The micro-CT image data of Bentheimer sandstone used in characterizing its wettability. The primary drainage and imbibition experiments were performed by using air and brine. The images were acquired at irreducible air saturation Sw=94%. This dataset is used to characterize wetting in complex subsurface multiphase systems by using principles of topology and integral geometry.
Segmented images of the inhibition process for a mixed-wet Bentheimer sandstone at different fractional flows at steady state.
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....
