Assessing risks presented by boreholes: Recommendations on a risk assessment framework for CO2 storage
The deliverable D3.2 of the ENOS project is freely available
One of the key elements in CO2 storage is to ensure the process is safe and avoid any leakage. Around the world, 23 large scale CCS facilities have been safely operated, including the Val Verde CO2-EOR operation in the US since 1972 and the Sleipner CO2 storage operation offshore Norway since 1996 (GCCSI report, 2018). Nevertheless, the task of properly assessing leakage risk, even if very low, is vital for safety of operation, permitting, and public awareness and acceptance of the CCS technology.
