Abstract EN
A transversely isotropic (TI) model in which the tilt is constrained to be normal to the dip (DTI model) allows for simplifications in the imaging and velocity model building efforts as compared to a general TI (TTI) model.
Although this model cannot be represented physically in all situations, for example, in the case of conflicting dips, it handles arbitrary reflector orientations under the assumption of symmetry axis normal to the dip.
Using this assumption, we obtain efficient downward continuation algorithms compared to the general TTI ones, by utilizing the reflection features of such a model.
Phase-shift migration can be easily extended to approximately handle lateral inhomogeneity using, for example, the split-step approach.
This is possible because, unlike the general TTI case, the DTI model reduces to VTI for zero dip.
These features enable a process in which we can extract velocity information by including tools that expose inaccuracies in the velocity model in the downward continuation process.
We test this model on synthetic data corresponding to a general TTI medium and show its resilience.
