Norway – Edvard Grieg

Edvard Grieg reservoir performance continues to exceed expectations leading to an extension of plateau production until mid-2020.

Edvard Grieg first oil November 2015

The majority of Lundin Petroleum’s current production comes from its key operated Edvard Grieg asset in PL338 on the Utsira High in the Norwegian North Sea. The field contributed close to 80 percent of total production in 2018 at a cash operating cost of less than USD 4 per barrel. Increased facilities capacity, high production efficiency and strong reservoir performance are the key drivers behind this excellent performance.

The field was discovered in 2007 with Lundin Norway’s first exploration well and production started in late 2015. The field development consists of a steel jacket platform resting on the seabed with topsides including a process facility module, utility module and living quarters. Edvard Grieg is designed as a field centre and receives oil and gas from neighbouring fields and will have the capacity for future developments in the area. Oil is transported via the Grane pipeline to the Sture terminal in Øygarden in Hordaland, while gas is transported via a separate pipeline system to St. Fergus in Scotland.

The development drilling programme on Edvard Grieg was successfully completed in 2018 with overall reservoir results exceeding the pre-drill expectations. Combined with a strong reservoir performance, that has seen no material water production to date, these positive results have led to a 52 percent increase of the best estimate gross ultimate recovery for the Edvard Grieg field since PDO. This positive upgrade has led to the field production plateau being extended from PDO by over two years to mid-2020.

Three further development projects have been sanctioned in the Greater Edvard Grieg Area. An infill drilling programme on Edvard Grieg will commence in 2020 and the Solveig and Rolvsnes projects are scheduled for first oil in 2021. Both Solveig and Rolvsnes will be developed as tie-backs to the Edvard Grieg platform and along with the infill drilling programme, will further extend the production plateau.

The resource upside at Edvard Grieg and the additional resource potential in the area are incremental to Lundin Petroleum’s long-term production guidance and have the potential to keep the Edvard Grieg facilities full for many years, maintaining the current operating cost for the field of below USD 4 per barrel.

Lundin Norway is the operator of PL338 with a 65 percent working interest. The partners are OMV Norge with 20 percent and Wintershall Norge with 15 percent.
