WebMultiple variable regression models will also be analyzed to estimate these properties, that is, using porosity and apparent density in the same equation, instead of separately. It is worth noting that the porosity was obtained through the analysis of porosimetry by mercury intrusion. EXPERIMENTAL Materials WebSeveral methods can be employed to directly measure rock porosity: (1) saturation or imbibition, (2) buoyancy, (3) gas expansion (He porosimetry), (4) gas adsorption (BET) and (5) mercury intrusion porosimetry (e.g., Tiab and Donaldson 2004; Sondergeld et al. 2010; Clarkson et al. 2012c ).
