Study Notes

Carbon Capture and Storage (CCS) and Enhanced Oil Recovery (EOR) Key Points

Immiscible CO2 flooding examples include SACROC unit and Denver Unit of Wasson Field
USA is not mentioned as a planned CCS hub
CO2 sequestration for EOR is primarily to enhance oil recovery
Natural gas injection is not mentioned as a type of CO2 storage
Coal bed methane production involves CO2 storage in un-minable coal seams
Natural gas injection is not mentioned as a method of primary, secondary, or tertiary recovery
The objective of 'Advanced' CO2-EOR is to maximize CO2 sequestration and offset costs by producing oil
The break-even cost for Advanced CO2-EOR is $22$32 / Tonne of CO2
Tax credits for CO2 permanently stored and used in EOR are $85 per tonne and $60 per tonne respectively
The proposed Midwest CO2 Superhighway is expected to sequester up to 40 million tonnes of CO2 annually
Water Drive is the primary recovery method using the reservoir's own energy
The estimated total storage capacity of CO2 in the Weyburn Field is approximately 55 Mt CO2
