Brynhild output restarting offshore Norway

Production from Brynhild oil field in the southern part of the Norwegian North Sea is restarting after having been shut down by equipment problems in mid-January.

Production from Brynhild oil field in the southern part of the Norwegian North Sea is restarting after having been shut down by equipment problems in mid-January.

The field started up on Dec. 25 (OGJ Online, Jan. 16, 2015). Problems related to the Haewene Brim floating production, storage, and offloading vessel on Pierce field forced the shutdown.

Brynhild is in 80 m of water on Blocks 7/4 and 7/7 about 55 km northwest of Ula field and 38 km north of Pierce, which is in UK waters.

Brynhild operator Lundin Norway said a leak in the gas-injection flexible line has been repaired. Repair has begun on a damaged connection between one of the mooring chains and the riser buoy.

The company said initial flow confirmed the field’s ability to produce at the expected plateau rate of 12,000 b/d.

The Maersk Guardian jack-up rig has finished drilling the third well in a four-well program, which it will complete while drilling of the fourth well is in progress.

Lundin estimates proved and probable reserves at 23.1 million boe. The hydrocarbons are in Late Jurassic Ula sandstone at a depth of 3,300 m.

Three of planned wells are producers, with lengths up to 5,000 m and horizontal sections as long as 1,000 m. One well is a water injector. After a year of production, one of the producers will be converted to water injection.

The wells are completed subsea and tied back to Pierce field.

Lundin holds a 90% interest. Talisman Energy Norge holds the rest.
