Abstract: Determination of transport phenomena properties in porous media is one major objective of core analysis studies in petrophysics, reservoir engineering, and groundwater hydrology. Porosity measurement may be considered as a key factor to identify the hydraulic performance of a low permeable porous medium (e.g. rock or concrete). Additionally, the rate of absorption under pressure depends on the permeability, which is related to the connectivity between the existing pores within the porous structure. An alternative Gas Expansion Induced Water Intrusion Porosimetry (GEIWIP) method and apparatus is useful to measure the total porosity and pore size distribution, using a gas/water intrusion apparatus for water tight materials.
