“…Porosimetry curves were measured with a Quantachrome Autoscan 60 having a pressure range of 15 to 60,000 psi, corresponding to pore radii of 7.1 to 0.0018 micrometers. The instrument utilized a continuous pressure ramp, rather than discrete pressure jumps, to minimize pressure lags (Winslow, 1984). Large chips of shale, 5-10 mm diameter, were used to minimize low pressure intrusion due to surface irregularities and pores (Borst, 1982).…”

Abstract--The extent of illite/smectite (I/S) reactions is linked with quantitative measurements of shale fabric in a suite of samples from a lower Frio Formation well. Greater illitization of the I/S clays is found in laminated shales that possess a larger pore surface area/pore volume (SA/V) of 3.21 x 106 cm-~ than the adjacent massive shale lithofacies with a SA/V of 1.97 x 106 cm -~. Mean pore diameter in both shale lithologies is 0.0145 micrometers, though in the laminated shale distributions are skewed towards more smaller-sized pores. While no direct permeability measurements were made, estimates of permeability that are based on simple physical models using SA/V suggest that lower permeabilities are associated with laminated shales. The trend of greater illitization at higher SA/V values is contrary to expectations that reaction extent is enhanced by greater permeabilities, such as created by silt laminations in shale. The limitations of estimated permeabilities emphasize that porosimetry measurements of shale fabric are useful for estimating the access of material to all reaction sites, and do not just describe the effect of a few large pores that dominate permeability. Greater reaction extent in the laminated shales is associated with the accessibility of fluids to more pore space than in the massive shales.

“…This can be used as a model of the process of mercury intrusion into a sample of porous material that takes place in the mercury porosimeters. This enables an analytical expression for the so-called capillary potential curve of porous sample directly obtained from mercury intrusion data, [22,23], to be derived. Description of such curves is necessary for interpretation of mercury porosimetry data.…”

“…The modeling of quasi-static processes of non-wetting liquid intrusion into porous material plays an important role in the interpretation of experimental data (the so-called capillary potential curves) for mercury porosimetry obtained by mercury intrusion into a sample of porous material [22,23]. The parameters of the pore space structure, that is, the porosity and pore size distribution, the specific pore surface area and its distribution [14,17,18,23] and the tortuosity and permeability [2,9,21] are determined from these data.…”

This paper proposes a continuum description of the quasi-static processes of non-wetting liquid intrusion into a porous body. The description of such processes is important in the interpretation of mercury porosimetry data, which is commonly used to determine the pore space structure parameters of porous materials. A new macroscopic model of capillary transport of non-wetting liquid in porous material is proposed. It is assumed that a quasi-static process of liquid intrusion takes place in the pore space-pressure continuum and that liquid filling an undeformable porous material forms a macroscopic continuum constituted by a mobile and a capillary liquid which exchange mass and energy. The capillary liquid forms a thin layer on the surface of the liquid filling the porous material that is in contact with the internal surface of the pores. It is immoveable and contains the whole capillary energy. Mass balance equations for both constituents and constitutive relations describing capillary transport in the pore space-pressure continuum are formulated, and a boundary condition on the surface of the porous body is proposed. The equations obtained are solved for the special case of liquid intrusion into a ball of porous material. Analytical expressions are obtained for the saturation distribution of non-wetting liquid in the ball and for the capillary potential curve. Their dependence on parameters of the system is analyzed.
