FIB-SEM and X-ray micro-tomographic images of carbonate rock dissolution during reactive CO2-saturated brine injection under reservoir conditions
Dataset description
The datasets contain FIB-SEM and X-ray micro-tomographic images of a wettability-altered carbonate rock sample before and after dissolution with reactive CO2-saturated brine at reservoir pressure and temperature conditions. The data were acquired with the aim of investigating CO2 storage in depleted oil fields that have oil-wet or mixed-wet conditions. Our novel procedure of injecting oil after reactive transport has revealed previously unidentified (ghost) regions of partially-dissolved rock grains that were difficult to identify in X-ray tomographic images after dissolution from single fluid phase experiments. The details of image files and imaging parameters are described in readme file.

| Lineage statement | The experiments were conducted on a 3.8 mm diameter and 13.3 mm long Ketton limestone rock sample from the Ketton quarry, Ruthland, U.K., which contains >99% calcite. The rock sample was imaged before fluid injection (dry scans), after dissolution and sequential injection of oil and brine at a voxel size of 2 μm, using a Zeiss Xradia 500 Versa X-ray micro-tomography scanner with 80 kV and 7 W settings. Two images were acquired at a distance of ~9.5 mm and ~3.5 mm from the base of the sample respectively. A total of 4000 projections were acquired for each tomographic image. We also conducted the FIB-SEM analysis at two different locations (control and partially dissolved) using an FEI Quanta 3D DualBeam FIB-SEM scanner. |
