We expect 247 fields to cease and US$20 bn to be spent on decommissioning between 2018 and 2022. Companies in the North Sea are bracing themselves for an imminent wave of decom. Shell, ExxonMobil and Total (including Maersk) have the most to do. They will spend roughly US$2 billion each in this period. However, North Sea decommissioning is relatively immaterial for the Majors, accounting for only 2% of global capex. Conversely, for five companies, North Sea decommissioning spend accounts for more than 25%.
