Overburden Acoustic Velocity System

System function. Measures P- and S-wave velocities through a rock specimen held under controlled axial (overburden) stress.

Controlled. Axial/overburden stress; ultrasonic pulse.

Measured / reported. P- and S-wave transit times and velocities versus stress; dynamic moduli.

Configuration. Stress range and transducers configured per project.

Reference guidance; configurable per project.
