Linear-radon-marchenko equation based internal multiple elimination

A non-transitory computer readable memory having computer-executable instructions stored thereon that, when executed by a processor, perform steps comprising:

• obtaining a seismic dataset, wherein the seismic dataset comprises a plurality of space-time gathers;
• determining a first truncation operator, wherein the first truncation operator mutes samples of each trace after a first predetermined intercept time in a transform domain;
• determining a second truncation operator, wherein the second truncation operator mutes samples of each trace before a second predetermined intercept time in the transform domain;
• and
• applying Marchenko internal multiple attenuation on the seismic dataset using the first and second truncation operators to determine an internal multiples-free seismic dataset.

A system, comprising:

• a seismic acquisition system configured to obtain a seismic dataset, wherein the seismic dataset comprises a plurality of space-time gathers;
• and
• a seismic processing system configured to:
• determine a first truncation operator, wherein the first truncation operator mutes samples of each trace after a first predetermined intercept time in a transform domain,
• determine a second truncation operator, wherein the second truncation operator mutes samples of each trace before a second predetermined intercept time in the transform domain, and
• apply Marchenko internal multiple attenuation to the seismic dataset using the first and second truncation operators to determine an internal multiples-free seismic dataset.
