SC3-RAV™ is a
comprehensive triaxial downhole seismic testing (DST) data reduction, analysis, and display
software package. The user is provided with an extensive set of mathematical
tools and patented (U.S. Patent #5,177,709 / Canadian Patent # 2,077,387)
algorithms in deriving DST (e.g., seismic cone (SC)) interval velocities and attenuation Q values
and quantifying vertical seismic profiling. In addition, SC3-RAV™
has functionality for reviewing frequency spectrums, comparing unfiltered and
digitally filtered traces and plotting interval velocity profiles. SC3-RAV™ also provides extensive chart editing, plotting, and exporting
functionality. SC3-RAV™ includes the following features:
- Configurable for either geophones or accelerometers.
- Extensive frequency spectrum analysis. Bandpass, high pass, low pass, and
notch digital filters.
- Polarization analysis.
- The ability to rotate the X, Y, and Z source wave responses onto a
single full waveform axis.
- The ability to rotate the X, Y, and Z responses onto the P-SV-SH raypath
coordinates.
- Seismic source wave incident angle estimation.
- Attenuation Analysis.
- Patented (i.e. U.S. Patent #5,177,709) P-Wave and S-wave velocity
estimation algorithm.
- Three independent velocity estimates for the X, Y, and Z components.
- Velocity estimate for the full waveform (i.e. ρ = √x2
+ y2 + z2).
- Batch job processing.
- Source wave arrival time estimation.
- Linear least squares regression interval velocity estimation.
- Reverse Polarity Technique.
- Forward Modeling Downhill Simplex Method in estimating interval
velocities.
- Display of seismic depth profile with trend line specification.
- Display of peak particle accelerations, velocities, and displacements.
- Calculation of interval Gmax values.
- The ability to carry out data interpolation to increase the time series
resolution.
- Post data stacking.
- Application of a signal decay function to minimize the effect of source
wave multiples.
- Display of calculated interval velocities.
