Abstract
The Kyoto Accords have been signed by 140 nations in order to significantly
reduce carbon dioxide emissions into the atmosphere in the medium to long term.
In order to achieve this goal without drastic reductions in fossil fuel usage, carbon
dioxide must be removed from the atmosphere and stored in acceptable reservoirs.
Research has been undertaken to develop economical new technologies for the
transfer and storage of carbon dioxide in saline aquifers. In order to maximize the
storage rate, the aquifer is first hydraulically fractured in a conventionalwell stimulation
treatment with a slurry containing solid proppant. Well fracturing would
increase the injection volume flowrate greatly. In addition, there are several ancillary
benefits including extension of the reservoir early storage volume by moving
the carbon dioxide further from the well. This extended reach would mitigate the
problems with the buoyant plume and increase the surface area between the carbon
dioxide and the formation facilitating absorption. A life-cycle cost estimate
has been performed showing the benefits of this approach compared to injection
without fracturing.
Keywords: carbon dioxide sequestration, reduction of green house gases, hydraulic
fracturing.
