  1. Parallel Geoscience Corporation SPW 3 Instantaneous Field QC

  2. Seismic Field QC • Instantaneous Field QC • Geometry and data QC

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

  4. Recording System (Sercel428/Aram/… NAS Data Storage SPW 3 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

  6. Real Time Data Input

  7. Real Time Data Input Read all files that get written to the RAID directory

  8. Real Time Data Input Read starting at the specified file.

  9. Real Time Attribute Analysis • Calculate and store attribute value in the seismic header • Amplitude (RMS, Average, Max, …) • Frequency (Dominant, Bandwidth, …) • Display attributes as map views

  10. Amplitude Attributes

  11. Frequency Attributes
