Statoil and its licence partners have submitted the plan for development and operation (PDO) of the North Sea Oseberg Vestflanken 2 project to the Norway Petroleum and Energy Ministry.
The Oseberg Vestflanken 2 covers the Alpha, Gamma and Kappa oil and gas structures located around 8km north-west of the Oseberg field centre.

The expansion project will comprise an unmanned wellhead platform with ten well slots to produce more than 100 million barrels of oil equivalent. The wells will be remote-controlled from the Oseberg field centre.
Norwegian continental shelf (NCS) field development senior vice-president Ivar Aasheim said: "Oseberg Vestflanken 2 meets the current cost challenges and higher efficiency requirements with an innovative concept based on simplification.
"This is a pioneering project on the Norwegian Continental Shelf (NCS) that the industry can learn from."

By GlobalDataStatoil projects cluster senior vice-president Torger Rød said: "The costs of subsea templates have tripled during the last ten years.
"Platform wells on a steel jacket lead to considerable cost reductions and secure a robust project economy."
Oseberg Vestflanken 2 will serve as a vital element in further developing the Oseberg infrastructure for the future.
A new pipeline will be used to route the well stream to Oseberg field centre. Production from the well is scheduled to commence during the second quarter of 2018.
The project is the first of three planned phases for developing the remaining reserves in the Oseberg area.
Licensees in Oseberg Vestflanken 2 are Statoil (operator) (49.3%), Petoro (33.6%), Total (14.7%) and ConocoPhillips (2.4%).
