Anisotropic Reflection and Transmission Joint Tomography - Method and Interests

Ignoring anisotropy in tomography leads to inaccurate distorted velocity fields and depth migrated images. However reflected data are known to not be able to constrain anisotropic parameters. Additional information is necessary. We do present an extension to anisotropy of a joint transmitted and reflected tomography based on locally coherent events. The application of the joint slope tomography to synthetic examples shows how borehole transmitted data significantly improve well-tie and refine velocity models coming from isotropic reflection tomography.
