Multifractal Analysis of Reservoir Rock Samples Using 3D X-Ray Micro Computed Tomography Images

Characterizing heterogeneity in reservoir rocks at the pore scale is crucial to understand flow patterns better, and estimate petrophysical properties such as porosity permeability. This study introduces multifractals descriptors for rock samples’ scale. We analyzed twenty samples from sandstone carbonate reservoirs using their 3D X-ray micro-computed tomography images. In addition, we simulated permeability examined correlation with multifractal parameters. The results show that capacity dimension $D_{0}$ information notation="LaTeX">$D_{1}$ correlate images, respectively. Finally, calculated several parameters width of spectrum, asymmetry degree spectrum horizontal direction value vertical difference between two branches spectrum. Results illustrate ability classify groups according heterogeneity.
