The reduced elastic wave equations are derived from the ab initio 1st-order full elastic wave equations with clear definitions of stress variables and assumptions. The derived equations are valid for both isotropic and transversely isotropic (TI) medium...

This pave the way for the application of other self-supervised procedures to seismic data that go beyond the assumption...
