Statoil and its partners in the Svalin field have today, 15 June, submitted their plan for development and operation (PDO) to the Ministry of Petroleum and Energy.
The Svalin field lies about six kilometres south-west of the Grane platform at a water depth of 125 metres.
The Svalin field development is one of Statoil’s fast-track developments. Statoil is operator; Petoro and ExxonMobil are partners.
Recoverable reserves are estimated to about 75 million barrels of oil equivalent (12 million standard cubic metres o.e.). There are two structures, Svalin C and Svalin M, containing similar quantities.
The Svalin development will be tied back to the Grane platform. Svalin M will be produced by a well drilled from the Grane platform, while Svalin C will be a subsea development with a six-kilometre-long flowline to the Grane platform. The hydrocarbons will utilise shared processing and export facilities.
The gas compression facility at the Grane platform will be modified to handle gas from Svalin.
Oil from the Svalin development will be transported, with production from the Grane field, through the existing pipeline for storage and shipment from the oil terminal at Sture.
Svalin M was discovered in 2008 and its start-up is scheduled for the end of 2013. Svalin C was discovered in 1992 and its start-up is scheduled for summer 2014.
The Svalin development will use available process capacity and mitigate the decline of oil and gas processed on the Grane platform.
Aker Subsea AS has been awarded the contract for the subsea production system and the pipeline and marine operations are to be performed by Subsea 7.
Svalin is the eighth development in Statoil’s portfolio of fast-track developments. The criteria are that a standard solution can be used and processed by the existing infrastructure. These fast-track developments will deliver significant production and the ambition is an aggregate production of 100,000 barrels of oil equivalent per day by 2014.
