Further Development in the Alvheim Area
Friday 14 August 2015
This week the first oil from the second well at Bøyla flowed the 28 kilometers to Alvheim. The Boa extension manifold were safely installed on the seabed Wednesday morning. Boa is a part of the IOR-project on Alvheim. Production start-up is expected in the second quarter of 2016.
The production vessel "Alvheim FPSO" on the Alvheim field, which consists of three licenses, also produces from three surrounding fields. The four fields are part of the greater Alvheim area; Alvheim, Vilje, Volund and Bøyla. See a overview at the bottom.
Bøyla
The Bøyla field is tied back to the Alvheim FPSO's existing infrastructure via a 28-kilometre pipeline. Bøyla is developed with a subsea installation consisting of two horizontal production wells and one water injection well. The first production well came on stream in January this year, and the second on Saturday. The second well alone, produced at a daily rate of 18,000 barrels. Along with other wells it will normally produce about 10,000 barrels of oil equivalent per day. Total production from Bøyla will be approximately 20,000 barrels per day.
The wells at Bøyla are drilled with Transocean Winner, and the subsea installation is executed by Technip on an EPCI contract.
Estimated recoverable reserves of Bøyla is estimated at about 23 million barrels of oil equivalent, of which 15 million barrels net to Det norske.
Boa expansion
Boa is located in license 088 BS, and is part of the Alvheim field. The project is part of "Alvheim IOR". Three new wells are part of this campaign, East Kameleon, Kneler, and Boa Kam North. East Kameleon came on stream in the second quarter of 2016, the Kneler well is beeing drilled now. Boa Kam North will be drilled when the well at Kneler is completed. Production start-up is estimated to the second quarter of 2016.
The steel work of Boa Kam North started on 5 May 2014 at Nymo AS, at Grimstad. Four wells can be placed in the manifold structure, making it the largest installation in the IOR-project. The manifold will be tied-in to the existing subsea solution of the Boa reservoir. The installation is executed by Technip on an installation contract
Further development
It is decided to develop Viper and Kobra in the Alvheim licence with two wells during 2016. The wells will be tied in with a new template via the infrastructure at Volund, back to the Alvheim FPSO. It will be performed by Subsea7 on an EPCI contract.
