Using BIB-SEM Imaging for Permeability Prediction in Heterogeneous Shales

Figure 4

BIB-SEM investigation of sample NJ-019 including their local porosity maps and selected areas of interest depicted in Figure 6. Pyrites (corresponding to the element S) appear in a bright yellow; silicates (corresponding to Si) are colored green (in this sample assumed to represent K-containing feldspar grains); Na-feldspars (corresponding to Na) are colored pink; carbonates (corresponding to Ca) are colored blue; OM (corresponding to C) is colored black.
