Device and method for de-blending simultaneous shooting data with apex shifted radon transform

A computing device configured to de-blend seismic data associated with a subsurface of the earth, the computing device comprising:

• an interface configured to receive blended seismic data, wherein the blended seismic data includes traces having energies from two different shots that partially overlap;
• and
• a processor connected to the interface and configured to,
• apply an apex-shifted radon transform (ASRT) to the blended seismic data to transform it from a first domain to a second domain;
• apply a mute processing for removing all shots except a first shot in the second domain;
• apply a reverse ASRT to the given shot to obtain the first shot in the first domain;
• and
• generate an image of the subsurface based on the first shot in the first domain.

A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, implement a method for de-blending seismic data associated with a subsurface of the earth, the instructions comprising:

• receiving blended seismic data, wherein the blended seismic data includes traces having energies from two different shots that partially overlap;
• applying an apex-shifted radon transform (ASRT) to the blended seismic data to transform it from a first domain to a second domain;
• applying a mute processing for removing all shots except a first shot in the second domain;
• applying a reverse ASRT to the given shot to obtain the first shot in the first domain;
• and
• generating an image of the subsurface based on the first shot in the first domain.
