Seismic Data Processing
Initial seismic processing was performed in the field on laptop computers. After the field crew demobilized more extensive processing was undertaken at ESRI's data processing facility.

(In-the-field Data Processing and Interpretation at Ceresco)
In the Field Data Processing Flow:
- Vibroseis correlation with synthetic sweep
-
True amplitude recovery - T**n power scaling
-
Spiking deconvolution
-
Scaling
-
FK filter - reject linear noise
-
Bandpass filter
-
Trace edits / Geometry
-
CDP sort
-
Velocity analysis (constant vel. stks)
-
NMO / Bandpass filter / AGC
-
Stretch mute - 30 percent
-
CDP stack w/root n scaling
-
Bandpass filter
-
Spectral whitening
-
Trace mix - 5 pt center weighted
-
AGC
-

Laboratory Data Processing Flow:
- Reformat field Data - SEG-D to internal format
-
Vibroseis correlation with synthetic sweep
(SEG-Y out)
-
Resample 0.5 ms to 1.0 ms
-
Trace edit / First break mute
-
True amplitude recovery - T**n power scaling
-
Geometry definition & assignment
-
Surface consistent amplitude scaling - source & receiver
-
Spiking deconvolution
-
Bandpass filter / Scaling
-
FK filter / Remove Scaling
-
CDP sort / Datum statics
-
Velocity analysis (constant vel. stks &
vel. spectra)
-
NMO / Bandpass filter / AGC
-
Stretch mute - 30 percent ---------> QC Stack
-
Surface consistent residual statics (max. stk power algorithm, 3 ms max static)
-
CDP trim statics, 1 ms maximum
-
CDP stack w/root n scaling
-
Spectral whitening
-
