Advantages

Ability to record long wave train for Stonely wave analysis and the measurement of fracture aperature and permeabilty index.

The absolute value of the amplitude of the received waveform is measureable thus allowing for amplitude calibration.

Truly modular: other receiver and/or transmiter combinations possible up to 8 receivers and two transmitters.

Features:

  • Real-time color VDL plotting
  • User-defined waveform window (up to 100 mSec)
  • Full waveform analysis, including

    • first arrival repicking
    • waveform filtering
    • stand-off correction
    • mechanical property calculations
    • velocity analysis
    • trace coherence analysis
    • reflected tube-wave analysis
    • semblance processing
  • Individual waveform pair plotting


Sample color variable density log (VDL) with traces profiling transit time, p-wave amplitude, and tube-wave (permeability) amplitude.
