Abstract
Internal multiple attenuation presents a major problem to both the geologist and the geophysicist. For the first the amount of noise can often be such that accurate interpretation of the primary seismic wavefield is impossible making seismic data unusable. For the second, internal multiples are hard to distinguish in the total wavefiled, and the problem is more difficult to deal with than with surface related multiple. Internal multiples have a dispersed character that creates a curtain of noise often stronger than primaries where move out discrimination or deconvolution techniques fail.
