This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with identification of the main business risks facing a company engaged in geological sequestration. Such risks include both the operational risks of capturing, compressing, transporting and injecting CO2, as well as the risk of accidental, rapid CO2release from wells (including an analysis of blow out data from CO2injection wells, worked over wells as well as abandoned wells). Observations of the outcomes from accidents in real pipelines and CO2injection wells in CO2-EOR projects provide the most concrete basis to predict the future safety of the above ground operations of CO2sequestration in deep brine reservoirs. © 2009 Elsevier Ltd.
