When it comes to land or marine acquisition (oil exploration, for instance), I can see from literature that quality control (QC) is performed during the survey to ensure that the seismic traces obtained are not faulty. However, I see contradicting values for the amount of data that is required for QC. In , it is mentioned that just around 10 bytes/minute are sufficient. Meanwhile in , it is mentioned that the data collected over the entire day is used for QC.
Can someone point me to a good source where I can understand this aspect better?
