Field: DRAUGEN

General information

Current activity status:	PRODUCING
Discovery wellbore:	6407/9-1
Discovery year:	1984

Description Norwegian

Development

Draugen is an oil field in the Norwegian Sea at a water depth of 250 metres. The field has been developed with a concrete fixed facility and integrated topside. Stabilised oil is stored in tanks in the base of the facility. Two pipelines transport the oil from the facility to a floating loading buoy. The Garn Vest and Rogn Sør deposits have been developed with a total of seven subsea wells connected to the main facility at Draugen. The field also has six subsea water injection wells, of these only two are being used.

Reservoir

The main reservoir is in sandstones belonging to the Rogn Formation of Late Jurassic age. The Garn Formation of Middle Jurassic age in the western part of the field is also producing. The reservoirs lie at a depth of about 1 600 metres and are relatively homogenous, with good reservoir characteristics.

Recovery strategy

The field is produced by pressure maintenance from water injection and aquifer support.

Transport

The oil is exported by tankers via a floating loading buoy. The associated gas is transported by the Åsgard Transport pipeline to Kårstø. In periods without gas export, excess gas can be injected in a separate structure east of Draugen.

Status

Several measures to increase oil recovery have been evaluated. Based on a 4D seismic survey carried out in 2009, the potential of new wells on the field is being evaluated. Final decision for infill drilling is planned in 2011. The discovery 6407/9-9 (Hasselmus) is planned to be phased in to the Draugen facility, and a decision regarding development is expected in 2011. Gas from this deposit can be utilised as fuel gas on Draugen. Draugen is also being evaluated as host for the 6406/9-1Linnorm discovery.
