Sub-seabed CO2 Storage

With this selection of study sites, each at a different operative stage, ECO2 will cover the major geological settings to be used for the storage of CO2 including depleted oil and gas reservoirs (B3 field site, 80 m water depth), saline aquifers located at the continental shelf (Sleipner, 90 m water depth), and the upper continental slope (Snøhvit, 330 m water depth, see section B1.3 for more detailed information on study areas).
In response to the call, we have developed five key objectives for ECO2.


  • To investigate the likelihood of leakage from sub-seabed storage sites
  • To study the potential effects of leakage on benthic organisms and marine ecosystems
  • To assess the risks of sub-seabed carbon dioxide storage (based on objectives 1 and 2)
  • To develop a comprehensive monitoring strategy using cutting-edge monitoring techniques
  • To define guidelines for the best environmental practices in implementation and management of sub-seabed storage sites (based on objectives 1 to 4)
