Significance of Enhanced Oil Recovery in Carbon Dioxide Emission Reduction

Limiting the increase in CO2 concentrations atmosphere, and at same time, meeting increased energy demand can be achieved by applying carbon capture, utilization storage (CCUS) technologies, which hold potential as bridge for emission-intensive industries to decarbonization goals. At moment, only profitable industrial large-scale sequestration projects are dioxide enhanced oil recovery (CO2-EOR) projects. This paper gives a general overview of indirect direct use captured CCUS with special focus on worldwide CO2-EOR their lifecycle emissions. On basis scientific papers technical reports, data from 23 contemporary different project stages were aggregated, pointing out all specificities The individual projects, along lack standardized methodologies specific estimating full emissions resulting pose challenge contribute uncertainties wide flexibilities when making cross-referencing its comparison other climate-mitigation strategies rather difficult. Pointing mentioned project’s differentiations aggregating an useful information future work topic
