North Sea

This paper describes how new technology was implemented and deployed through a downhole acoustic network through a sequence of runs in complex North Sea wells under managed-pressure conditions.

For the development of the Dvalin high-pressure/high-temperature (HP/HT) gas field in the Norwegian Sea, a completion scheme using standalone screens is planned.

Sharp reductions in operating expenses has rekindled growth and exploration in the UK North Sea, but this fragile recovery will require a continued luck in exploration drilling and a focus on holding the line on costs, which are still high.

The plan will extend production of the largest field on the Norwegian Continental Shelf to 2040, while also deferring plans to decommission the Statfjord A platform. Statfjord A was originally scheduled to be decommissioned in 2022.

The deal comes months after the jointly owned Petrogas NEO UK acquired several UK North Sea assets, including a $635-million purchase of Total's stakes in various fields last July. The 2-year deal with Petrofac is valued around $50 million.

The deal is part of BP’s plan to divest $10 billion in the North Sea so that it can focus on developing core growth areas and construct more cost-effective subsea tiebacks in the region.

The company will shell out more than $800 million to acquire interests in the Andrew and Shearwater areas, as well as the Tolmount field, offshore Scotland.

The unmanned development is expected to add 80 million BOE of production to the aging Norwegian North Sea field. Aker BP said it aims to produce 1 billion BOE from Valhall over the next 40 years.

As part of the contract, Wood will provide the topside modifications needed for the Snorre A and Gullfaks A platforms to integrate the Hywind floating wind park with existing systems powering the facilities. The platforms will be the first to receive electric power from floating wind turbines.

Greenpeace has been banned from carrying out climate protests on North Sea oil rigs after the oil giant Shell won a Scottish court order.
