dc.description.abstractDigital rock physics combines modern imaging with advanced numerical simulations to analyze the physical properties of rocks -- In this paper we suggest a special segmentation procedure which is applied to a carbonate rock from Switzerland -- Starting point is a CTscan of a specimen of Hauptmuschelkalk -- The first step applied to the raw image data is a nonlocal mean filter -- We then apply different thresholds to identify pores and solid phases -- Because we are aware of a nonneglectable amount of unresolved microporosity we also define intermediate phases -- Based on this segmentation determine porositydependent values for the pwave velocity and for the permeability -- The porosity measured in the laboratory is then used to compare our numerical data with experimental data -- We observe a good agreement -- Future work includes an analytic validation to the numerical results of the pwave velocity upper bound, employing different filters for the image segmentation and using data with higher resolutioneng

The corresponding CT-image raw-data is taken from Madonna et al. (2013). The voxel size is 0.38m3. Experimental results indicate a porosity of 4.2 \%, a permeability of 4*10-4 mD and a p-wave velocity from 5100 m/s (0 MPa confining pressure) to 6100 m/s (150 MPa confining pressure).} }spa
