impact assessment of marine seismic surveys

摘要

patent summary: "impact assessment of marine seismic surveys". The present invention relates to methods and systems for near real time assessment of seismic data defects resulting from noise and seismic data acquisition system deviations during a marine survey are described. The methods and systems apply ground modeling to an underground formation model to generate synthetic seismic data based on noise and deviations in the seismic data acquisition system. Synthetic seismic data represents seismic data that would be collected by a marine survey conducted in an underground formation with the same structure as the earth model and includes noise defects and deviations in the seismic data acquisition system. Error estimation is applied to synthetic seismic data to assess defects at different stages of seismic data processing.
