Nexen Petroleum has announced that the Buzzard Phase II (BPII) Project has received full sanction from partners (Suncor Energy UK Limited, Chrysaor Limited, Dyas EOG Limited and Oranje-Nassau Energie Resources Limited) and the Field Development Plan has been approved by the UK Oil and Gas Authority.

Located about 96 km northeast of Aberdeen in 96 meters of water, the Nexen-operated Buzzard platform is the largest UK North Sea oil discovery in the past two decades. BPII is a subsea development of the Buzzard northern area. The objective of this project is to safely develop additional reserves and bring new production on stream, supporting the goal of maximizing economic recovery in the North Sea.

BPII is using an integrated project team, comprised of Nexen Petroleum UK Limited and supply chain partners AGR Well Management Limited, Baker Hughes, a GE Company (BHGE), COSL Drilling Europe AS, Subsea 7 Limited and WorleyParsons Services UK Limited.

COSL Drilling Europe has signed an agreement for the semi-submersible rig COSLPioneer for drilling at the Buzzard Phase II Project for Nexen Petroleum off the UK. The drilling campaign will commence in February 2019 and comprise at least 6 wells. The expected duration is around 16-18 months.

The selected concept is a subsea development of the Buzzard northern area, approx. 5 km NE of Buzzard consisting of a 12-slot manifold (8 Production slots and 4 Water Injection). The development will be tied back to the existing Buzzard complex with a pipeline bundle assembly incorporating pipelines, manifolds, subsea controls and chemical injection. A brownfield module is to be installed on the Production Platform for processing and export via current export pipeline routes.

First oil is expected Q1 2021.
