1. One or more tangible non-transitory computer-readable storage media storing computer-executable instructions for performing a computer process on a computing system, the computer process comprising:
obtaining seismic data, the seismic data acquired by a plurality of seismic receivers deployed in a survey area based on seismic energy emitted by a plurality of seismic sources, the plurality of seismic sources being deployed in the survey area according to a survey, the seismic data including noise from the survey;
obtaining an optimization model having an operator containing timing information describing overlap of the plurality of seismic sources in the survey; and
generating reconstructed records for the survey through a sparse inversion on the optimization model and an attenuation of energy, the sparse inversion and the attenuation of energy removing at least a portion of the noise.
