Production drilling begins on Norway’s Dvalin field
Wintershall Dea has begun drilling four production wells on the Dvalin gas field in the Norwegian Sea, getting ready for the field to come onstream in 2020. Dvalin is to be developed as a four-well subsea tie-back to the Equinor-operated Heidrun field. Drilling of the production wells from the Transocean Arctic rig (pictured) is expected to last approximately one year.
August 2019, a 3,500 tonne processing module was completed and lifted on to the nearby Heidrun platform in preparation for receiving gas from the Dvalin field. The gas will be sent to the Polarled gas transportation system via a 7.5-kilometre pipeline, before being further processed to dry gas at the Nyhamna onshore gas terminal. Finally, the gas will be transported via Gassled to the market.
Wintershall Dea is operator of the Dvalin development, holding a 55% interest, partnered by Petoro (35%) and Edison (10%). Estimated reserves are put at 113.3mn boe.
