Pore-Scale Dissolution by CO2 Saturated Brine in a Multi-Mineral Carbonate at Reservoir Conditions: Impact of Physical and Chemical Heterogeneity

The datasets contain 40 time-resolved segmented X-ray micro-tomographic images showing mineral dissolution of carbonate rock samples containing dolomite and calcite via CO2 acidified brine fluid flow at reservoir conditions. The tomographic images were acquired at a voxel-resolution of 5.2 µm and time-resolution of 33 minutes. The data were collected with lab based microCT, with an aim of investigating the influences of rock mineral and physical heterogeneity on dissolution patterns and changes to dynamic rock properties at the pore-scale. Further details of the experimental methodology can be found in Al-Khulaifi et al. (2019). These time-resolved tomographic images can be used to validate pore-scale multimineral reactive transport models.

Statement
The details of the sample preparation and fluid injection strategy can be found in Al-Khulaifi et al. (2019). The rock samples were imaged with bench top microCT Versa XRM-500 using a fan beam with photon energies of 50 keV for the initial dry scan of the rock samples and 100 keV for the subsequent wet scans where pore growth due to dissolution is captured. Tomographic images with a size of 20003 voxels were acquired, which were then binned (2×2×2) to obtain images of 10003 voxels with a voxel size of 5.2 ?m. Total acquisition time for each dynamic tomographic image was 33 minutes. The raw grey scale images where filtered using Avizo software NL-means filter (5 5 6), then segmented and processed using Avizo software and converted to The images enclosed are segmented image in 8 bit unsinged .raw format, containing three phases, pore space, dolomite phase and calcite phase.
