Initial seismic processing was performed in the field on laptop computers. This processing produced stack sections with residual statics applied. After the field crew demobilized more extensive processing was undertaken at ESRI's data processing facility.

In the Field Data Processing Flow:

• Vibroseis correlation with aux channel

• True amplitude recovery - T**n power scaling

• Geometry definition / Trace edits

• AGC - 150 ms

• FK filter - reject linear noise

• Bandpass filter

• CDP sort

• Velocity analysis (constant vel. stks)

• NMO / Bandpass filter / AGC-150 ms

• Stretch mute - 30 percent

• Datum statics (1448 ft, 1000 ft/s)

• Residual statics (stk power optimization)

• CDP stack w/root n scaling

• Bandpass filter
