Fully Controlled Sampling Workflow for Multi-Scale X-Ray Imaging of Complex Reservoir Rock Samples to be Used for Digital Rock Physics, #41840 (2016)

Digital rock physics is a technique to simulate petrophysical properties and fluid flow parameters on digitized rock samples and, as such, requires multi-scale imaging from the pore scale to the plug scale (or core scale). This is straightforward for homogeneous sandstones, which often need only one scale of imaging because the size range of the pore network carrying the flow is very narrow. More heterogeneous rocks such as complex carbonates and tight sands require a sophisticated subsampling strategy including physical drilling, laser ablation, and multiscale X-ray scanning with resolution from several micrometers down to nanometer size.
