High resolution elastic imaging of laboratory rock/core samples can provide valuable information about the quantitative small-scale physio-chemical changes including stress changes and fluid flow. We present the application of 3D Full Waveform Inversion (a high resolution imaging technique) to a laboratory acoustic data that we acquired with high spatial ultrasound source-receiver distribution.
