Fig. 5

Depth profiles for a in-situ porosity, b in-situ permeability, and c modal pore size distribution. The legend shows the lithology of the core samples. Logging data and porosity data are modified from Inagaki et al. (2012). In-situ porosity and in-situ permeability values were estimated based on the relationship between porosity/permeability and effective pressure, as shown in Fig. 4. The initial permeability plotted in (b) is the measured value at low effective pressure (1 to 3 MPa). The modal pore size was obtained from MICPT measurements under unconfined conditions
