  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. SEG Y File Analysis

  7. SEG D File Analysis

  8. Real Time Data Input

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

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

  11. 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

  12. Amplitude Attributes

  13. Frequency Attributes

  14. Real Time Attribute Maps

  15. Real Time Attribute Maps

  16. Real Time Attribute Maps

  17. Real Time Attribute Maps

  18. Real Time Attribute Maps

  19. Attribute Mapping – 2D

  20. Average Source Amplitude Spectra

  21. Average Receiver Amplitude Spectra

  22. 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

  23. Geometry QC • Check of survey information • Check of offsets • Check Fold

  24. Geometry QC

  25. Geometry QC

  26. Geometry QC - Sources

  27. Geometry QC - Receivers

  28. Geometry QCSurvey Maps - 2D

  29. Geometry QC – Offset display

  30. Geometry QC – 2D

  31. Interactive CMP binning for 3D

  32. Geometry and Fold Display

  33. Seismic QC and EditingUsing Attributes • Edit and kill noisy records using Signal to Noise • Edit and kill noisy traces using amplitude and frequency attributes • Generate reports on data quality

  34. Signal to Noise Editing

  35. Exclusion Zones

  36. Automatic Trace Editing

  37. Real Time Display Trace KillsKilled Traces in Selected Highlight Color (Red)

  38. Trace Analysis ReportReal Time Audio Alarm

  39. Trace Analysis Report

  40. Real Time Seismic Display QC Display of every nth record on screen Optional output of every mth to JPG files and ftp to the office

  41. Real Time Seismic Display

  42. Real Time Seismic Display

  43. Real Time Display of Trace KillsKilled Traces in Red

  44. Send Reports and Images to Office • Set up connection for real time transfers • Close FTP window and connection stays active • Processing steps automatically use the FTP connection • Automatically send reports • Automatically send jpeg images of data

  45. Spectrum Display of a Trace

  46. Spectra Display

  47. Average Spectrum Display

  48. Remote Internet Access • Connect field QC PC to the internet • Run VNC server or TeamViewer on field PC • Run VNC client or TeamViewer client in office • Control and view field PC screen from the office

  49. Instantaneous Field QC Benefits • Quantitative measures of data quality

  50. Instantaneous Field QC Benefits • Quantitative measures of data quality • Automatically provide reports and images to office personnel and for client reports
