Combining noise attenuation and wavefield reconstruction in seismic processing

A non-transitory, computer-readable medium storing instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations, the operations comprising:

• receiving seismic data comprising seismic traces collected from a land-based or marine seismic array;
• applying a noise mitigation process to the seismic data to generate a first stack volume;
• identifying, using a machine-learning algorithm, one or more traces of the seismic traces as having a relatively high residual noise, after applying the noise mitigation process, in comparison to other traces of the seismic traces;
• mitigating noise in the one or more identified traces;
• and
• performing a wavefield reconstruction to generate a second stack volume after mitigating the noise in the one or more traces after mitigating the noise in the one or more identified traces, to interpolate a portion of the wavefield corresponding to where the one or more identified traces were located and mitigated.

A computing system, comprising:

• one or more processors;
• and
• a memory system comprising one or more non-transitory, computer-readable media storing instructions that, when executed by at least one of the one or more processors, cause the computing system to perform operations, the operations comprising:
• receiving seismic data comprising seismic traces collected from a land-based or marine seismic array;
• applying a noise mitigation process to the seismic data to generate a first stack volume;
• identifying, using a machine-learning algorithm, one or more traces of the seismic traces as having a relatively high residual noise, after applying the noise mitigation process, in comparison to other traces of the seismic traces;
• mitigating noise in the one or more identified traces;
• performing a wavefield reconstruction to generate a second stack volume after mitigating the noise in the one or more traces after mitigating the noise in the one or more identified traces, to interpolate a portion of the wavefield corresponding to where the one or more identified traces were located and mitigated;
• and
• generating an image of a subterranean domain based on the seismic data after mitigating noise and performing the wavefield reconstruction.
