The field of seismic imaging has made a recent breakthrough in migration technique with the introduction of Joint Migration Inversion to aid the imaging process by incorporating multiple scattering into the algorithm.

In conventional migration process, multiple scattering is removed thus vast amount of energy is wasted that leads to a poor final subsurface image.
