Key considerations for re-purposing mature wells and fields for Carbon Capture and Storage (CCS)
Traditionally, when an oil and gas field production cycle end and all usable hydrocarbons have been extracted, the top side facilities are dismantled, the wellbore is permanently plugged and abandoned, and the surrounding land or seabed is returned to its natural condition. In the UK Continental Shelf (UKCS) alone, it is forecast that 1,211 wells across 230 fields will be decommissioned between 2019 to 2028. The current projected decommissioning costs for the UKCS total $60 billion with efforts underway to reduce that figure to $51 billion by the end of 2022.
