On behalf of the license partnerships Aker BP has submits plans for the Utsira High Project to the Norwegian Ministry of Petroleum and Energy last month. The project is a bundle of three separate subsea tie-in projects in the central part of the North Sea. Symra, previously named Lille Prinsen, will be a tie-in to the Ivar Aasen platform, while Solveig phase 2 and Troldhaugen, previously named Rolvsnes, will be connected to the Edvard Grieg platform.The Utsira High Project will develop recoverable resources of 124 million barrels oil equivalent. Drilling will commence in third quarter 2025, while production start-up is scheduled for first quarter 2026 for Solveig and Troldhaugen, and first quarter 2027 for Symra. The total investments are estimated to approximately NOK 21 billion in real terms.Aker BP is the operator for all three developments. Partners are Equinor, OMV, Sval Energi and Wintershall Dea. Separate Plan for Development and Operation will be submitted for Troldhaugen and Symra. Solveig Phase 2 is an extension of the Solveig field, and the authorities will receive a report on the development plans. All three projects are covered by the temporary tax regime adopted by the Parliament (Stortinget) in 2020.Troldhaugen is the first development on the Norwegian Continental Shelf with reservoir mainly consisting of weathered and fractured basement rock (granite). Oil deposits in bedrock have until now not been considered technically and economically viable for production because granitic bedrock is usually very dense. But if the granite is cracked and water has dissolved the minerals, it may be saturated with hydrocarbons.All producing fields on the Utsira High will be operated with electrical power from shore. Hence the CO2 emissions from the production phase will be very low.Edvard Grieg was designed and built as a field centre with the capacity to be a host platform for new fields in the vicinity. Edvard Grieg is also the host platform for the Solveig field (phase 1) and for test production from the Rolvsnes (now Troldhaugen) discovery. The Ivar Aasen field was a coordinated development with the Edvard Grieg field. Oil and gas from Ivar Aasen are transported to the Edvard Grieg platform for final processing.
