  • An eikonal based formulation for HTI media

• Reflection coefficient dependency on media parameters post critical offsets in HTI media

• Forward propagating the recorded data

• Prestack traveltime approximations

• FWI: addressing the nonlinearity once and for all.

• Spectral methods wavefield extrapolation: the residual approach.

• Approximate efficient anisotropic wavefield extrapolation using effective isotropic models.

• PERM: the way to go forward.

• Plenty of FWI, can not catch up in sharing here all of it.

• A lot of machine learning application, follow my group work.
