Digital rock physics (DRP) is used to estimate physical properties of rocks by means digital models. Conventional requires very high resolution images, as grains and pores need be well resolved in order assign each voxel the an endmember. Using targeted method, which does not require segmentation, voxels that capture a mixture pore grain are assigned effective medium theory. The therefore, resolving individual boundaries, lower scanning possible. Here we show results segmentation-less DRP where four Berea sandstone samples were scanned with at 40 microns per voxel, two also 60 80 voxel. Density, porosity elastic estimated for scan, then compared laboratory measurements. At first order, multiple resolutions no obvious effect on property estimation low scans computationally efficient, accuracy was compromised. This abstract provides further validation methodology.
