate is very low when compared to the scale needed for storage technology to play a significant role in managing global emissions. In this report we study the feasibility of injecting large volumes of CO2 into the Nisku aquifer, which is located in the Wabamun Lake area in Alberta, Canada [1]. In this area, large CO2 emitters include four coal-fired power plants with emissions that range between 3 and 6 Mt/year each, which together emit ~ 20 Mt/y or ~ 1 Gt over 50 years. This number, 1 Gt, is considered the target capacity for WASP. The Nisku aquifer is believed to be a suitable choice for future sequestration projects.
