High-resolution synchrotron X-ray micro-tomography datasets of multiphase fluid flow in carbonate rocks at reservoir pressure conditions
The datasets contain 416 time-resolved synchrotron X-ray micro-tomographic images (grey-scale and segmented) of multiphase (brine-oil) fluid flow in a carbonate rock sample at reservoir conditions. The tomographic images were acquired at a voxel-resolution of 3.28 µm and time-resolution of 38 s. The data were collected at beamline I13 of Diamond Light Source, U.K., with an aim of investigating pore-scale processes during immiscible fluid displacement under a capillary-controlled flow regime, which lead to the trapping of a non-wetting fluid in a permeable rock. Understanding the pore-scale dynamics is important in many natural and industrial processes such as water infiltration in soils, oil recovery from reservoir rocks, geo-sequestration of supercritical CO2 to address global warming, and subsurface non-aqueous phase liquid contaminant transport. Further details of the sample preparation and fluid injection strategy can be found in Singh et al. (2017). These time-resolved tomographic images can be used for validating various pore-scale displacement models such as direct simulations, pore-network and neural network models, as well as to investigate flow mechanisms related to the displacement and trapping of the non-wetting phase in the pore space.

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 pyrolitic 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 dynamic imaging during imbibition, we collected 800 projections with an exposure time of 0.02 s for each tomographic image. Total acquisition time for each dynamic 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). The images were acquired in .tiff format. These were then processed using Avizo software and converted to .raw format. The greyscale images are in 16 bit unsigned .raw, and binary (segmented) images are in 8 bit unsinged .raw format.
