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

Description

X-ray micro-CT images of waterflooding in Berea sandstone. The datasets consists of two images: - 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.
