The Ivar Aasen field is Det norske’s first major development project as operator. On 21 May 2013, the Plan for Development and Operation (PDO) was approved by the Storting. The company is all set for implementing the project according to plan, schedule and costs. The first oil is expected produced in the fourth quarter of 2016. Det norske holds a 35 percent interest in the field, and partners are Statoil (50 percent) and Bayerngas Norge (15 percent).
The Ivar Aasen field is situated west of the Johan Sverdrup field in the North Sea, and contains approximately 150 million barrels of oil equivalents. Det norske’s share of production is approximately 16,000 barrels of oil equivalents per day from Q4 2016 and 23,000 barrels per day at plateau in 2019. Total investments in the project are estimated at NOK 24.7 billion. The anticipated economic life of Ivar Aasen is 20 years, depending on oil price and production trend. With the prevailing oil price, expected gross revenues throughout the anticipated lifetime of the field amount to approximately NOK 100 billion.
The discoveries The Ivar Aasen development comprises production of the resources in three discoveries; Ivar Aasen (PL 001B) Hanz (PL 028B), and West Cable (PL 001B and PL 242). The discoveries are located in blocks 16/1 and 25/10 between the southern Viking Graben and the Utsira High in the northern part of the North Sea, approximately 175 kilometres west of Karmøy.
Det norske discovered Ivar Aasen in 2008 with well 16/1-9, drilled on the then Draupne prospect, which proved hydrocarbons in sandstone of Middle Jurassic and Upper Triassic age.
Hanz was discovered by Esso in 1997 with well 25/10-8, drilled in prospects of Middle Jurassic and Palaeocene age. Esso also drilled the West Cable prospect in 2004, with well 16/1-7, and discovered oil in Middle Jurassic sands.
The development solution The license partners have decided on a joint development project including all three discoveries. The plan is to develop Ivar Aasen as a phased development, whereby Ivar Aasen and West Cable are developed in phase 1, and Hanz in phase 2.
The fields are being developed with a manned production platform located above the Ivar Aasen reservoir and a subsea installation on Hanz tied to the Ivar Aasen platform by means of a flow line and umbilical system. West Cable will be drained through a well drilled from the Ivar Aasen Platform.
Following orders issued by the authorities, the development of Ivar Aasen is coordinated with the adjacent Edvard Grieg field, which will receive partially processed oil and gas from the Aasen field for further processing and export. The Edvard Grieg platform will also provide the Ivar Aasen platform with gas lift and electricity. The Aasen platform is electrified from the start-up.
Contracts During 2013, Det norske has awarded several of the Ivar Aasen development contracts. The platform deck is 13 700 tonnes and is to be constructed by SMOE in Singapore, and sail away is scheduled for March 2016. The contract is worth approximately NOK 4 billion. The living quarters module for Ivar Aasen will be build by Apply Leirvik at Stord. The steel jacket is to be constructed by Saipem on Sardinia. The height of the jacket is 138 metres, and the weight, piles included, totals 14 400 tonnes. The contract is worth NOK 709 million.
Operated from Trondheim The Ivar Aasen field is developed and operated from Trondheim. Det norske aims to make use of state-of-the-art technology, ensuring efficient operation and low offshore staffing. An operation centre with control room will be established in Trondheim. The Ivar Aasen development will require approximately 2000 full-time equivalents.
