The Internet
The Office

5. Instantaneous Field QC and Processing
Connect directly to seismic recorder via Ethernet (ARAM, IO, Sercel 408 & 428)
Input a shot record as soon as it is written
Process the shot record through the processing sequence

20. Average Source Amplitude Spectra
Vibroseis data – average spectrum of each shot – notice very consistent data frequency range except at some higher frequencies of the sweep. Possible vib coupling problems at high frequency

21. Average Receiver Amplitude Spectra
Vibroseis data – average spectrum of each receiver – notice very consistent data frequency range except for a few receivers
