The wellhead facility has 10 well slots, two of which will be used to inject gas. Additionally, two production wells will be drilled from an existing subsea template on Vestflanken.
Further injection will take place by bringing in gas through a new pipeline from an existing gas injection system. The wells on Vestflanken 2 will be controlled from the Oseberg field center, where the oil and gas will also be processed.
Statoil is operator of Vestflanken 2 with 49.3% interest. Partners are Petoro AS 33.6%, Total SA 14.7%, and ConocoPhillips 2.4%.
ConocoPhillips in 2015 estimated development cost at just under $1 billion, facilitating production of 110 million boe. Of the total, oil represents 62 million bbl, while gas amounts to 7.8 billion standard cu m. The reservoirs are 2,400-3,100 m subsea.
