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
Test your knowledge of key points related to Carbon Capture and Storage (CCS) and Enhanced Oil Recovery (EOR), including examples, planned CCS hubs, CO2 sequestration for EOR, and storage methods.
