Effects of CO2 solubility on the long-term fate of CO2 sequestered in a saline aquifer

Sequestering CO2 in aquifers is an attractive option for reducing CO2 emissions into the atmosphere. The success of CO2 sequestration during the Statoil Sleipner injection project proves that under the right conditions large volumes of CO2 can be stored in a water-bearing subsurface formation. In general, we know most of the injected CO2 will displace water and accumulate as free gas at the crest of the aquifer. © 2006 Society of Exploration Geophysicists.
