Using BIB-SEM Imaging for Permeability Prediction in Heterogeneous Shales

Figure 1

BIB-SEM investigation of sample NJ-001 including their local porosity maps and selected areas of interest depicted in Figure 2. All BIB-SEM images were investigated perpendicular to the bedding. The intensity of local porosities is the pore area proportion of each cell illustrated via a log color scale. Pyrites (corresponding to the element S) appear in a bright yellow; silicates (corresponding to Si) are colored green (in this sample: quartz); feldspars (corresponding to Na) are colored pink; carbonates (corresponding to Ca) are colored blue; OM (corresponding to C) is colored black. EDX element maps are illustrated for a rough assessment of possible mineralogical constituents.
