Equinor and its partners have begun production from the Aasta Hansteen gas field in the Norwegian Sea, the company said in a news release.
“Located in 1,300 meters [4,265 ft] 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,” Anders Opedal, Equinor’s executive vice president for technology, projects and drilling, said in the news release.
The field development concept consists of a floating 339-m (1,112-ft) tall, 70,000-tonne platform with a vertical cylindrical substructure moored to the seabed, the company said. Gas is produced from seven wells in three subsea templates.
“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,” Opedal said.
Equinor said Aasta Hansteen and the 482-km (300-mile) 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 onstream toward year-end 2019.
Recoverable resources at Aasta Hansteen, including Snefrid North, are estimated at 55.6 billion standard cubic meters of gas and 0.6 million standard cubic meters of condensate, the company said.
