- •
Type III kerogens poorly develop the organic pores produced by hydrocarbon-generation.
- •
Clay-hosted pores dominate the pore system of Shanxi Shale and determine the PSD.
- •
The ‘closed area’ of hysteresis loop is applicable to predict the PSD.
- •
Different clay mineral types possess different characteristic pore-sizes.
