A typical 100,000-channel uncorrelated seismic shot record is approximately 1.5 GB in size. Coupled with the latest simultaneous source techniques, daily data volumes in excess of 15 TB can be expected. Only a truly integrated approach can meet the challenges of managing, checking and processing such volumes.
Quality control happens in real time in the recording truck. Raw sensor measurements (RSM) and equipment status information continually streamed from the ground electronics enables continuous monitoring of the spread equipment condition. Real-time quality control uses the power of the OMEGA2 seismic data processing software to focus on trace- and gather-based QC. QC result flags are written to headers for action in later processing. The QC'd RSM are moved onto custom-designed high-capacity removable hard disks for transfer to the base camp in-field data processing center. Once in camp, the RSM undergo fit-for-purpose digital group forming (DGF) for noise removal and data reduction, prior to full processing to generate a field cube.
