Oslo, December 17 - Neftegaz.RU. On 16 December Equinor and its partners started production from the Aasta Hansteen gas field in the Norwegian Sea.
17 December gas from the Aasta Hansteen field is available to the market for the first time and together with the Polarled pipeline the field opens a new region for gas export to Europe.
The company reported this on December 17, 2018.
“Aasta Hansteen is a pioneer! Located in 1 300 metres of water, this is the deepest field development on the Norwegian continental shelf (NCS), the largest spar platform in the world, and a first on the NCS. The field now coming on stream is unique,” says Anders Opedal, Equinor’s executive vice president for Technology, Projects and Drilling.
Aasta Hansteen is located 300 kilometres west of Sandnessjøen, far from other fields and in an area with harsh weather conditions.
The field has been named after another pioneer: Feminist, social commentator, painter and author Aasta Hansteen.
The field development concept consists of a floating platform with a vertical cylindrical substructure moored to the seabed (spar platform).
339 metres tall, the platform weighs 70 000 tonnes.
When the platform was towed to the field in April, it was the biggest tow on the NCS since Troll A in 1995.
The gas is produced from seven wells in three subsea templates. This is the deepest ever installation of subsea equipment on the NCS.
Both Aasta Hansteen and the 482-kilometre pipeline from the field to Nyhamna has the capacity to accommodate new discoveries.
The first one, Snefrid North, is already under development, and will come on stream towards the end of 2019.
The recoverable resources at Aasta Hansteen, including Snefrid North, are estimated at 55.6 billion standard cubic-metres (Sm3) of gas and 0.6 million Sm3 of condensate (353 million barrels of oil equivalent).
“The production from the Aasta Hansteen field will help secure long-term Norwegian gas export. With the infrastructure installed it will also be more attractive to explore around the platform and along the pipeline. This enables us to secure activity for many decades, in line with our ambitions for the NCS,” says Arne Sigve Nylund, Equinor’s executive vice president for Development and Production Norway. The exploration activity in the area around the field has already increased, and several discoveries have been made.
