Statoil starts up Oseberg tieback offshore Norway

Offshore staff

STAVANGER, Norway – Production has started from the satellite Oseberg Delta 2 development in the Norwegian North Sea. Operator Statoil estimates the field’s recoverable reserves at 77 MMboe.

Oseberg Delta 2 is the tenth project in Statoil’s fasttrack portfolio. The partners sanctioned the development in December 2011 and received approval for the development plan from Norway’s parliament nearly two years later.

The accumulation is tied back to the Oseberg field center 14 km (8.7 mi) to the north via two subsea templates that can accommodate eight wells. Initial development involves three oil producers and two gas injectors.

Statoil says the cost – just under NOK 7 billion ($920 million) – is well below the estimate at the time the project was sanctioned. Oseberg Delta 2 is a further development on the Delta terrace where oil from two wells has been produced since 2008 from an existing subsea template.

Use of gas injection should lead to a substantially greater recovery rate, an official said.

“There are also some good opportunities for the further development of the area and an exploration well has already been planned in the southern part of the Delta terrace,” added Terje Gunnar Hauge, vice president for operations on Oseberg East.

Statoil’s partners are ConocoPhillips, Petoro, and Total.
