Wintershall Dea has started production from Dvalin gas field in the Norwegian Sea, providing new gas volumes to the European market.
The field, in the Haltenbanken area some 260 km north of Kristiansund, has been shut-in since late 2020 after measurements of high levels of mercury in the well stream. Since then, mercury removal units have been installed at the onshore processing plants at Nyhamna and Tjeldbergodden in Norway.
Dvalin gas field was developed through a single subsea template with four production wells connected to the nearby Heidrun platform. The field joins Maria, Nova, and Vega as Wintershall’s fourth operated subsea field in Norway. It is also the tie in point for Wintershall-operated Dvalin North subsea gas development, which was approved by the Norwegian government in 2023 and is currently under development (OGJ Online, Jan. 10, 2023).
Dvalin field has an estimated lifetime until 2038 including Dvalin North field. Dvalin holds expected recoverable gross reserves of at 113 MMboe of which the majority will be gas. Wintershall Dea is operator of Dvalin field with 55% interest. Partners are Petoro (35%) and Sval Energi (10%).
