UK Approves Chrysaor’s MacCulloch Subsea Decommissioning Programme

UK oil and gas authorities have approved Chrysaor’s MacCulloch subsea installations decommissioning programme in the North Sea.

The selected option for the facilities is to remove, dismantle and dispose of them, ensuring a high level of material recycling.

The MacCulloch field, located in UK Central North Sea Block 15/24b, was developed in 1996/97 with the expected life of ten years.

Production started in August 1997 via the North Sea Producer floating production storage and offloading (FPSO) unit, owned by the North Sea Production Company (NSPC).

Producing around 60,000bbl/day at its peak, production declined to around 7,200 bbl/day gross with five wells remaining online and an average water cut of ~88% prior to the MacCulloch
cessation of production.
