Seismic Processing Classification processingType extProcessingType refinedProcessingType refinedExtProcessingType POSC 1.0 migrated The data is characterized as having been migrated into a single trace per bin. static corrected The data is characterized by having been corrected for static shifts. stacked The data is characterized by having all traces at a given CDP bin being appropriately corrected, and summed together. DMO corrected The data is characterized as having the traces corrected for moveout variation using DMO (dip moveout) technology, but not yet summed together. NMO corrected The data is characterized as having the traces corrected for moveout variation using NMO (normal moveout) technology, but not yet summed together.
