Static Mechanical Properties of Mixed Company Sandstone.

Abstract

A number of physical properties of Entrada sandstone were investigated over a range of pressure to 10 kb, room temperature. The sandstone is a massive, very uniform, arkosic sandstone with a grain size close to 0.1 mm and a calcite cement. Porosity of our material ranged from 14% to 24%. The pressure-volumetric strain relation was highly nonlinear and nonrecoverable. The compressional velocity of the sandstone ranged from 2 to 4 km/sec. Relative attention is nearly 50% and is independent of pressure. Electrical resistivity of sandstone is anomalously low when saturated with normal tap water. (Modified author abstract)
