Paper Summary
One of the fundamental challenges for anisotropic tomography is the trade-off between the inverted velocity correction and the anisotropic parameters correction. The studies in this paper find that the conventional tomography solution is not sufficient to resolve the updates in velocity and in the anisotropic parameters. The tomography solver needs to be modified to include additional precondition, such as geological and well constraints for inversion, in order to reduce the uncertainties and provide geologically consistent anisotropic models.
