Data input
  • Import all records at one time
  • Efficiently assign geometry with layout chart
  • Support more than two vertical or deviated wells
  • Optionally load first-break picks together with seismic data for reprocessing
  • Support most third-party picks formats

Data processing
  • AGC, trace balance, and frequency filtering
  • Trigger delay correction
  • Undo or redo multiple steps in data processing
First-break picking
  • Manually pick first breaks with a trace magnifier
  • Automatically pick first breaks guided by velocity or waveform phase
  • Overlay shear waves of opposite polarity to assist picking
