Figure 15: Fractured Madison Limestone cluster analysis at threshold values: (A) 0.35 (A), and (B) 0.60 that correspond to the cluster valleys found in Figure 14.
Porosities calculated following the workflow and used for the cluster analysis are shown in Table 3. These porosities are comparable to the measured gravimetric porosities. Berea Sandstone has a percent error of 8.1%, while Indiana and Madison limestone have percent errors of 14.8% and 4.2%.
