Analysis of Economic Influencing Factors of Oilfield CCUS-EOR Projects under the Dual Carbon Goals

Under the dual carbon goals, carbon capture, utilization and storage combined with enhanced oil recovery (CCUS-EOR) has become an important pathway for petroleum enterprises to coordinate oilfield development and emission reduction. However, the economic feasibility of oilfield CCUS-EOR projects is affected by high capital expenditure, long operation cycles, uncertain oil and carbon prices, CO2 supply costs, transportation distance, reservoir adaptability and monitoring rules. This paper analyzes the economic composition of CCUS-EOR projects from the perspectives of revenue, cost and risk, and identifies the main influencing factors from four dimensions: reservoir engineering, market price, cost investment and policy institution. It further discusses the applicability of discounted cash flow analysis, break-even analysis, sensitivity analysis and uncertainty analysis. The study finds that incremental oil revenue remains the main economic support for most projects, while carbon reduction revenue mainly plays a supplementary and incentive role at the current stage. Improving reservoir screening, source-sink matching, monitoring and verification, carbon market rules and dynamic investment decision-making can enhance project feasibility.
