Ormen Lange - Facts and figures
Ormen Lange is Europe’s third largest gas field, and has the world’s largest gas wells.
- Ormen Lange was discovered in 1997 and is the first true deepwater (850 – 1100 meters) project in Norway.
- The field is located 120 kilometres north west of Kristiansund in the Norwegian Sea, the reservoir approximately 3000 metres below the sea surface.
- The reservoir covers an area about 40 kilometres long and 8 to 10 kilometres wide.
- The Ormen Lange gas wells, being drilled in an area with extreme weather conditions and sub-zero water temperatures at seabed, are the world’s largest to date.
- The gas is processed onshore at Nyhamna, in Aukra municipality, and exported 1200 km to Easington, UK, through the world’s longest offshore gas pipeline, Langeled.
- At peak production, Ormen Lange will deliver close to 20 percent of the UK gas demand, and establish Norway as the world’s second largest exporter of natural gas.
- Phase 2 of the Ormen Lange project includes additional subsea templates, wells and field compression.
- Norsk Hydro was operator during the deveopment phase.
