Parallel Geoscience Corporation SPW 3 Instantaneous Field QC Parallel Geoscience Corporation started in 1988. Writing and selling affordable and easy to use seismic processing solutions. Ex-Amoco/BP background in exploration and processing especially experienced in 3D processing of first land 3D datasets. Experienced seismic processors and geophysical software developers

Seismic Field QC Instantaneous Field QC Geometry and data QC

What is Instantaneous Field QC ? Direct Network connection to recording system Input, QC, process and display in real time

Recording System (Sercel428/Aram/… NAS Data Storage  SPW 3 The Internet The Office

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

Attribute Mapping – 2D

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

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

Geometry Information If Geometry is in the seismic header of input, it is used Or input and apply SPS or UKOOA format data Interactive CMP binning for 3D
