Abstract

MULTICHANNEL PREDICTION ERROR FILTERS (PEF) approximate patterns of primaries and multiples in a least square sense. These filter is time-space variant to handle the multioffset seismic data. PEF for primaries and multiples are estimate from PATTERN MODELS. In an ideal case where accurate PATTERN MODELS of both noise and signal exist, PEF recoveries the primaries while preserving their amplitudes. In more general cases, the pattern model of multiple is obtained by using the data as prediction operator. Application of mentioned PEF on a marine seismic line in one of oil field, demonstrates better results. Consequently, comparison of proposed method with another method of multiples attenuation such as-norm which adaptively subtracts multiples from primaries, illustrates that PEF generally attenuates the multiples and recovers the primaries better.
