Automated and real-time field PSTM: how to QC more efficiently 10 billion traces today and more tomorrow

An automated and real-time field PSTM system, called TeraMig, was applied during the acquisition of a land 3D WAZ survey for PDO. The system was used to migrate one million vibrated points (around 10 billion traces) and was able to generate a real-time field PSTM cube as the seismic shots were recorded. The intermediate PSTM cubes were available in the field for instantaneous quality control. Daily reports including seismic data were sent to the end users (i.e., client, processing center). Immediately after the last recorded VP, the complete PSTM volume was ready to be delivered.
