Experimental Investigation of the Dependence of Accessible Porosity and Methane Sorption Capacity of Carbonaceous Shales on Particle Size

<div>“Apparent porosity” calculated as a function of time during pressure equilibration in He pycnometry measurements for samples investigated in this study (dots) and additional samples (lines) studied previously. Equilibrium and differential pressures were &lt;1 MPa.</div>
