Snøhvit is a gas and condensate field northwest of Hammerfest in Northern Norway. It was the first development in the southern Barents Sea and was the first major development on the Norwegian continental shelf with no surface installations.
The well stream is transported in a 143-kilometre pipeline for processing to liquid natural gas (LNG) at the Melkøya onshore facility near Hammerfest. Carbon dioxide (CO2) is separated and returned to the field by pipeline for injection into the aquifer (CCS), while LNG, liquid petroleum gas (LPG) and condensates are shipped to market.
A total of 16 wells have been drilled on the Snøhvit field, 14 producers and two wells for reinjecting carbon dioxide (CO2). The plant on Melkøya captures CO2 from the well stream, before returning it to the field far below the seabed. 700,000 tonnes of CO2 are captured and stored each year, equivalent to the emissions from 400,000 cars.
