Jun 19, 2012 – Statoil reported that the Valemon jacket was successfully delivered and installed on the field, which lies in the Norwegian sector of the North Sea. The 9,000-ton steel jacket was carried out as planned and the project remains on schedule. The jacket, which was built by Heerema Fabrication Group in Vlissingen in the Netherlands, was transported from the shipyard and out to the field by the crane barge Thialf. Development of Valemon involves a fixed platform with a steel jacket for the separation of gas, condensate and water. The rich gas will be transported via a new pipeline to the existing pipeline from Huldra to Heimdal for further processing. The condensate will be piped to the Kvitebj??rn platform for stabilization and further transport via the Troll oil pipeline to the Mongstad refinery. At peak production, Valemon is expected to deliver roughly 86,000 barrels of oil equivalent per day. The field is expected to come on stream in the fourth quarter of 2014 and has a life expectancy of 11 years.

Jun 15, 2012 – Statoil has submitted a plan for development and operation for the Svalin field to the Norwegian government and reported it expects to bring the field online in 2013. Recoverable reserves at the field are estimated at around 75 million barrels of oil equivalent, with two structures Svalin C and Svalin M containing similar quantities. The Svalin C and Svalin M discoveries will be developed through a ‘fast-track’ method that uses a standard solution involving processing by existing infrastructure. 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 connected via a four-mile long flowline to the Grane platform. The hydrocarbons will utilize 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, along with production from the Grane field, through the existing pipelines for storage and shipment from the oil terminal at Sture.
