Project Profile
Value: US$8,000 million
Location: Norwegian Continental Shelf, 33/12
Start-up Month: October
Start-up Year: 2007
Water Depth: 1,000m
Upstream Gas Reserves: 315 billion cubit metres of natural gas
The Ormen Lange is located in the Norwegian Sea, approximately 140km west of Kristiansund, Norway. The blocks include 6305/4, 6305/5, 6305/6 and 6305/8. The Ormen Lange is the third-largest gas discovery on the Norwegian shelf. The discovery well 6305/5-1 was drilled in 1997. Production from the field began in 2007. The field produces for an onshore gas processing plant at Nyhamna in Aukra. The main gas reserves lie in a reservoir in the Vale formation. Drilling has confirmed the original estimated resources of 315 billion square metres of natural gas. Ormen Lange lies in a depth of 800-1,200m. The above operators are all involved of the planned Phase II development, which is reaching the FEED stage. Ormen Lange lies in a depth of 800-1,200m.
The first phase of field development consisted of two subsea templates, pipelines to onshore and an onshore gas processing plant. Each subsea template has slots for eight wells. The wells were tied to the templates through subsea manifolds. The gas, condensate and water are transported from subsea templates via two 30in pipelines to an onshore process terminal at Nyhamna. The pipelines were installed by Saipem. The Phase II development has three options which are being considered. This includes a possible platform based compression solution. The tension-leg platform would be located in water depths range between 800 and 1,100 metres. Two subsea compression options are being considered: a four-train system to come on stream in late 2017 or a combination of a two-train solution from 2016 to be supplemented with onshore compression two years later.
