Draugen oil field

Draugen is an oil field in the Norwegian Sea with a sea depth of 250 metres (800 ft). It had been operated by A/S Norske Shell until sold to AS OKEA 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.

Reservoirs

The major reservoir is the Rogn Formation, a shallow marine sand bar of the Late Jurassic at around , while on the western side of the field is the Garn Formation of the Middle Jurassic. They are all producing reservoirs with good characteristics. ==Recovery and transport==

Recovery and transport

The platform consists of a concrete mono-column with integrated deck. Oil transport is accomplished through tanker via floating buoy. The Asgard transport pipeline is used for transport of natural gas to Kårstø. ==Removing the rig==

Removing the rig

In January 1997, it was decided to dispense with the maintenance-intensive drilling package on the Draugen platform because the well programme had been completed. In 2003 it was sold to Russia and installed on the ship Ispolin for drilling in the Russian sector of the Caspian ==Spills==

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==

Current status

New production wells are currently being drilled and more is being considered to increase output. Gas injection and water injection are used to increase production. CO2 injection has been rejected. ==Climate==
