Imaging the subsurface where seismic illumination is poor is a difficult exercise. Conventional imaging techniques such as migration are insufficient. Better results can be obtained from regularized least-squares inversion methods that use migration operators in a conjugate-gradient minimization. We demonstrate this regularized inversion using downward continuation migration and regularization along offset ray parameters (reflection angles) on a real 2-D seismic line. The result is cleaner than the migration result and has filled in some amplitude information where poor illumination caused gaps. We discuss a regularized inversion that uses common azimuth migration and the same type of regularization to image a real 3-D subsurface around a salt body.
