Estimation of CO2 Practical Capacity in Saline Formations

摘要

Based on the Techno-Economic Resource-Reserve Pyramid, CO2 storage capacity is divided to Theoretical Capacity, Effective Capacity, Practical Capacity, and Matched Capacity. These different classes consider the data sufficiency on geology, engineering, economics, and CO2 sources, respectively. Practical Capacity is important for a mature CCS project. The purpose of this study was to propose a procedure for estimating Practical Capacity. A case study focusing on estimations of Practical Capacity was presented and discussed. Combining simulation runs and economic analysis, the values of Practical Capacity were evaluated. We found that there is a linear relationship between Practical Capacity and net present value (NPV). The relationship is useful for determining the optimal operation scenario when the best Practical Capacity or NPV is considered.
