Description

• The Dvalin gas field was previously known as Zidane, consists of two separate structures: Dvalin East and Dvalin West. The water depth is 400 metres.
• The field is located in Production Licence (PL) 435, approximately 15 kilometres northwest of the Heidrun field and 35 kilometres south of the Skarv field in the Norwegian Sea.
• The development concept is a subsea template with four gas producers tied back to the Heidrun platform.
• Gas from the field will be transported via Heidrun through the Polarled Gas Pipeline to the Nyhamna Gas Plant
• Production was delayed when the level of mercury in the gas exceeded what was expected.

Dvalin North

• The Dvalin North gas field is located around 200 km off the coast of Northern Norway, west of Sandnessjøen at a water depth of 420 metres. It is estimated to contain around 84 million barrels of oil equivalent
• The development concept includes drilling three producing wells from a single subsea template, and pipeline connections to the existing Dvalin field located 10km to the south

Contractors

• **Technip**: EPCI contract for the subsea development
• **Aker Solutions:** A production system encompassing a manifold, four subsea trees and a 15-kilometer long umbilical

History

• 2010 - Dvalin Gas Field discovered
• 2012 - A second gas-bearing reservoir was discovered
• 2016 - Contracts awarded for the development
• 2019 - First production wells drilled
• 2021 - Project delayed due to high levels of mercury
• 2022 - PDO submitted for Dvalin North
• 2023 - First gas from the Dvalin field

Geology

• Dvalin consists of two separate structures, Dvalin East and Dvalin West. Both discoveries contain gas in Middle Jurassic sandstones of the Garn and Ile Formations.
