A method for removing internal multiples from collected data, such as seismic data. The method includes predicting internal multiples for each horizon in a plurality of horizons that created the internal multiples. The internal multiples may be predicted from the seismic data in one pass. After predicting the internal multiples, the method includes creating a separate model of internal multiples for each horizon based on the predicted internal multiples for each horizon. The method then iteratively subtracts each separate model of internal multiples for each horizon from the seismic data.

Attenuating internal multiples from seismic data

Multiple Modeling, wherein the wavefield is separated into up/down wavefield on either source-side or receiver-side; wherein WEMM is used to extrapolate and predict multiples, which are attenuated from OBC seismic data.

Multiple attenuation for ocean-bottom seismic data

Methods for attenuating multiple reflections in seismic data by predicting the multiples using wavefield extrapolation modeling, which uses one-way wavefield propagation in both the up and down directions to predict internal multiples up to a specified order.

Wavefield extrapolation modeling for internal multiple prediction

Embodiments of various technologies for a method for processing seismic data are disclosed. In one embodiment, a first portion of a record of pre-stack seismic data may be displayed in a three-dimensional XYZ (3-D XYZ) space. A selection may be received of a second portion of the record of the pre-stack seismic data within the first portion. One or more attributes may be determined that define the second portion. One or more regions may be identified within the record of the pre-stack seismic data having the attributes that define the second portion.

A method for spectrally conditioning surface seismic data. In one implementation, the method may include correcting surface seismic data for distortions due to anomalous spectral amplitudes, thereby generating a first set of corrected data; correcting the first set of corrected data for deterministic distortions, thereby generating a second set of corrected data; correcting the second set of corrected data for spectral distortions due to the seismic waves traveling through the near-surface, thereby generating a third set of corrected data; and correcting the third set of corrected data for spectral distortions due to the seismic waves traveling through deeper strata.
