Summary
A joint PP-PS inversion methodology is extended to use pure S-wave (SS) data. All three seismic wave modes are jointly inverted in their native time domain and their corresponding time axes are dynamically updated during the inversion through the optimization of the P-to-S velocity ratio. The benefits of including PS and SS data in addition to PP data for seismic reservoir characterization through elastic inversion are illustrated on a synthetic dataset.
