X-Ray micro-CT data and simulation files for paper 'Representative elementary volumes, hysteresis and heterogeneity in multiphase flow from the pore to continuum scale'

Grant: NE/N016173/1.The data presented herein comprises raw and segmented X-Ray micro-CT data, CMG simulation files and Matlab processing files for the paper 'Representative elementary volumes, hysteresis and heterogeneity in multiphase flow from the pore to continuum scale'. The data is organised as Core 1 and Core 2 respectively. Full core scans are obtained at a resolution of 6 microns. Region of interest (ROI) scans are obtained at 3.45 micron and 2 micon (core 1) and 3.5 micron (core 2). Resolution information is contained within the file names. Voxel sizes in the image files can be changed to match these values. Experimental post-processing files contain the upscaled saturations and porosity values in 3D, which are used in the paper. It also contains the pore-filling analysis. The CMG simulation files contain the input deck, 3D digitial core information (porosity, capillary pressure) needed to simulate both the drainage and imbibition core floods, with corresponding Matlab analysis files. These are Bentheimer outcrop cores obtained from Shell, Amsterdam. It is a shallow marine rock, deposited during the Lower Cretaceous. It outcrops between Enschede and Schoonenbeek in the Netherlands.

本数据集包含了原始及分割的X射线微CT数据、CMG仿真文件以及Matlab处理文件，用于支持论文《从孔隙尺度至连续尺度多相流中的代表性单元体积、滞后效应及异质性》。数据按核心1和核心2分别组织。完整核心扫描以6微米的分辨率进行。感兴趣区域（ROI）扫描分别以3.45微米和2微米（核心1）以及3.5微米（核心2）的分辨率获得。分辨率信息包含在文件名中。图像文件中的体素大小可调整为匹配这些值。实验后处理文件包含了用于论文中的3D放大饱和度和孔隙率值。此外，还包括了孔隙填充分析。CMG仿真文件包含了输入文件、3D数字核心信息（孔隙率、毛细管压力），这些信息用于模拟排驱和吸驱核心洪水，并附有相应的Matlab分析文件。这些数据来源于Shell公司于阿姆斯特丹获得的Bentheimer露头核心。该岩石为浅海沉积，形成于下白垩纪。它出露于荷兰的恩斯赫德和舒嫩比克之间。
