Abstract

Measurements of dynamic properties of rock at high temperatures and pressures have many applications to geology and solid earth geophysics. Elastic wave velocities are obtained from rock cylinders in which delay times are measured using a pulse transmission technique. The longitudinal and shear velocities and bulk densities allow the calculation of isotropic elastic moduli. Techniques and equipment used for measuring velocities as functions of confining pressure, pore pressure, and temperature are summarized.
