Statoil is investigating a chemical leak on the world’s first wet gas compressor on the seabed of the North Sea Gullfaks field.

The aim of the technology is to increase recovery by 22 million barrels of oil equivalent (oe) and extend plateau production by around two years from the Gullfaks South Brent reservoir.

Morten Eek, a press officer for Statoil’s exploration and field development on the Norwegian Continental Shelf confirmed to Subsea World News that the company discovered a leak of 1,500 liters of barrier fluid from the compressor just one month after the start-up of the system.

Statoil said the leak was caused by a malfunction to the compressor or the compressor technology.

The company has created a technical expert group to discover where the leak occurred, and started the investigation of the incident, Morten told Sysla.

The system which consists of a 420-tonne protective structure, a compressor station with two five-megawatt compressors totaling 650 tons, and all equipment needed for power supply and system control on the platform is currently out of service and brought onshore.

The offline status on the system is not impacting the production from Gullfaks field.

Statoil could not determine how long the investigation would last and when the system would come back into operation.
