P032 PETROPHYSICAL STUDIES OF SANDSTONES UNDER TRUE-TRIAXIAL STRESS CONDITIONS 1 An innovative polyaxial (true-triaxial) stress-loading system has been developed (King et al. 1995) for conducting petrophysical tests on 50mm-side cubic specimens of rock with the capability of varying two of the principal stresses independently to 115MPa and the third to 750Mpa (Figure 1) with pore pressures limited to 5MPa. It was originally designed to study all nine components (3 P and 6 polarized S) of ultrasonic velocities and attenuation (Figure 2) and directional fluid permeability in the three principal stress directions as oriented sets of fractures were induced in the
