The procedure to construct the migration image using the computation of Gaussian beams with anisotropy for difficult-arranged subsurfaces gives a more accurate picture than the widely used Kirchhoff migration.
The correct description of the wave propagation process makes it possible to restore the pre-salt image with a good resolution and a high ratio signal/noise.
The requirements posed to the developers:
- The necessity of taking into account the anisotropy in the migration data.
- Acquisition of subsalt thicknesses
- Applying many data component.
- Time-sensitive calculations.
- True amplitudes.
