为了减轻 气候变化。实现这种减少的方法之一是捕获和储存二氧化碳。 （CCS）。CCS要求在大型工业设施中捕获二氧化碳（CO2）， 例如发电厂，以及向CO2所在的地质储存场地的运输 被隔离的如果实施，CCS可以允许化石燃料使用很少或没有二氧化碳 直到替代能源得到更广泛的应用。大量 CO2最有效地通过管道输送并储存在深盐水层中。 或在油藏中，其中CO2用于提高石油采收率（EOR）。本论文 描述一组用于估算CO2项目特定成本的模型 运输和储存。管道CO2输送的工程经济模型 洪水提高采收率和蓄水层就是为此而开发的。这些模型结合在一起 概率分析能力，用于量化运输的敏感性和 存储成本对模型输入参数的可变性和不确定性的影响。二氧化碳的成本 除了 管道的长度和设计能力等因素。在 盐渍含水层对影响场地特征成本的因素最为敏感。 对于提高采收率项目，CO2储存历来是采油的次要影响； 因此，无法确定CO2储存的平衡成本。相反，EOR项目是 基于CO2的盈亏平衡价格（即，项目所在的CO2价格）进行评估 净现值为零)。CO2收支平衡价格对石油最为敏感。 油价、油藏生产区外CO2的损失以及油藏压力。 未来的研究应该包括收集和聚集更具体的数据 3.表征含水层储存的可能地点以及这些模型的应用 数据。替代性法规和现场要求的含义 还应研究表征以更全面地评估成本影响。

Large reductions in carbon dioxide (CO2) emissions are needed to mitigate the impacts of climate change. One method of achieving such reductions is CO2 capture and storage (CCS). CCS requires the capture of carbon dioxide (CO2) at a large industrial facility, such as a power plant, and its transport to a geological storage site where CO2 is sequestered. If implemented, CCS could allow fossil fuels to be used with little or no CO2 emissions until alternative energy sources are more widely deployed. Large volumes of CO2 are most efficiently transported by pipeline and stored either in deep saline aquifers or in oil reservoirs, where CO2 is used for enhanced oil recovery (EOR). This thesis describes a suite of models developed to estimate the project-specific cost of CO2 transport and storage. Engineering-economic models of pipeline CO2 transport, CO2- flood EOR, and aquifer storage were developed for this purpose. The models incorporate a probabilistic analysis capability that is used to quantify the sensitivity of transport and storage cost to variability and uncertainty in the model input parameters. The cost of CO2 pipeline transport is shown to be sensitive to the region of construction, in addition to factors such as the length and design capacity of the pipeline. The cost of CO2 storage in saline aquifers is shown to be most sensitive to factors affecting site characterization cost. For EOR projects, CO2 storage has traditionally been a secondary effect of oil recovery; thus, a levelized cost of CO2 storage cannot be defined. Instead EOR projects were evaluated based on the breakeven price of CO2 (i.e., the price of CO2 at which the project net present value is zero). The breakeven CO2 price is shown to be most sensitive to oil prices, losses of CO2 outside the productive zone of the reservoir, and reservoir pressure. Future research should include collection and aggregation of more specific data iiicharacterizing possible sites for aquifer storage and applications of these models to this data. The implications of alternative regulations and requirements for site characterization should also be studied to more fully assess cost impacts.
