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
SEG Y File Analysis
SEG D File Analysis
Real Time Data Input
Real Time Data Input
Read all files
that get
written to the
RAID directory
Real Time Data Input
Read starting
at the
specified file.
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

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

Seismic QC and Editing
Using 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

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

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
