ABSTRACT

Stolt residual migration (SRM) is an effective technique for image processing after migration. It allows us to reconstruct an image corresponding to a velocity different from the original migration velocity. Furthermore, multiple attenuation in the image space (MAIS) is a powerful technique for seismic data processing after migration. Combining these two techniques makes it possible to remove multiples in the image space without accurately knowing the velocity model. The PZ section of the Mahogany field serves as a field data example to demonstrate the advantage of this combined methodology.
