is the trace envelope while, denotes convolution and is the differential operator. Characteristics of the second derivative of the envelope include:

  • Shows all reflecting interfaces visible within seismic band-width.
  • Shows sharpness of events.
  • Indicates sharp changes of lithology.
  • Large changes of the depositional environment, even when the corresponding envelope amplitude may be low.
  • Very good presentation of the image of the subsurface within the seismic band-width.
