Subsea Boost for Alvheim
The Boa extension manifolds were safely installed on the seabed Wednesday morning as a part of the Improved Oil Recovery (IOR) project on Alvheim, Det norske’s core area of production.
According to the company, Boa 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.
The Bøyla field is tied back to the Alvheim FPSO’s existing infrastructure via a 28-kilometre pipeline. This Saturday, the first oil from the second well at Bøyla flowed to Alvheim. 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. 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 subsea installation at Bøyla 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.
In addition, Boa is one of three wells in Alvheim IOR campaign, East Kameleon, Kneler, and Boa Kam North. East Kameleon came on stream in the second quarter of 2015, the Kneler well is beeing drilled now. Boa Kam North will be drilled when the well at Kneler is completed.
The steel work of Boa Kam North started on May 5, 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.
Furthermore, Det norske informed that it has been 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 Subsea 7 on an EPCI contract.
