Offshore staff

HONG KONG – CNOOC has started production from the Buzzard Phase II subsea development in the UK central North Sea.

The facilities, in an average water depth of 96 m (315 ft) on the northern part of the Buzzard field, include two subsea production and two water injector wells connected to a manifold at a new drill center; and a new process, utilities and controls module on the Buzzard production platform.

An alliance of Subsea 7, AGR Well Management, Baker Hughes, COSL Drilling Europe, and Worley worked on the development over a four-year period.

Work was performed at various onshore and offshore sites including Rosenberg Worley’s fabrication yard in Stavanger, and Subsea 7’s bundle fabrication site near Wick, northern Scotland.

Subsea 7 construction vessels and the semisubmersible COSLPioneer installed the subsea equipment and drilled the wells.

At peak next year, Phase II should deliver around 12,000 boe/d, raising Buzzard’s overall production to 80,000 boe/d.

CNOOC Petroleum Europe operates with a 43.21% interest, in partnership with Suncor Energy (29.89%), Harbour Energy (21.73%), and ONE-Dyas (5.16%).
