CO2 residual trapping coreflooding data

This data set contains the results from CO2/water coreflooding experiments performed on nine sandstone cores. For each core, the 3D porosity, permeability, initial and residual CO2 saturation maps are available. The data shows that the residual trapping ability of sandstone cores is correlated with petrophysical properties such as porosity and the degree of heterogeneity.

Note that the Bentheimer permeability map has unusually high values at the inlet of the core likely due to unexpected experimental artifacts during the drainage experiments. While the center region of the core remains unaffected, the whole core data should be used with extreme caution.

本数据集包含9块砂岩岩心开展CO₂/水岩心驱替实验（coreflooding）所得的实验结果。针对每一块岩心，均可获取其三维孔隙度、渗透率、初始CO₂饱和度及残余CO₂饱和度分布图。实验数据表明，砂岩岩心的残余CO₂捕集能力与孔隙度、非均质性程度等岩石物理性质存在相关性。

请注意，班特海姆（Bentheimer）砂岩岩心的渗透率分布图在岩心入口处出现异常偏高的数值，该现象大概率由排驱实验过程中出现的非预期实验伪迹导致。尽管该岩心的中心区域未受此影响，但使用整块岩心的数据集时仍需格外谨慎。
