Comprehensive Analysis Of CCS-EOR Economy

Climate change has become a great challenge for global decision makers in 21th century.As an important CO₂ reduction measurement,CCS-EOR is not only highly efficient in cutting emission,but can make profits by utilizing the stored CO₂,thus reducing the project cost.Based on a quantitative analysis of the economic structure of CCS-EOR process,this thesis studies the influencing factors of CCS-EOR project referring to Cointegration theory and Granger Causality theory,and the impact of those influencing according to the MIV-BP neural network model.?1?The cost structure of CCS-EOR process is analyzed.The process is divided into three parts and each one is analyzed respectively.The economic evaluation model is obtained according to relevant formulas,and the extra income of CCS-EOR is evaluated on a basis of the Ecofys&TNO model and CDM-CER revenue?2?Taking Caoshe Oilfield as an example,the specific CO₂ costs per ton of capture,transportation and storage and the proportion of total costs are obtained.Referring to this thesis,CDM-CER's revenue is extremely low considering the current oil price and CDM-CER price,and the key to making up the project cost is EOR.?3?The indicators that affect the cost of CCS-EOR projects are measured by eight related indices which are divided into three categories.After the initial data processing by heteroskedasticity test,combing with the long-run equilibrium relationship analysis guided by the Cointegration theory and the short-term causal analysis by the Granger Causality theory,the impact of each influencing factor is analyzed separately by constructing the MVP-BP neural network model.?4?The Cointegration Theory is used to quantitatively analyze the overall cost change of the CCS-EOR project when the coal price and the oil price changed.According to the thesis,it is the compression and the storage of the main energy that affects the overall project cost.When the coal and oil prices rose by 1%,the overall cost of the project rose by 0.21%and 0.13%respectively.
