Abstract: Methods and devices for seismic data processing deblend seismic data gathered using simultaneous source acquisition by applying two different deblending techniques. The second deblending technique is applied to residual data obtained after applying the first deblending technique. At least one of these first and second deblending techniques uses a signal-to-noise map.

Abstract: A device, medium and method for processing seismic data associated with a subsurface of the earth. The method includes a step of receiving seismic data (d) recorded with one or more seismic receivers; a step of processing the seismic data (d) with a first processing algorithm to obtain imaged seismic data (D); a step of constructing wave-fields (W) corresponding to the imaged seismic data (D) by solving a given wave equation, wherein the wave-fields (W) have an added axis (τ) which maps back spectral properties of the imaged seismic data to its pre-imaging state; and a step of processing the wave-fields (W) along the axis (τ) with a second processing algorithm.

Abstract: A non-blended dataset related to a same surveyed area as a blended dataset is used to deblend the blended dataset. The non-blended dataset may be used to calculate a model dataset emulating the blended dataset, or may be transformed in a model domain and used to derive sparseness weights, model domain masking, scaling or shaping functions used to deblend the blended dataset.

The 4D difference (Δij) is minimized.
