Equinor said Oct. 15 that the Oseberg Vestflanken 2 field in North Sea started production on Oct. 14 using the first unmanned, remote operated wellhead platform on the Norwegian Continental Shelf.
The platform, called Oseberg H, weighs 1,000 tonnes and is remote operated from the Oseberg field center. The platform will drill nine wells in the Oseberg Vestflanken 2 accompanying the 11 wells to be drilled by the Askepott jack-up rig and the two more, which will be done an existing subsea template. Pipelines and subsea equipment have also been installed.
"Oseberg H is a pilot and our first unmanned platform," said Anders Opedal, Equinor executive vice president for technology, projects and drilling. "We are further developing the concept and believe that the next version will be even more competitive."
In addition, the company also noted that the project was delivered below budget at 6.5 billion Norwegian kroner, more than 20% lower than 8.2 billion kroner estimate used in the plan for development and operation.
The Oseberg Vestflanken 2 field is about 8 kilometers northwest of the Oseberg field's center in water depths of around 110 meters and is said to have recoverable resources of more than 110 million barrels. The field is expected to be productive until 2040.
Equinor subsidiary Equinor Energy AS holds a 49.3% stake in the Oseberg Vestflanken 2 production license while Petoro AS, French oil major TOTAL SA subsidiary Total E&P Norge AS and ConocoPhillips subsidiary ConocoPhillips Skandinavia AS own interests of 33.6%, 14.7% and 2.4%, respectively.
As of Oct. 15, US$1 was equivalent to 8.15 Norwegian kroner.
