Figure 19.
The image presents two graphs side by side. The left graph depicts cumulative probability on the vertical axis against sample average saturation degree on the horizontal axis, ranging from 0.7 to 1. The right graph shows cumulative probability on the vertical axis against equivalent gas permeability on the horizontal axis, from 0 to 1.2 times 10 to the power of negative 19 square metres. Each graph includes multiple curves distinguished by colour and line style, indicating different experimental conditions based on various dimensional configurations, 2 D and 3 D arrangements, including specific measurements for each configuration. The legend explains the corresponding curves for clarity.Cumulative distribution of (a) sample average saturation degree and (b) equivalent gas permeability for different sample sizes under conditions HP2D and HP3D
