Title: Pore Structure in Sandstones by Compressible Sphere-Pack Models

Author(s): I. Fatt (2)


Porosity and flow measurements made on packs of rubber spheres under compression indicate that ideal sphere packs do not model the flow properties of consolidated sandstones. Packs of rubber cubes have plate-like pore spaces. Under compression brine-saturated packs of rubber cubes display the same rapid increase in electrical conductivity observed when brine-saturated sandstones are compressed. This observation leads to the hypothesis that pore spaces in consolidated sandstones are plate-like, that is, they have two large and one small dimension. Compression of consolidated sandstone causes collapse of these plate-like pores.
