STAVANGER --StatoilHydro has contracted Framo to devise a subsea wet gas compression system for its Gullfaks South field in the Norwegian North Sea.
The aim is to boost recoverable reserves of wet gas from the field by 3 bcm, 6% more than the current estimate.
Gullfaks South is tied back to the Gullfaks C platform via three 15-km (9.3-mi) pipelines. Subsea compression would allow StatoilHydro to compress the gas closer to the reservoir rather than on the platform, explained Gullfaks 2030 head Ingrid Honsi.
It would also allow the company to make better use of electrical power and draw gas more easily from the reservoir to the platform, thereby improving recovery.
Longer term, the aim is to extend this technology to more and larger fields.
