abstract
Deformations, absolute permeability, electrical resistivity, pore volume change, and P-S wave velocities were measured for Berea sandstone under various loading paths at temperatures from 70 degree to 380 degree F. Permeability, electrical resistivity, and strain were recorded in both axial and radial directions for cylindrical samples. Although other studies include some of these measurements, this work is unique in trying to isolate factors which affect rock properties under various loading paths and in both axial and radial directions.
