STAVANGER, Norway – Statoil and its partners have submitted the plan for development and operation (PDO) for the Oseberg Vestflanken 2 in the North Sea.
The development will consist of an unmanned wellhead platform with 10 well slots. The wells will be remote-controlled from the Oseberg field center. Two existing subsea wells will also be reused and the well stream will be routed to Oseberg field center via a new pipeline.
The development cost is projected at NOK 8.2 billion ($936 million), and is expected to recover 110 MMboe. Production start-up is scheduled for the 2Q 2018.
Wellhead platforms with no facilities, helicopter deck or lifeboats represent a new solution in Norway, but it has been thoroughly tested in other areas, such as the Danish and Dutch continental shelves. c
Oseberg Vestflanken 2 is the first of three planned phases for developing the remaining reserves in the Oseberg area. The licensees are: Statoil (operator and 49.3%), Petoro (33.6%), Total (14.7%), and ConocoPhillips (2.4%).
Tomas Mørch, assistant director for the North Sea North in the Norwegian Petroleum Directorate (NPD), has deemed Oseberg Vestflanken 2 to be a good project for further development of the area: “I think it’s positive that the Oseberg licensees have decided on a project for improved recovery in these demanding times.”
The NPD encourages companies to consider unmanned wellhead platforms more often in relation to seabed developments, when development decisions are made.
