 | Stabilizing Atmospheric CO2 Concentration: Can Geologic Storage Help? |
 by Lynn Orr
One option for reducing emissions of CO2 to the
atmosphere as a result of combustion of fossil fuels is to capture CO2
and inject it into porous subsurface geologic formations. High pressure CO2 has been used
for the last three decades as an agent for enhanced oil recovery, and hence
considerable experience in the technical issues associated with predicting the
movement of CO2 in the subsurface has been accumulated. Significant additional quantities of CO2
could be stored in depleted oil and gas reservoirs if CO2 were
available at low cost. These formations
are appealing as storage sites because the subsurface is known to have a trap
and seal that contains the buoyant oil or gas.
