Abstract
During the early screening phase of Carbon Capture and Storage (CCS) site evaluations limited time and data are available and hence CO2 plume evaluations using time and data intensive reservoir simulations are almost never performed. However, there is still a need for early plume evaluations to risk and rank injection sites relative to each other. Therefore, an alternative fluid migration method called invasion percolation is adopted for the CCS screening phase to predict the extent and location of CO2 plumes in the subsurface. Invasion percolation as part of basin modeling is a rapid method, which requires limited data and is ideal for the early screening phase. Invasion percolation results are compared to uncalibrated reservoir models, typical for the screening phase, revealing that plume location shape and size are very reasonable especially when compared to seismic observed plume outlines. It can be concluded that invasion percolation as part of basin modeling is a fit for purpose method, which can assess multiple opportunities rapidly during the early intake screening phase to risk and rank opportunities relative to each other and to build a CCS injection site portfolio. In addition to the plume evaluation, basin models can provide useful basin-scale or injection site specific pressure and temperature predictions as well as CO2 density estimates for static volume calculations before detailed reservoir and stratigraphic models are available. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
用于二氧化碳捕获和封存场地筛选和特征描述的侵蚀渗流和盆地建模
在碳捕获与封存(CCS)场地评估的早期筛选阶段,由于时间和数据有限,因此几乎从未使用时间和数据密集型储层模拟来进行二氧化碳羽流评估。然而,仍有必要进行早期羽流评估,以便对注入地点进行风险排序。因此,在二氧化碳捕获与封存(CCS)筛选阶段采用了另一种流体迁移方法--入侵渗流法,以预测地下二氧化碳羽流的范围和位置。作为盆地建模的一部分,入侵渗流法是一种快速方法,需要的数据有限,非常适合早期筛选阶段。入侵渗流结果与筛选阶段典型的未校准储层模型进行了比较,发现羽流位置的形状和大小非常合理,尤其是与地震观测到的羽流轮廓相比。可以得出的结论是,作为盆地建模的一部分,入侵渗流是一种适用的方法,可以在早期摄入筛选阶段快速评估多个机会,对机会进行风险排序,并建立 CCS 注入地点组合。除了羽流评估之外,盆地模型还可以在获得详细的储层和地层模型之前,提供有用的盆地尺度或注入地点特定的压力和温度预测,以及用于静态体积计算的二氧化碳密度估算。© 2024 化学工业协会和 John Wiley & Sons, Ltd. 保留所有权利。
