AGR’s Well Management has been working alongside Baker Hughes, COSL Drilling Europe, Subsea 7 and Worley as part of a supply chain alliance to deliver CNOOC Petroleum Europe Limited’s (CNOOC Europe) Buzzard Phase II (BPII) development, which has now safely commenced production.

  • CNOOC Petroleum Europe Limited’s Buzzard Phase II development achieves first oil
  • Supply chain alliance includes Baker Hughes, AGR, COSL Drilling Europe AS, Subsea 7 and Worley

The alliance was formed to offer an integrated and outcome-focused approach for the development. The alliance and CNOOC Europe have worked collaboratively to safely achieve first oil within the sanctioned budget and ahead of the revised schedule, which was significantly impacted by COVID-19.

This achievement is the result of a collective effort over a four-year period by the BPII project alliance companies, as well as a long list of key suppliers and sub-contractors.

Buzzard Phase II project milestones

The work was carried out across a range of onshore and offshore worksites. These included:

  • the Buzzard asset
  • Rosenberg Worley’s fabrication yard in Stavanger
  • Subsea 7’s bundle fabrication site near Wick
  • various Subsea 7 construction vessels
  • COSL Drilling Europe’s COSL Pioneer semi-submersible drilling rig.

More than 2.6 million hours were expended by an integrated team. This team worked under an innovative alliance contracting model which provided greater flexibility to quickly adapt to changes, including the global pandemic. The model allowed teams to combine their strengths.

Svein Sollund, CEO of AGR, said, “We are delighted to have been involved as part of the alliance. The AGR team have delivered their best experience and practice. We have gathered this throughout the company’s 30 years’ history, and unrivalled track record of more than 550 wells.

AGR’s role as Well Engineering and Drilling Project Manager supported the alliance to complete the multiple subsea well campaign.

I am really impressed to see how all different partners and disciplines came together as one. They delivered such substantial project safely and cost effectively.”


BPII is a subsea development in the Northern Area of the Buzzard field. It is located approximately 100 kilometers northeast of Aberdeen, with average water depth of approximately 96 meters. The field currently consists of two producer wells and two water injections wells. The installation also includes a subsea production and water injection manifold located at a new drill center, tied back to the existing Buzzard facility.
