Over two thousand North Sea wells involved in oil and gas extraction are to be decommissioned at a cost of around £20bn over the next decade, says a new report by Offshore Energies UK (OEUK).
The report finds UK decommissioning is expanding fast and predicts a surge in activity over the next 3-4 years. It says the sector will continue growing as other emerging offshore energy technologies, like offshore wind farms, also require the service.
It is estimated around 2,100 North Sea wells will be decommissioned over the next decade – around 200 per year – at an average cost of £7.8m per well.
In 2021 a tenth of UKCS oil and gas expenditure went into decommissioning. This proportion has risen to 14% in 2022 and is set to rise to 19% by 2031. Over the next decade, expenditure on decommissioning is predicted to total £19.7 billion, with well decommissioning comprising nearly half of this spend.
The report authors say over 75% of total decommissioning spend will be within the central North Sea, (stretching from Yorkshire to the northern tip of Scotland), and the northern North Sea, (covering an area north of Scotland and east of Shetland and Orkney).
However, the growth in other renewable energies, such as offshore wind, could cause bottlenecks in demand for decommissioning services, the report says.
It means the offshore wind, carbon capture and storage, and oil and gas sectors will need to work together and be transparent about planned projects to make sure the opportunity is properly managed.
OEUK Decommissioning Manager Ricky Thomson said: “The UK’s decommissioning sector is snowballing and will continue growing for years to come. But this poses a challenge as well as an opportunity. The growth of renewables and demand for decommissioning services and expertise will create increasing pressure for resources. This is a great problem to have and it’s vital this opportunity is properly managed across the sector so that UK firms can capture the lion’s share of this £20bn opportunity.”
