Abstract: Method for reconstructing seismic data. The method includes receiving at a computing device an input seismic data set d related to plural shots emitted by one or more seismic sources; receiving at the computing device a positional data set dp relating to recording locations of the receivers that recorded the input seismic data set d; receiving at the computing device a receiver target location; calculating an adjusted receiver location based on (i) the positional data set dp and (ii) the receiver target location, wherein the adjusted receiver location substantially coincides with a receiver location from the positional data set dp; calculating reconstructed seismic data dr at the adjusted receiver location using the input seismic data set d and the positional data set dp; and correcting the seismic wave paths from the one or more seismic sources to the receivers based on the reconstructed seismic data dr.

Abstract: A method for estimating a time variant signal representing a seismic source obtains seismic data recorded by at least one receiver and generated by the seismic source, the recorded seismic data comprising direct arrivals and derives the time variant signal using an operator that relates the time variant signal to the acquired seismic data, the operator constrained such that the time variant signal is sparse in time.

Abstract: Methods and systems for processing data acquired using a variable-depth streamer, obtain up-going and down-going wavefields at a predetermined datum, and use them to identify multiples included in the up-going wavefield. An image of a geological formation under the seabed is then generated using the data from which the multiples have been removed, and/or the multiples.

Abstract: Computing device, computer instructions and method for deghosting seismic data related to a subsurface of a body of water. The method may include receiving input seismic data recorded by seismic receivers that located at different depths (zr), generating migration data (du) and mirror migration data (dd) from the input seismic data, deriving a ghost free model (m) based on simultaneously using the migration data (du) and mirror migration data (dd), generating primary (p) and ghost (g) datasets based on the ghost free model (m), simultaneously adaptively subtracting the primary (p) and ghost (g) datasets from the migration data (du) to provide adapted primary (p′1 and p′2) and adapted residual (r′1 and r′2) datasets and generating a final image (f) of the subsurface based on the adapted primary (p′1 and p′2) and the adapted residual (r′1 and r′2) datasets.

Abstract: A method for generating an image of a subsurface based on blended seismic data includes receiving the blended seismic data, which is recorded so that plural traces have uncontaminated parts with different uncontaminated recording time lengths, selecting plural subgroups (SG1, SG2) of traces so that each subgroup (SG1) includes only uncontaminated parts that have a same uncontaminated recording time length, processing the traces from each subgroup to generate processed traces, mapping the processed traces to a same sampling, combining the processed traces from the plural subgroups (SG1, SG2) to generate combined processed traces, and generating an image of a structure of the subsurface based on the combined processed traces.

Abstract: Computing device, computer instructions and method process input seismic data d recorded in a first domain by seismic receivers that travel in water, the input seismic data d including pressure and particle motion measurements, including up-going and down-going wave-fields. A model p is generated in a second domain by solving an inverse problem for the input seismic data d, wherein applying an L transform to the model p describes the input data d. An L′ transform, which is different from the L transform, is then applied to the model p to obtain an output seismic data in the first domain, the output seismic data having a characteristic imparted by the transform L′. The characteristic is related to pressure wave-fields and/or particle motion wave-fields interpolated at positions in-between the input seismic receivers. An image of the surveyed subsurface is generated based on the output seismic dataset.

Abstract: There is a method for correcting seismic wave propagation paths through the earth. The method includes determining a first fixed shooting sequence for a first bandlimited seismic source; determining a second shooting sequence for a second bandlimited seismic source, wherein the second shooting sequence includes second shooting positions that correspond to second energy emissions, and the second energy emissions differ from the first energy emissions in at least one of an emission time, phase and amplitude; receiving raw seismic data recorded with seismic receivers and generated as a result of the first and second energy emissions, wherein the raw seismic data is indicative of seismic wave paths from the first and second bandlimited seismic sources to the seismic receivers; separating the raw seismic data into a first bandlimited set corresponding to the first bandlimited seismic source and a second bandlimited set corresponding to the second bandlimited seismic source; and correcting the seismic wave paths, from the first and second bandlimited seismic sources to the seismic receivers, based on at least one of the first and second bandlimited sets.

Abstract: Computing device, computer instructions and method for processing energy at a free-surface reflection relating to an air-water interface. The method includes receiving input seismic data recorded with seismic sensors; receiving wave-height data that describes an actual shape of a top surface of a body of water; processing up-going energy at a receiver and down-going energy following a reflection at the sea-surface, using the input seismic data and a linear operator modified to take into account the wave-height data; and generating an image of the subsurface based on the up-going energy or the down-going energy or a combination of the input seismic data and one of the up-going or down-going energy.

Abstract: During seismic data acquisition the seismic sources and/or seismic receivers are deployed according to an irregular arrangement departing in a predetermined manner from repetitive spatial patterns formed by or within groups of adjacent among the seismic sources or adjacent among the receivers. Additionally or alternatively, source activation moments of the sources within a series of source firing time intervals are determined using Golomb ruler sequences or a non-linear inversion.
