Water-wet three-phase flow micro-CT tomograms

This dataset contains 3D images of a Ketton water-wet rock saturated with two or three phases (KI-doped brine, iododecane-doped decane and nitrogen). The images were obtained at two different resolutions (5 and 2 micrometres per voxel side) using a laboratory based X-ray micro-CT scanner. We provide raw data after each of the following injection steps: - dry image - oil injection in a fully brine saturated sample (OI) - first waterflooding (WF1) - gas injection (GI) - second waterflooding (WF2) Due to the use of some dopants, the attenuation order of the phases to X-rays is the following, from least attenuating (darkest) to most attenuating (brightest) ones: 1) gas 2) brine 3) rock 4) oil
