Snøhvit was the first development in the southern Barents Sea. Without surface installations, large volumes of natural gas are brought ashore for liquefaction at the world’s northernmost and Europe’s first liquefied natural gas (LNG) facility.

Snøhvit was the first major development on the Norwegian continental shelf with no surface installations.

The subsea installations are designed to be overtrawlable, preventing damage to installations and fishing gear in the event of contact.

No platform or production vessel in the Barents Sea indicates where the field is located. Instead, the production facilities stand on the seabed, in between 250 and 345 metres of water. About 20 wells will be drilled here, producing the gas in the Snøhvit, Askeladd and Albatross reservoirs. The gas is transported ashore through a 143-kilometre pipeline. 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, storing it on the seabed. 700 000 tonnes of CO2 are captured and stored each year, equivalent to the emissions from 400 000 cars.

The Snøhvit production has reached the plateau phase. Since production started, several production wells have been drilled in various structures. Efforts are underway evaluating future compression concepts, as well as measures to reduce the CO2 emissions from the onshore facilities on Melkøya. The Cold Return project (bringing the LNG plant back online) is scheduled to be completed in the spring of 2022.

Gas from the Snøhvit and Albatross reservoirs came on stream in 2007. Askeladd will be put on stream in 2022.
