Abstract

A method for processing seismic data. The method may include receiving seismic data due to a plurality of seismic sources and applying a first operator to the seismic data in an ith domain to generate a first estimate of seismic data due to an ith seismic source. The ith domain may correspond to the ith seismic source of the plurality of seismic sources. The method may then include applying a second operator to the first estimate of seismic data due to the ith seismic source in one or more domains other than the Ith domain to generate residual seismic data due to one or more seismic sources other than the Ith seismic source. After applying the a second operator to the first estimate of seismic data due to the ith seismic source, the method may determine a second estimate of seismic data due to the ith seismic source based on the first estimate and the residual seismic data due to the seismic sources other than the Ith seismic source. The method may then repeat some of the steps described above (i.e., applying a first operator to the seismic data, applying a second operator to the first estimate of seismic data and determining a second estimate of seismic data due to the Ith seismic source for each seismic source). The method may then process the second estimate of seismic data due to each seismic source to determine the presence of hydrocarbon deposits in a subterranean area of the earth.
