In an effort to reduce carbon dioxide (CO2) emissions from large stationary sources, carbon capture and storage (CCS) is being investigated as one approach in a portfolio of greenhouse gas (GHG) reduction strategies. This work assesses CO2 storage rates and efficiency of saline formations classified by interpreted depositional environment at the regional scale over a 100-year time frame. The focus of this study was placed on developing results applicable to future commercial-scale CO2 storage operations in which an array of injection wells would be used to optimize storage in saline formations. The results of this work suggest future investigations of prospective storage resource in closed or semiclosed formations that may focus less heavily on interpretation of depositional processes. However, the results illustrate the relative importance of depositional environment, aquifer depth, structural geometry, and boundary conditions on the rate of CO2 storage in closed or semiclosed systems.

量化沉积环境对深层盐水形成CO2储存效率和速率的影响

为了减少来自大型固定源的二氧化碳(CO 2)排放,正在研究碳捕集与封存(CCS)作为温室气体(GHG)减排策略组合中的一种方法。这项工作评估了在100年的时间范围内,按区域规模解释的沉积环境对CO 2的封存率和盐分形成的效率进行了评估。这项研究的重点放在开发适用于未来商业规模CO 2的结果上储存操作,其中将使用一系列注入井来优化盐水层中的储存。这项工作的结果表明,未来对封闭或半封闭地层中潜在储层资源的研究可能不太集中于沉积过程的解释。但是,这些结果说明了封闭环境或半封闭系统中沉积环境,含水层深度,结构几何形状和边界条件对CO 2储存速率的相对重要性。
