Edvard Grieg Area

Edvard Grieg reservoir and facilities performance continues to exceed expectations

An important part of Lundin Energy’s production comes from its key operated Edvard Grieg asset in PL338 on the Utsira High located in the central North Sea. The field is a key production contributor at a low cash operating cost of around 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 Energy 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.

Development drilling on Edvard Grieg has been successful with overall results exceeding the pre-drill expectations with respect to reservoir quality and exposure. The strong reservoir performance, 4D seismic and planned infill drilling in 2021 have resulted in a significant plateau extension and reserves increase. Along with the two subsea tie-back projects Solveig and Rolvsnes, the area has seen a 94% increase in best estimate gross ultimate recovery compared to the Edvard Grieg Plan for Development and Operation (PDO).

3 further development projects

In the Greater Edvard Grieg Area three further development projects have been sanctioned; an infill drilling programme on Edvard Grieg will commence in 2020 and the Solveig and Rolvsnes projects are scheduled for first oil in 2021 and 2022 respectively. 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.

Electrification of Edvard Grieg

In October 2019, the plan for electrification of the Edvard Grieg platform was announced, which is being developed together with the Johan Sverdrup Phase 2 project as part of the Utsira High Area power grid. The project will become operational in 2022 and lead to a significant reduction of CO2 emissions from the field, taking the CO2 emissions for the area to below 1 kg per barrel. Additionally, the project will reduce operating costs, reduce carbon taxes and increase operating efficiency; which will be partially offset by electricity power purchases from the grid, generated mostly from renewable sources. Overall the project will enhance the economic return from the Edvard Grieg Area, while at the same time significantly reducing CO2 emissions.

CarbonClear certification for Edvard Grieg

Edvard Grieg is the first field in the world to be awarded the CarbonClear certification, the new independent upstream carbon intensity certification for oil and gas producers. With carbon emissions of 3.8 Kg CO2 per barrel, which is nearly a fifth of the industry average, we further demonstrate our target of becoming carbon neutral across our operations by 2030.

Aker Solutions Wins Electrification Work for Lundin Energy Norway

Aker Solutions has signed an engineering, procurement, construction and integration (EPCI) contract for the integration of a high-voltage electrical boiler package as part of the electrification of Lundin Energy Norway's Edvard Grieg platform. Photo: Lundin Energy Norway

The electrical boilers will replace the gas turbines which generates heat on the platform today, making Edvard Grieg a fully electrified platform. All heating and power needed for the platform will come from electrical power from shore by 2022. This accounts for an annual emission reduction of around 200,000 metric tons of CO2.

"We look forward to working with Lundin to fully electrify the Edvard Grieg platform," said Linda Litlekalsøy Aase, executive vice president, brownfield projects, at Aker Solutions.

The work starts immediately and will involve more than 50 employees at Aker Solutions' facilities in Fornebu, Stavanger and Egersund, Norway.

Aker Solutions has previously provided engineering work for the Edvard Grieg development.

The Edvard Grieg field is located in the Utsira High area of the North Sea, about 180 kilometers west of Stavanger, Norway.

Edvard Grieg

Image

Edvard Grieg was proven in 2007 with Lundin Energy Norway's very first exploration well.

The Edvard Grieg platform is our first own operated production platform. Production commenced in November 2015.

Lundin Energy Norway is the operator with an ownership interest of 65 per cent. Wintershall Norge and OMV Norge are the other owners.

Some facts:
The Edvard Grieg reservoir is situated at a depth of approx. 1,900 metres, and consists of alluvial, eolian and shallow marine conglomerates and sandstones from the Triassic to Lower Cretaceous ages. The northernmost appraisal well (16/1-15, Tellus) encountered a reservoir consisting of porous, fractured bedrock underlying a thin sandstone layer from the Lower Cretaceous Age.

The field contains under-saturated oil without a gas cap. The Edvard Grieg field consists of a platform resting on the seabed (steel jacket), with a full process facility, dry wellheads with external jack-up drilling and living quarters.

The Edvard Grieg platform is designed as a field centre and will receive and process hydrocarbons from other discoveries in the surrounding area. A dedicated pipeline has been laid from the Edvard Grieg platform to the Grane oil pipeline for export to the Sture oil terminal. Similarly, a dedicated gas pipeline is laid to the SAGE transport system on the UK shelf for export of rich gas to St. Fergus in Scotland.

Three further development projects have been sanctioned in the Greater Edvard Grieg Area. An infill drilling programme on Edvard Grieg will commence in 2021 and the Solveig and Rolvsnes (extended well test) 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.
