Geolog - Full Waveform Sonic Processing

Objectives:
This course is designed for users of Paradigm’s Geolog Full Waveform Sonic modules. It teaches the basics of using the array sonic processing tools by guiding the student through a typical workflow and procedures to:
  • Become familiar with array sonic waveforms
  • View/create an array sonic tool specification
  • Create other attributes for a given waveform
  • Unpack "packed waveforms" to the individual receiver logs
  • Perform data analysis and pre-processing of waveforms
  • Remove noise from waveforms using a depth average, time average and frequency filter
  • Remove gain and normalization amplitudes added to waveforms during data acquisition
  • Process dipole and monopole waveforms
  • Perform automatic and interactive picking of arrivals
  • Perform dispersion correction
  • Traveltime overlay
  • View the Semblance display for diagnostic analysis
Duration:
One day

Prerequisites:
This advanced class presumes that participants are experienced with basic Geolog® functionality and module processing.

Who Should Attend:
Geoscientists concerned with processing and interpretation of acoustic waveforms in Geolog.
