in 2018. The field has been developed with a concrete fixed facility and integrated topside. Stabilized oil is stored in tanks in the base of the facility. Two flowlines connect the facility to a floating loading buoy. The Garn Vest and Rogn Sør deposits have been developed with a total of five subsea wells connected to the main facility at Draugen. The field has six subsea water injection wells. Additional resources in the Garn Vest structure came on stream in December 2001, while development of additional resources at the Rogn Sør structure were approved in the spring of 2001, coming on stream in January 2003.

Reservoirs

The major reservoir is the Rogn Formation, a shallow marine

Spills

In January 2008, a small amount of oil was spilled after a pipe broke while loading a tanker. The oil being loaded into the Navion Scandia tanker was spilled when the pipeline pressure became too high. The oil spilled was in such a small amount that much of it evaporated before being contained.

Current status

New production wells are currently being drilled and more is being considered to increase output.
