Storage of CO2 in underground geological formations has the potential of avoiding emission of huge quantities of CO2 from fossil fuels to the atmosphere, and thus possibly reducing adverse climatic effects. Beginning in 1996, 1 million tons of CO2 per year has been stored at the Statoil operated Sleipner Field in the North Sea. This is the first case of industrial scale CO2 storage in the world. Being the first case, careful depth of approximately 1 kilometer, called the "Utsira" formation, of Miocene age.
Data will be collected to model and verify the distribution of the CO2 'bubble' for three years, and demonstrate prediction methods for the destiny of the CO2 for many years into the future.
The project will also provide scientific documentation of CO2 storage as a method, which may be applied in other geographical areas and by other industries such as power generation. In concert with national resource authorities, the project will develop a first draft of a 'Best Practice Manual'
- A best-practice-manual comprising evaluation procedures on the feasibility of CO2 storage in other areas.
- The project will generate a working methodology for evaluation of subsurface CO2 storage from a technical and an environmental point of view, in order to satisfy authorithies and the general public as to the feasibility, safety, and reliability of the CO2 storage process.

No result yet, but the project partners ran a pre-project "Task Zero". It catalogued all available data about the Miocene sands, the 'Utsira' and its equivalents around the North sea.
This project is structured in phases : each covering the work, budget and schedule of a set of defined tasks. The phasing is necessary for funding reasons. The tasks will be executed partly in parallel, partly in sequence. Each task is assigned to one institute with defined work content, budget and schedule. Other industries may support the task responsible. Because of the iterative nature of modeling the different areas, some tasks are time staggered.
Main work areas :
1. Geological modeling : collecting data from the region and build a geological model of 'Utsira' and caprock.
2. Reservoir simulation : Based on fluid and rock properties model the spread of CO2 "bubble" in 'Utsira' formation.
3. Geochemical studies : Laboratory experiments will establish base for later geochemical/flow model development.
4. Monitoring well : Evaluate needs and define specifications for a possible future monitoring well.
5. Geophysical monitoring : Seismic and gravimetric time-lapse data collection will check viability of these methods for a CO2-water-system and give reference for evaluation of available geological and reservoir models.
6. Best Practice Manual : In addition to reporting results, a first draft of a 'Best Practice Manual' will be made; It will be made in close co-ordination with national resource authorithies in NO, DK, NL, FR(?) and UK.
