CO2 Storage - SUCCESS-CEER

Subsurface storage of CO2 may become a strategy for reducing emissions of climate gases to the atmosphere from large point sources.

The Research Council of Norway awarded 8 research centres for environmental friendly energy research (CEER) for 8 years in 2009. We contribute to one of these centres Subsurface CO2 storage – Critical Elements and Superior Strategy (SUCCESS).

CO2 is a natural gas that is found everywhere. 
It is in the air we breathe in and out, and can be found below ground either isolated or together with oil, gas and coal. Despite the natural presence of CO2 below ground, there is still not enough known about how CO2 will behave in high concentrations at depths of several hundred metres to tell us whether it is both possible and safe – we must be sure it will be safe for a long time, certainly for more than 1000 years. What reactions will occur? What kinds of minerals will be dissolved, and what kind will be formed?

Today CO2 is stored in a few sites around the world in formations near by oil and gas reservoirs.
Two of these locations are on the Norwegian shelf, namely Sleipner and Snøhvit. Yes, it’s true to say that as a nation, Norway is also far advanced on this front. There are several similarities between CO2 subsurfacce storages and petroleum reservoirs. Such a reservoir should be porous and there must be communication between the individual pores so that the pore space can be filled. In addition a reservoir must be sealed by an impenetrable cap rock or fault that prevents the gas or oil from escaping. Are there potential CO2 storage sites in the vicinity of large sources of CO2 emissions?

About the group

We have acquired considerable experience over the years with the geochemical reactions that occur between minerals, water and different gases, as well as through our petroleum related research.

About SUCCES

Christian Michelsen Research (CMR) is the host institution for the centre, and partner institutions are Institute for Energy Technology (IFE), Norwegian Institute for Water Research (NIVA), Norwegian Geotechnical Institute (NGI), Uni Research, the University of Bergen (UiB), the University of Oslo (UiO) and the University Centre in Svalbard (UNIS). Our Department hosts the Oslo node of the Research Centre for Environment Friendly Energy Research, SUCCESS - CEER.

The SUCCESS centre addresses several important areas for CO2 storage in the subsurface. Our researchers contribute in areas as storage characterization, geochemical and geomechanical response, fluid flow and reservoir modeling as well as the understanding of sealing properties.
