For our latest tutorial showing downhole VSP shear-wave processing and interpretation see

https://rayfract.com/tutorials/SH27_Test.pdf

We show gathering of SEG-2 channels recorded with 3-component AMBROGEO borehole geophone. Next we show import of the two aggregated SEG-2 receiver spreads into our version 5.03 Rayfract(R) software, frequency bandpass filtering, shear-wave first break picking and optimized interactive WET inversion.

Also we show plotting of our new shear-wave velocity vs. elevation graph calling into Golden Software Surfer.

Also we show editing of the plot axis titles in Surfer 11.


For another tutorial showing cross-hole shear-wave imaging of possible cavities below a concrete cap see

For our latest release notes see

We now allow plotting of downhole VSP velocity vs. elevation in a
new plot type in Surfer displaying up to four(4) VSP graphs in the
same Surfer plot.

See our updated tutorial

Also we now allow extracting a 1D vertical grid slice from any Surfer
.GRD grid e.g. from Poisson's ratio grid and plotting this in Surfer. See our updated tutorial

https://rayfract.com/tutorials/poisson_Surfer23.pdf

Also we now allow plotting multiple WET runs on one page with our
Standard version 5.03 as per
