Figure 16.
The image presents four scatter plots arranged in a two by two layout. The top left plot labelled a displays sample average saturation degree against sample average porosity, showing data points in blue for 10 millimetre cubic samples, orange for 20 millimetre cubic samples, and green for 40 millimetre cubic samples. The top right plot labelled b is similar but possibly shows a variation of saturation degree data versus porosity. The bottom left plot labelled c illustrates equivalent gas permeability against sample average porosity, maintaining the same colour coding for sample sizes. The bottom right plot labelled d depicts another equivalent gas permeability versus porosity variation, following the established colour scheme. Each plot features consistent axes with graduated markings, enabling direct comparison of the respective variables across sample sizes.Correlation of sample average porosity (a) with sample average saturation degree and (c) with equivalent gas permeability for different sample sizes under condition HP3D; (b) with sample average saturation degree and (d) with equivalent gas permeability for different sample sizes under condition LP3D
