Statement

The details of the sample preparation and fluid injection strategy can be found in Singh et al. (2017). The rock sample was imaged with synchrotron X-ray micro-tomography at the Diamond Light Source (UK), on the Diamond-Manchester Imaging Branchline (I13-2), using a pink beam with photon energies up to 30 keV. The low energy X-rays were filtered by placing a set of 0.2 mm pyrolytic carbon, 2.2 mm aluminum, and 0.1 mm gold filters in the beam, which controlled the heating of the sample due to the absorption of low energy X-rays by the sample. The X-rays were converted to visible light by using a 250 ƒÊm thick CdWO4 scintillator; these photons were then recorded by a PCO Edge camera. Tomographic images with a size of 20003 voxels were acquired at a voxel size of 1.64 ƒÊm, which were then binned (2~2~2) to obtain images of 10003 voxels with a voxel size of 3.28 ƒÊm. A total of 3000 projections with an exposure time of 0.06 s were acquired over 180‹ rotation for scanning the dry rock sample before starting the flow experiment. For time-resolved imaging during drainage and imbibition, we collected 800 projections with an exposure time of 0.02 s for each tomographic image. Total acquisition time for each time-resolved tomographic image was 24 s (16 s for acquisition and 8 s for triggering). The real time-step between each image was 38 s (which included 14 s for repositioning the rotation stage and transferring the data to a storage disk). We acquired a total of 496 tomographic images during drainage and 416 images during imbibition. The images were acquired in .tiff format. These were then processed using Avizo software and converted to .raw format. The grey-scale images are in 16 bit unsigned .raw, and binary (segmented) images are in 8 bit unsinged .raw format.
