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.
