More than 2,000 oil and gas wells are expected to be decommissioned in the North Sea over the next decade at a cost of about £20bn.
A number of decommissioning projects have been brought forward, meaning the cost has increased from an estimated £16.6bn last year.
Offshore Energies UK (OEUK) has published its annual Decommissioning Insight report, stating that an upsurge in decommissioning activity has begun this year and is expected to continue over the next three or four years.
