Statoil is eying further opportunities in the Oseberg area after bringing its tenth fast-track portfolio project, the 77 MMboe recoverable Oseberg Delta 2, onstream.

Oseberg Delta 2 is a two-template, 14km-long subsea tieback from the Delta terrace to the Oseberg Field Centre, in the Norwegian sector of the North Sea. It came onstream on 21 February, 38 months after discovery at a cost of NOK7 billion (US$925 million).

Oseberg Delta 2 has a capacity for a total eight wells. The initial phase of the plan involves three oil producers and two gas injectors. The Oseberg Delta reserves are 3100m beneath the seabed, in 100m water depth.

An earlier two-well development from a single template has been producing oil from the Delta terrace since 2008.

Terje Gunnar Hauge, vice president for operations on Oseberg East says: “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,” says Terje Gunnar Hauge, vice president for operations on Oseberg East."

Statoil recently announced it is exploring a new unmanned wellhead platform as part of an extension of the Oseberg field development. Oseberg, which is in Blocks 30/6 and 30/9, about 130km northwest of Bergen, first came on stream in 1988 from a manned field center complex.

“Delta 2 is an important element in extending the lifetime of Oseberg. It provides a good example of how we can make lesser discoveries profitable by using existing infrastructure while it is still available,” says Arild Dybvig, vice president for fast-track development projects in Development & Production Norway.

In February, Statoil announced an increase to the recoverable resource estimates for the Krafla area to 140-250 MMboe after a two-well campaign in the area. Krafla is 25km southwest of Oseberg South.

Statoil is operator on Oseberg Delta with 49.3% interest, with partners ConocoPhillips (2.4%), Petoro (33.6%) and Total (14.7%).
