The Nova field, which came on stream in the summer of 2022, is developed with two subsea templates tied back to the existing Gjøa platform. The use of existing infrastructure enables efficient extraction of the resources in the reservoir at 2,570 metres below sea level. It also unlocks future tie-in opportunities and extends the economic lifetime of the Gjøa infrastructure in which Wintershall Dea has a 28% share . Nova is sustainably operated with hydro power from shore through Gjøa.

Nova’s sustainable development solution creates a win-win for Wintershall Dea, the Nova partnership consisting of Sval Energi and Pandion Energy Norge, the Gjøa licence, and the Norwegian society.

About Nova

Nova is located about 120 kilometres northwest of Bergen and 17 kilometres southwest of Gjøa. The water depth is roughly 370 metres. The field consists of two subsea templates, one with three oil producers and one with three water injectors, tied back to Neptune Energy’s Gjøa platform. The host platform provides gas lift and water injection to the field and receives the Nova hydrocarbons

The expected recoverable gross reserves from the field are estimated at 90 million barrels of oil equivalent (boe), of which the majority is oil.

Oil from Nova is transported via Gjøa through the Troll Oil Pipeline II to Mongstad in Norway, associated gas is exported via the Far North Liquids and Associated Gas System (FLAGS) pipeline to St Fergus in the UK, supplying the European energy market.

Nova uses existing infrastructure to deliver maximum value.

Developing a core area

Nova is located in the Q35 area of the North Sea, which is a core region for Wintershall Dea. As a satellite field of the Gjøa platform, Nova twins with Wintershall Dea’s Vega field which also ties back to the same facility. Alongside a series of promising discoveries and exploration licenses, the region promises to be a continuing growth area.
