Geologic sequestration is the underground storage of CO2 in existing geologic formations. The following six types of repositories provide the best oppertunites for permenant sequestration: 1) oil reserviors 2) natural gas deposits 3) unminealbe coal seams 4) deep saline formations 5) shale rich in oil or gas 6) basalt formations.
All sequestration techniques involve extensive monitoring, mitigation and verification (MMV) and continuous risk assesment of the site. Effective application of proper MMV procedures will ensure the saftey of carbon sequestration techniques with regards to human and environmental health.
