Computation of effective elastic properties from digital images without segmentation
Nicola Tisato, Kyle T Spikes · 2016
In the last few years, Digital Rock Physics (DRP) has become an avenue to investigate effective properties of geomaterials. In particular, the physical properties of samples imaged using micro-computed tomography (μCT) are estimated through segmentation of the μCT dataset. Nevertheless, segmentation proves to be a challenging and arbitrary procedure that might lead to inaccurate estimates of physical properties. Here we propose a new technique to extract elastic properties from a μCT dataset without the use of segmentation, thus improving accuracy and easing the overall workflow. The proposed method takes advantage of effective medium theories and uses the density and the porosity, which are measured in the laboratory, to constrain the final result.
