Abstract
The present disclosure is related to methods, systems, and machine-readable media for interference attenuation of a residual portion of seismic data, such as may be recorded in a marine seismic survey. Recorded seismic data can be separated into a portion attributed to a source and a residual portion. Seismic interference attenuation can be performed on the residual portion.

A method, comprising:
- separating, by a machine, recorded seismic data indicative of a subterranean formation into a residual portion and a quantity of first portions that are coherent in a data domain, each first portion attributed to a respective one of a quantity of sources actuated as part of a marine survey designed to generate the seismic data;
- performing, by the machine, seismic interference attenuation on the residual portion to remove seismic interference from the residual portion;
- separating, by the machine, the seismic interference attenuated residual portion into an updated seismic interference attenuated residual portion and a respective second portion for each of the plurality of sources;
- and
- adding, by the machine, the quantity of first portions and the respective second portion for each of the quantity of sources to yield total separated data that is better indicative of the subterranean formation.
