North Sea Gjoa,York tie-ins prevent premature decommissioning

摘要

LOWER OIL prices have increased the pressures on North Sea platform operators striving to delay decommissioning. This is an issue facing not just older installations that have have exceeded their design lives but also some of the newer facilities. Neptune Energy's Gjoa and Spirit Energy's York platforms were designed for long-term service on reservoirs with uncertain lifespans. Both fields have now entered the tail-end phase: Gjoa's partners have responded by instigating three simultaneous tiebacks, two of other fields in the area, to ensure continued take-up of the platform's processing capacity. Spirit is currently re-routing York's gas to another terminal providing compression in order to extend the field's lifespan by up to four years.
