Table T1 summarizes the effective stress and estimated porosity and permeability at each consolidation step as well as the grain size distribution for selected samples. Measured vertical permeabilities vary from 5.4 × 10–19 m2 to 1.3 × 10–15 m2. All samples were dominated by clay-sized particles, ranging between 53 and 77 wt%. The secondary grain size for all samples were silt-sized particles, ranging between 22 and 41 wt%. Sand-sized particles make up the smallest grain size fraction, ranging between 1 and 19 wt%.
