The International Energy Agency (IEA) and KAPSARC co-hosted an expert workshop on the potential of advanced carbon dioxide (CO2 ) enhanced oil recovery (CO2 -EOR) to decarbonize oil production. The workshop focused on the potential for using CO2 -EOR for CO2 storage and increasing oil production, also known as advanced CO2 -EOR. Over the course of the two-day meeting, over 50 participants from government, industry and academia examined the current status of CO2 -EOR, explored the economic and environmental benefits of advanced CO2 -EOR and discussed the challenges facing its widespread adoption.
