Shot gather data beamer and debeamer

A computer-implemented method for obtaining debeamed data from beamed data, the method comprising:

• receiving beamed data in a third domain, the third domain having at least a first component and a second component, the first component relating to local plane wave arrival time at a beam center surface location of the geophysical volume of interest, and the second component relating to plane wave arrival directions;
• applying a reverse transform to the received beamed data in the third domain to obtain weighted debeamed data in a first domain, the first domain having at least a first component and a second component, the first component relating to seismic wave propagation time within the geophysical volume of interest, and the second component relating to lateral spacing in the geophysical volume of interest;
• transforming the weighted debeamed data from the first domain to a second domain, the second domain having a frequency component and at least one spatial component, the at least one spatial component of the second domain corresponding to the second component of the first domain;
• deweighting the weighted debeamed data in the second domain using a weighting function to obtain deweighted debeamed data;
• and
• obtaining debeamed data in the first domain based on the deweighted debeamed data, the debeamed data associated with shot gather data.

A system configured to obtain beamed data from shot gather data and debeamed data from beamed data, the system comprising:

• one or more processors configured to execute computer program modules, the computer program modules comprising:
• a communications module configured to receive data including one or more of shot gather data for a geophysical volume of interest in a first domain or beamed data in a third domain, the first domain having at least a first component and a second component, the first component of the first domain relating to seismic wave propagation time within the geophysical volume of interest, the second component of the first domain relating to lateral spacing in the geophysical volume of interest, the third domain having at least a first component and a second component, the first component of the third domain relating to local plane wave arrival time at a beam center surface location of the geophysical volume of interest, and the second component of the third domain relating to plane wave arrival directions;
• a time-frequency transform module configured to transform data between the first domain and a second domain, the second domain having a frequency component and at least one spatial component, the at least one spatial component of the second domain corresponding to the second component of the first domain;
• a weighting-deweighting module configured to perform one or more of weighting data using a weighting function or deweighting data using the weighting function;
• a forward-reverse transform module configured to perform one or more of applying a forward transform to weighted shot gather data in the first domain to obtain beamed data in the third domain or applying a reverse transform to beamed data in the third domain to obtain weighted debeamed data in the first domain.
