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

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

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
D.

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
