    Abstract: A method for processing seismic data may include receiving input seismic data (di) comprising N spatial coordinates, where the input seismic data is in a first spatial domain, expanding the N spatial coordinates of the input seismic data (di) to N′ modified spatial coordinates, where N′ is greater than N, to provide spatially expanded seismic data (de) that is in a second spatial domain, transforming the spatially expanded seismic data (de) to a model domain to provide model domain data (dm), and generating a final image (df) of a subsurface using the model domain data (dm).

    Abstract: A method for processing seismic data includes receiving seismic data and a velocity model (c(x)) for a plurality of locations (x), scaling a dimension of the seismic data according to the velocity model (c(x)) to provide a velocity normalized seismic data, and generating a final image (S(x)) of the subsurface using the velocity normalized seismic data. The velocity normalized seismic data may be a reverse-time migration image (I(x,ξ)) corresponding to the plurality of locations (x) and a plurality of propagation distance offsets (ξ). The method may also include transforming the reverse-time migration image (I(x,ξ)) for the plurality of selected positions (x) to a wavenumber domain to provide velocity normalized wavenumber data (I(k,ψ)) and suppressing data components corresponding to non-physical or undefined reflection angles to provide enhanced wavenumber data (I′(k,ψ)) and using the enhanced wavenumber data (I′(k,ψ)) to generate the final image (S(x)). A corresponding apparatus is also disclosed herein.

    Abstract: A device, medium and method for de-blending seismic data associated with a subsurface of the earth. The method includes a step of receiving seismic data “d” recorded with one or more land receivers, wherein the seismic data includes shot recordings generated by plural sources that are simultaneously actuated; a step of forming either a continuous receiver trace or trace segments from the received seismic data; a step of selecting plural overlapping spatial blocks that cover the surface shot locations; a step of assigning the shot recordings to the plural overlapping spatial blocks; a step of applying a mathematical technique to the recordings to determine de-blended data; and a step of generating an image of the subsurface based on the de-blended data.

    Abstract: A device, medium and method for deblending seismic data associated with a subsurface of the earth. The method includes receiving an input dataset generated by first and second sources S1 and S2 that are operating as simultaneous sources; arranging the input dataset based on the firing times of source S1; applying with a computing system an annihilation filter to the arranged input dataset to estimate cross-talk noise; convolving the cross-talk noise estimate with an operator to form a signal estimate using the firing times of S1 and S2; and generating an image of the subsurface based on the signal estimate.

    Abstract: Computing device, computer instructions and method for up-down separation of seismic data. The method includes receiving the seismic data, which includes hydrophone data and particle motion data; performing a first up-down separation, which is independent of a ghost model, using as input the hydrophone data and the particle motion data, to obtain first up-down separated data; performing a second up-down separation by using as input a combination of (i) the hydrophone data and/or the particle motion data and (ii) the first up-down separated data, wherein an output of the second up-down separation is second up-down separated data; and generating an image of the subsurface based on the second up-down separated data.
