Stress-Dependent Fluid Flow in a 3D-Printed Rough Fracture

This is the image dataset used in the study of Phillips et al. (2021), containing micro-CT images of single-phase (tagged brine solution with 5 wt. % potassium iodide) fluid flow through a single 3D-printed rough fracture. Data was acquired using a gantry-based micro-CT system, specifically designed for in-situ imaging (UGCT) (Bultreys et al., 2016). Steady-state fluid flow experiments, imaged with a voxel size of 5.76 µm, were undertaken at four different effective stresses (5, 9.2, 12.8 & 13.8 bar) with a constant flow rate of 0.073 mL/min. Further details on the analyses performed on the raw micro-CT images, experimental parameters, and sample properties, can be found in Phillips et al. (2021) and corresponding supporting information. This dataset can be used to investigate the influence of aperture structure on fluid flow under different effective stresses.
