15/06/2012 The Norwegian Petroleum Directorate has received plan for development and operation (PDO) of 25/11-16 Svalin in the North Sea.
The Svalin field is located approximately six kilometres southwest of the Grane facility. Statoil is the operator with an ownership interest of 57%; the other licensees are Petoro (30%) and ExxoMobil (13%). The licensees are planning to invest a total of NOK 4.46 billion in this development.
Recoverable reserves on Svalin are estimated at approximately 12 millions standard cubic metres of oil. The reserves are divided equally between the two deposits Svalin C and Svalin M.
According to the plan, Svalin will be a combined development tied in to Grane where Svalin M will be produced through a double branch well drilled from the Grane facility, while Svalin C will be a subsea well tied in to Grane through a six kilometre long production flow line. According to the plan, there will be a joint processing and export solution.
Svalin C was discovered in 1992, and production is scheduled to start in June 2014. Svalin M was discovered in 2008, and production start is scheduled for November 2013.
"Last week the NPD received the PDO for Bøyla, and this week we have received the PDO for Svalin. Both are good examples of minor developments phased into the existing infrastructure. This contributes to good area solutions, as well as good utilisation of infrastructure, both of which are important to the NDP", says Kjetil Aasoldsen, Director of North Sea South in the Norwegian Petroleum Directorate.
The licensees in the coordinated Grane field, where Statoil is the operator, own the facilities.
According to plan, the Svalin oil will be transported together with Grane's own production in the existing pipeline from Grane for storage and shipment from the oil terminal at Sture. The gas compression installation on Grane will be modified to be able to process gas from Svalin. The metering installation will also be upgraded.
The licensees expect the field to continue production up to 2030.
Plans for development and operation (PDO) and plans for installation and operation (PIO) comprise a development or construction section and an impact assessment section. PDOs/PIOs must be submitted to the MPE and the Ministry of Labour (AD) with a copy to the NPD and the Petroleum Safety Authority Norway (PSA).
For PIOs for gas transport and processing, or PDOs including processing of gas transport in pipelines, Gassco must also receive a copy. The MPE coordinates the processing of the plan. AD, NPD and, if relevant, Gassco will submit their assessments to the MPE, while the PSA submits its assessment to AD.
