STAVANGER, Norway – Norwegian independent Noreco has to contend with downtime and production issues at its various fields in the North Sea.

Offshore Denmark, production from the DONG-operated Nini,Nini East, and Cecilie fields has been shut down temporarily as a precaution. This follows anomalies that came to light during a routine inspection of a bulkhead subsea connected to the host Siri platform.

The Lulita field also remains shut in due to an unsuccessful repair of an emergency shutdown valve in the Harald subsea gas export pipeline. Operator Maersk estimates work to rectify the situation and re-start production could take five to 10 weeks.

At the DONG-operatedOselvar field in the southern Norwegian North Sea, scale removal from the produced water facilities on the host Ula platform is taking longer than anticipated. BP expects Oselvar to remain shut in until around July 24.

In the UK central North Sea, oil rates from the EON Ruhrgas-operatedHuntington field have improved as commissioning of the gas facilities on the FPSO progresses. Currently, the facility is handling about 24,000 b/d of oil and 19 MMcf/d (538,020 cm/d) of export gas.

So far the production systems have performed reliably, although there could be some disturbances as certain process equipment items are worked on and calibrated.

Only one of the two high-pressure compressors (the B-train) is operating. The A-train vibration issue continues, and the turbine is undergoing re-balancing. EON Ruhrgas expects the A train to be operational within the next few weeks.

As soon as full gas compression capability is available, Noreco adds, oil production from Huntington is expected to ramp up to 30,000 b/d.
