Berea sandstone: X-ray micro-CT imaging of waterflooding in a water-wet and a mixed-wet sample

X-ray micro-CT images of waterflooding in Berea sandstone. The datasets consists of two imaged datasets:
- segmented water-wet sample (Berea_Unaltered_waterflooding_segmented)
- segmented mixed-wet sample (Berea_Altered_waterflooding_segmented)

The images were segmented into six phases: clay minerals; quartz-feldspar minerals; cemented calcite; others highly X-ray attenuating minerals; brine phase; oil phase.

These images have been employed to investigate the role of mineralogy in controlling rock wetting state in oil-brine systems. For additional information, please refer to Garfi et al. (2019):

Berea砂岩水驱过程的X射线显微CT（X-ray micro-CT）图像数据集。本数据集包含两组成像样本：
- 经分割的水湿岩心样本（Berea_Unaltered_waterflooding_segmented）
- 经分割的混合湿岩心样本（Berea_Altered_waterflooding_segmented）

所有图像已被分割为六类物相：黏土矿物、石英-长石类矿物、胶结方解石、其他高X射线衰减矿物、盐水相以及油相。

该数据集已被用于探究矿物学特征对油-盐水体系中岩石润湿性的调控作用。如需获取更多相关信息，请参考Garfi等人（2019）的研究成果：
