Facts:

Main developer: Statoil

Since 1996, Statoil has captured one million tonnes per annum of carbon dioxide from natural gas production at Sleipner West and stored it in an aquifer more than 800 metres below the seabed (Utsira formation). On Sleipner, CO2 is captured using a conventional amine process and stored in the geological layers. From 2014, capture and injection capacity will be expanded from 1 Mtpa to 1.1-1.2 Mtpa.

Sleipner is the second largest gas producer in the North Sea (after Troll) and delivers gas to the continent and the UK. The Sleipner project is world famous because of its offshore CO2 capture.

Sleipner produces 300 000 barrels oil equivalents and 36 million Sm3 of natural gas every 24th hour. At the end of 2008 almost 11 million tonnes of CO2 had been stored.

Storage:

Statoil has been capturing around one million tonnes of CO2 offshore at the Sleipner platform since 1996. The gas is stored more than 800metres below the seabed in an aquifer. Statoil captures about 2600 tonnes of CO2 every day from the gas produced on Sleipner. The way the CO2 spreads underground at this storage site has been monitored by various research projects, which are funded in part by the European Union. The Utsira reservoir is continuously monitored using seismology, and comprehensive models have been developed for calculating how the CO2 moves in the reservoir.
