Abstract: Methods and systems for target oriented 4D binning of seismic data are presented. A target depth horizon is selected in the vicinity of where 4D changes are expected. Respectively for each data vintage, relationships between the seismic traces and reflection bins, associated with the depth surface, are established and the seismic traces are divided into common reflection angle subsets. The best matching traces from both vintages are selected for each reflection bin and output for further processing.

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.

Abstract: During a seismic survey, shots located close to one another are fired at a time interval shorter than an echo time interval and longer than a closest receiver time interval. During the echo time interval which follows a first shot, receivers located within a predetermined distance from the first shot location detect seismic reflections related to the first shot. During the closest-receiver time interval which follows the first shot, at least one seismic receiver located closest to the first shot location detects all the reflections from the first shot reaching this seismic receiver.

Abstract: A method for spectral analysis of seismic data obtains imaged seismic data and generates orthogonally shifted imaged seismic data gathers. The orthogonally shifted imaged seismic data gathers are processed to generate a spectrally processed imaged seismic data. Alternatively, the imaged seismic data are obtained using a spectral processing filter that is a function of a magnitude of a total wavenumber of the imaged seismic data in three dimensions and a spatially variable velocity function.

Abstract: Recorded seismic data are obtained at a plurality of receivers from a plurality of sources, and a set of sources from the plurality of sources is selected using spatial criteria based on a location of each source such that any two sources in the set of sources are separated by a predefined minimum distance of separation sufficient to reduce cross talk between sources. The set of sources is combined in a non-encoded manner into a composite source, and forward modeling for the composite source is performed to generate a synthetic seismic data set. A composite recorded seismic data set for the set of sources is determined, and the synthetic seismic data set and composite recorded seismic data set are used to determine a residual seismic data set. Backward modeling generates a gradient update used to generate an updated earth model.
