Product Description
CO2-enhanced oil recovery (CO2-EOR) stimulates oil production while storing a portion of the injected CO2. Life cycle assessment was performed for three CO2-EOR scenarios to estimate the "gate-to-gate" greenhouse gas (GHG) emissions associated with water-alternating-gas injection in a typical Permian Basin reservoir. Current CO2-EOR "best practices" generate greenhouse gas (GHG) emissions of 71 kg CO2 equivalents (CO2E) per barrel of oil extracted - approximately three times greater than GHG emissions for the average barrel of domestic oil extracted in 2005.
