The Dvalin field consists of two separate structures. Dvalin East (Zidane 1) was proven in 2010 by 6507/7-14 S well and is located 15 km northwest of the Heidrun field. Dvalin West (Zidane 2) was proven in 2012 by 6507/7-15 S well and is located 3.5 km west of Dvalin East.
The Dvalin gas field located in PL435 in the Norwegian Sea is operated by Wintershall DEA (55%), with Petoro (35%) and Edison (10%) as partners.
Both Dvalin East and Dvalin West contain gas in Middle Jurassic sandstone in the Ile and Garn Formations. The reservoirs lie at a depth of 4,500 m and have high pressure and high temperature (HPHT). The homogeneous shallow marine Garn sandstone has good reservoir quality, while the more heterogeneous and fine-grained Ile sandstone has less favourable reservoir properties.
According to Wintershall DEA the field has estimated reserves of 113.3 MMboe.
Dvalin is being developed as a subsea field tied back to to the Equinor operated Heidrun platform. The four wells will be drilled to a depth of around 4,500 m.
