Field: STATFJORD NORD

General information

Current activity status: PRODUCING
Discovery wellbore: 33/9-8
Discovery year: 1977

Description Norwegian

Development

Statfjord Nord is an oil field located approximately 17 kilometres north of Statfjord in the Tampen area. The water depth in the area is 250 - 290 metres. The field has been developed with three subsea templates tied back to Statfjord C. Two of the templates are for production and one is for water injection. One well slot is used for water injection at the Sygna field.

Reservoir

The Statfjord Nord reservoirs consist of Middle Jurassic sandstones of the Brent Group (Tarbert, Etive and Rannoch Forma-tions), and Upper Jurassic sandstones. The reservoirs lie at a depth of approximately 2 600 metres and are of good quality.

Recovery strategy

The field produces with partial pressure support from water injection.

Transport

The wellstream is routed through two pipelines to Statfjord C for processing, storage and export. Statfjord Nord, Sygna and Statfjord Øst have a shared process module on Statfjord C.Status: The current key challenge is to restore pressure maintenance. The plan is to repair the second water injector early 2013. Water alternating gas injection (WAG) has been evaluated and rejected.
