Abstract:
1. A method for processing seismic data, comprising: receiving seismic data acquired by at least one seismic sensor; applying a first operator to the received seismic data in a first domain to generate a first set of seismic data that corresponds to the received seismic data due to a first seismic source, wherein the first domain is an encoding domain for the first seismic source; applying a second operator to the first set of seismic data in a second domain to generate a second set of seismic data that corresponds to residual seismic data due to a second seismic source, wherein the second domain is an encoding domain for the second seismic source; applying the first operator to the received seismic data in the second domain to generate a third set of seismic data that corresponds to the received seismic data due to the second seismic source; applying the second operator to the third set of seismic data in the first domain to generate a fourth set of seismic data that corresponds to residual seismic data due to the first seismic source; determining an estimate of the received seismic data due to the first seismic source, wherein the estimate of the received seismic data due to the first seismic source is a sum of the first set and the fourth set and this sum is subtracted by the second set; and processing the estimate of the received seismic data due to the first seismic source to determine the presence of hydrocarbon deposits in a subterranean area of the earth.
