Draugen

Draugen is an oil field with associated gas in the southern part of the Norwegian sea.

The water depth in the area is 250 metres. Draugen was discovered in 1984 by Shell, the plan for development and operation (PDO) was approved in 1988, and with production start in 1993.

Development

The field was developed using a fixed concrete facility with integrated topside and production is from both platform and subsea wells. Stabilised oil is stored in tanks at the base of the facility. Two pipelines connect the facility to a floating loading-buoy.

Reservoir

Draugen produces oil from two formations. The main reservoir is in sandstone of late jurassic age (the rogn formation) while the Western part of the field also produces from sandstone of Middle Jurassic age (the garn formation). The reservoirs lie at a depth of 1,600 metres, are of good quality and relatively homogeneous across the field.

Recovery

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

Transport

The oil is offloaded via a floating loading-buoy and exported by tankers. Associated gas is currently used for power generation.
