Norway Big player on the shelf
More than 45 years in the country, over 100 licences: Wintershall Dea is one of the leading gas and oil companies in Norway, one of Europe's most important energy suppliers.
The Norwegian TV series “Lykkeland” looks at the beginnings of Norway's oil industry.
Norway is Europe’s most important supplier of natural gas and oil besides Russia. Wintershall Dea is now one of the leading gas and oil companies on the Norwegian Continental Shelf, having operated there for more than 45 years. The company has more than 100 licences on the shelf and is operator in around a third of them, for example the producing fields Brage and Vega. The portfolio is being expanded further with smart technical solutions. For instance, the company is attracting attention with projects such as Dvalin or Nova. These fields are being developed by means of a subsea tieback, with production facilities on the seabed connected to existing platforms.
The company’s exploration and production concessions are located in all regions on the Norwegian Continental Shelf: in the North Sea, Norwegian Sea and the Barents Sea. Nova and Brage are located around 125 kilometres west of the city of Bergen. Maria lies further north, roughly at the level of Trondheim, and Dvalin lies even further north.

Dvalin
The Dvalin field was not considered worthwhile in the 1980s. It was not until the new millennium that a consortium led by Wintershall Dea (then DEA Deutsche Erdoel AG) successfully explored for natural gas. In 2010 and 2012, exploration wells struck two gas-bearing horizons with thicknesses of 150 and 140 metres respectively. To enable production from the field, four production wells are connected to the existing Heidrun platform, via a subsea template installed on the seabed.
The mobile West Mira drilling platform is to drill a total of six wells in the Nova field.
Nova – advantages thanks to technology
The oil and gas reservoir was called Skarfjell when it was discovered in 2012. It was later given the name Nova. Besides Maria and Dvalin, the field is a further self-operated discovery in Norway that Wintershall Dea intends to develop and put on stream. The company is yet again demonstrating its expertise for subsea technology in this project: The reservoir is connected to the nearby Gjøa field via a subsea tieback. That saves resources and money.
The Brage field lies to the northwest of Bergen, Norway's second-largest city.
Brage – the first production platform of our own
The Brage platform has been producing crude oil from the field of the same name since 1993. Wintershall Dea (then Wintershall) became the operator in 2013. The new wells drilled since then are some of the most efficient to date and are developing new parts of the field. Wintershall Dea Norge is currently conducting a two-year feasibility study to investigate using injected CO2 for enhanced oil recovery (EOR) on the field. It assesses how a mature field like Brage can be used for permanent CO2 storage after the production period is completed. In the study, it is assumed that CO2 will be transported by ship for direct injection into the reservoir.
The Njord A platform which produced oil and gas from 1997 until 2016.
Njord – new start for a greater yield
Production at the Njord field began in 1997 and was interrupted in 2016 for modernization work on the floating platform being used. The aim is to significantly expand output from the field, in which Equinor operates and in which Wintershall Dea has a 50 per cent stake. Ten new production wells are envisaged as part of the Njord Future project.
