Ivar Aasen

The Ivar Aasen field is Det norske’s first major development project as operator. ivar aasen hovedlogo rgbThe field development project is progressing according to schedule towards a planned start-up in the fourth quarter 2016. Det norske is the operator of the unitized development, with a 34.7862 percent interest. Partners are Statoil, Bayerngas, Wintershall, VNG, Lundin and OMW. 

Unit agreement

The Ivar Aasen development compromises resources in five fields, PL 001B, 028B, 242, 338 and 547. The licencees in the five fields signed an agreement, witch establishes the ownership interest in the unitized field, in June 2014. Det norske is the operator with 34.7862 percent ownership interest.

The unit agreement comprises the Ivar Aasen and West Cable deposits. The Hanz deposit remains in PL 028B, where Det norske is operator and has 35 percent interest. Hanz is planned to be developed in phase 2 of the Ivar Aasen development.

IvarAasen_Hanz_GriegThe Ivar Aasen field is situated west of the Johan Sverdrup field in the North Sea, and contains approximately 210 million barrels of oil equivalents, Hanz deposit included. Net to Det norske, this amounts to about 74 mmboe.

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.

The field development is progressing according to schedule towards a planned start-up in the fourth quarter 2016. In the first week of November 2013, the first steel was cut at SMOE’s yard in Batam in Indonesia, and at Saipem’s yard in Arbatax, Sardinia. At the same time, the work on the platform deck started at the yard in Singapore.

The discoveries

The first phase of the Ivar Aasen development comprises production of the resources in two discoveries; Ivar Aasen (PL 001B) and West Cable (PL 001B and PL 242) in the northern part of the North Sea, approximately 175 kilometres west of Karmøy.

Hanz in the neighboring licence 028B is planned to be developed in phase 2 of the Ivar Aasen development.

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.

Ivar Aasen

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. Siemens will deliver the control- and communication systems for the platform.

Det norske has, together with the partners, employees and contractors developed a united HSE commitment, ZERO. Zero HSE incidents, Engaged and committed leadership, Reliable and proactive HSE knowledge sharing, Open and honest culture. Read more about the Ivar Aasen HSE commitment HERE.

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.

This is how we develop Ivar Aasen
