Hello
I am looking for a software for Zero Offset Processing, but all softwares
are required money. I've found this mailing list. So, I can try Seismic
Unix for this. However, I guess it is tough doing Zero Offset VSP
processing on Seismic Unix.
Still, I want to ask. Does anyone have VSP fundamental processing scripts?
If so, I would be appreciated.
Thank you

Erdi,
I cannot help you with scripts, but the SEG has published a not-too-expensive booklet
titled “VSP Interpretive processing, Theory and Practice” by Hinds et al. It does not
contain SU scripts, but it gives stepwise processing sequences which can be converted into
SU script by someone familiar with SU
Good luck
Gerhard

Hi,
SU has basically all the necessary stuff to process zero offset VSP (at
least basic processing)
- header and trace editing if necessary
- first break picking (manual and/or automatic) to get time to depth
relation
- usual seismic signal processing tools
- downgoing/upgoing wave separation by FK, median or SVD filtering (and
static correction to align events)
- waveshaping for multiple elimination
- muting/stacking to compute corridor stack
and , of course the necessary functions to plot everything !
As you may know, it's difficult (tedious) to write scripts for every
kind of data and personal scripts are not always well
documented/commented (I think that this can be called an understatement !)
My advice would be that you try to write your own scripts and ask the
list to get help when you encounter difficulties.
Enjoy SU

Dear experts,
I agree that SU has all the capabilities to process VSP datasets. A while
ago, I made an attempt to write documentation on how to process simple Zero
Offset VSP using Seismic Unix. (https://github.com/fahdi104/latihanvspsu).
This documentation still needs a lot of work, but it's easy to demonstrate
the use of sufbpick, sumedian, supef, and sustack, to process Zero Offset
VSP.
The other free/academic software that can be used for VSP processing is
DSISoft. And since CREWES (
https://www.crewes.org/ResearchLinks/FreeSoftware/) research groups have
been focusing a lot on VSP, their free matlab toolbox has a lot of tools
for VSP processing.
Rgds,
fahdi

Dear Fahdi
I tried to access this one www.gm2001.net/latihanvspsu/ but it's linked to a Chinese
site .
If you have the zipped version it would be much easier
Thanks much

New subject: SU trace header Wiki page problem
Hi Folks -
A minor thing I just noticed ... On the SU trace header wiki page ...

The Description for key "nhs" (bytes 33-34) is missing (blank). This might be
due to a small error in the source code, a missing "|" (pipe, as we say in
Linux) at the end of the Description.
I can log into the site but I don't seem to have edit permission. Someone please lend
a hand.
