Ivar Aasen field in North Sea produced its first oil on schedule and the project being completed within the estimated budget, operator Aker BP said.
Production started on Dec. 24, four years after the Plan for Development and Operation (PDO) was submitted. The plan was to start up production in fourth quarter 2016.
“As operator, we have completed the development in a challenging period for the industry,” said Karl Johnny Hersvik, chief executive of Aker BP. “It is therefore satisfying that we have delivered within budget and on time. For me it is even more important that the project has been carried out without any serious incidents.”
The economic life of Ivar Aasen field may be 20 years, depending on oil prices and production development. Aker BP utilizes modern technology to operate the field most efficiently with low staffing. Operations will be run from an operations centre in Trondheim.
“There are still major challenges in our industry, and continuous improvement in the way we operate is essential. Aker BP is well positioned to meet these challenges in partnership with our suppliers, he said.
The Utsira area
The Ivar Aasen field is located in the northern part of the North Sea, about 175 km west of Karmøy, and contains around 186 million barrels of oil equivalent (boe), excluding Hanz. The latter will be developed in phase two of Ivar Aasen development, and amounts to about 18 million barrels of oil equivalent. Net Aker BP, including Hanz, represents approximately 71 million boe.
The development of the Ivar Aasen includes deposits for five licenses, 001B, PL028 B, PL242, PL338 and PL457. The unitization of the licenses covers deposits in Ivar Aasen and West Cable. Hanz deposit in license PL028 B is not covered by the unitization.
In alignment with the government’s desire this is a coordinated development with neighboring field Edvard Grieg. Oil and gas from Ivar Aasen is processed and exported from Grieg platform, which also supplies power to Ivar Aasen.
This summer the topside of about 15,000 tons was lifted into place on the field. It was completed without problems and according to plan. During the last six months, between 400 and 500 people have been working offshore to prepare for production start-up.
A substantial proportion of the deliveries for the project come from Norway, and the main part of the platform deck is built in Singapore. The living quarters, which was lifted onto the deck, is built at Stord. The chassis, built in Sardinia, was installed in summer 2015. Altogether over five thousand people worked on the construction of Ivar Aasen.
