Fig. 5: Decane-saturated pore size distribution.
From: Reduced methane recovery at high pressure due to methane trapping in shale nanopores

Size distribution fitting shows that increased intensity in high Q for the 6000 psi peak pressure case is caused by scatterers <1 nm in radius. The solid black line showed the ambient size distribution and dashed red line shows the distribution at 6000 psi.
