Current and Future Developments

• Solsort West Lobe Development:
  • INEOS Oil & Gas Denmark is developing the Solsort West Lobe, which involves drilling two wells from the South Arne North platform. The produced fluids will be commingled with South Arne production and processed at the South Arne main platform.
• Hejre to South Arne Development Project:
  • INEOS E&P A/S plans to develop the Hejre field by tying it back to the South Arne platform. This project includes drilling, construction, and installation activities, as well as environmental impact assessments.

Environmental and Regulatory Aspects

• The development projects, including the Solsort West Lobe and Hejre tie-back, are subject to comprehensive environmental impact assessments (EIA) in compliance with Danish and EU regulations. These assessments include evaluations of potential impacts on Natura 2000 sites, air emissions, waste, and noise.

Contribution to National Output

• The South Arne field currently accounts for approximately 9% of Denmark’s daily oil and gas output.
