Techno-Economic Assessment and Life Cycle Assessment of CO₂-EOR.

ABSTRACT: CO₂-enhanced oil recovery (EOR) can have less GHG emissions compared to conventional oil production methods. The economy of CO₂-EOR can significantly benefit from the recent rise of carbon prices in carbon markets due to its greenhouse gas (GHG) emission savings. This study conducted a life cycle assessment (LCA) of CO₂-EOR in major hydrocarbon provinces of the world. Estimated net GHG emissions of CO₂-EOR were compared with GHG emissions of average produced oil in the given country. When sourcing CO₂ from coal-fired power plants, Kazakhstan and China have net GHG emissions of CO₂-EOR of 276 and 380 kg CO₂ eq/bbl, respectively, which are lower than the GHG emission factor of average oil produced in each of them.
