Wintershall Dea’s operated Dvalin gas field in the Norwegian Sea has resumed production, the company announced on Aug. 23.
The field had been shut-in since 2020 due to high levels of mercury in the production stream. Mercury removal units have now been installed at the onshore processing facilities at Nyhamna and Tjeldbergodden in Norway.
“The team has worked hard to overcome technical challenges in the field,” Michael Zechner, Wintershall Dea Norge managing director, said in a news release.
Dvalin produces to the nearby Heidrun platform about 15 km away. It features a single subsea template with four production wells and targets recoverable reserves of 113 MMboe, with the majority gas.
The Dvalin Field, in 340 m to 400 m water depth, is expected to produce through 2038 with the addition of production from the Dvalin North Field, which is currently being developed. The subsea tieback development plan for Dvalin North was approved in June.
