Equinor and its partners have announced the start of production from the Aasta Hansteen gas field in the Norwegian Sea.
The deep-water gas development is located in the northern part of the Norwegian Sea, 300 kilometers from the mainland of Norway and in water depths of 1,300 meters.
Equinor is the operator of Aasta Hansteen with a 51 per cent stake and Austria's OMV has a 15 per cent interest in the field. The other partners are Germany's Wintershall and ConocoPhillips Skandinavia with a 24 per cent and a 10 per cent share, respectively.
“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.
The total gross estimated recoverable reserves, including Snefrid North discovery, which has been included in the development, are approximately 324 million boe and 4.1 million boe of condensate.
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.
“Aasta Hansteen has been a complex and challenging development project, requiring us to take new technological steps together with our partners Wintershall, OMV and ConocoPhillips as well as the suppliers,” says Opedal.
Gas from Aasta Hansteen will be transported via pipeline to Norway and then further exported to the European market. The condensate will be loaded to shuttle tankers and transported to the market.
The total capital investment in the Aasta Hansteen project is approximately EUR 4 billion.
