Our latest tutorial

https://rayfract.com/tutorials/Line14_WDVS.pdf

shows improved lateral resolution in basement using multiscale Conjugate-Gradient WET inversion and Wavelength-Dependent Velocity Smoothing (WDVS; Zelt and Chen 2016).

We use our default 1D-gradient starting model (Fig. 16) and alternatively our pseudo-2D DeltatV starting model (Fig. 10).

For our updated 2022 brochure see

We now optionally plot your reciprocal traveltime picks on your shot-sorted trace gathers. This allows quality control of first break picks and specified recording geometry.

Also we now allow display of shot-sorted traveltime curves at CMP positions instead of receiver positions.

For our updated tutorial showing multiscale WET inversion of NGU profile 1_1D see

https://rayfract.com/tutorials/1_1D.pdf

We now show using our fail-safe 1D-gradient starting model in Fig. 17 to Fig. 20.

Also view our new tutorial imaging landslide with the line crossing the landslide at

https://rayfract.com/tutorials/Gasch23.pdf

Also we updated our MDW2011 cross hole tutorial

https://rayfract.com/tutorials/MDW2011_23.pdf

to show improved resolution using WDVS smoothing and plotting of reciprocal traveltimes on shot gather traces for easy quality control.

For our updated 2024 .pdf manual see

We tested our latest version 4.06 in Windows 11 Pro 23H2 for ARM under Parallels Desktop 19.4.1 running on Apple 2023 Mac mini with Apple M2 ARM CPU and this works just fine together with Surfer 11 and CodeMeter USB dongle.

Correction to my previous post : should say

"We tested our latest version 4.06 in Windows 11 Pro ARM 23H2 under Parallels Desktop 19.3.1 running on Apple 2023 Mac mini with Apple M2 ARM CPU and this works just fine together with Surfer 11 and CodeMeter USB dongle."

We tested our Pro version 4.06 software using up to 8 CPU cores on Apple 2023 Mac mini with ARM CPU. 4.06 Standard can use up to 4 CPU cores for WET inversion only.

This does not work on Apple M2 ARM CPU when using the green WibuKey USB dongle.

For our latest tutorial showing import of SEG-2 shear-wave traces recorded for inverted source polarity at common source locations and picking of S-wave first breaks and Smooth invert see

https://rayfract.com/tutorials/SH_60m.pdf

For our new tutorial showing interpretation of strongly layered refraction over a faulted basement recorded for a long line with dense spacing of sources and receivers see

https://rayfract.com/tutorials/Line23.pdf

The imaged basement depth has been confirmed with 5 boreholes.

We now offer improved support for aggregating and importing DDS recorded SEG-2 channels for interpretation of Downhole VSP surveys. See tutorials
