Development
Draugen is a field in the southern part of the Norwegian Sea. The water depth is 250 metres. Draugen was discovered in 1984, and the plan for development and production (PDO) was approved in 1988. The field has been developed with a concrete fixed facility and integrated topside, and has 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. Production started in 1993.Reservoir
Draugen produces oil from two formations. The main reservoir is in sandstone of Late Jurassic age in the Rogn Formation. The western part of the field also produces from sandstone of Middle Jurassic age in the Garn Formation. The reservoirs lie at a depth of 1,600 metres. They are relatively homogeneous, with good reservoir quality.Recovery strategy
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. The associated gas was earlier transported via the Åsgard Transport System (ÅTS) to the Kårstø terminal, but is now used for power generation on the platform.Status
With declining oil production, volumes of associated gas will not be sufficient for power generation, and alternative solutions are therefore being evaluated, including power from shore. The gas discovery 6407/9-9 (Hasselmus) is under development for subsea tie-back to the Draugen platform. Identification and maturing of infill targets are ongoing in order to increase the recovery from the field. A lifetime extension for the facility is required to maintain the forecasted production profile.ACCRUED INVESTMENTS IN NOMINAL NOK
