[OpendTect_Users] Free SEG-Y manipulation: SeiSee and SUNT

[Bert Bril]

Hi again,


I got some feedback from users on the SEG-Y manipulation. Most notably
from  Alexey Bogdanov (AGR/TRACS). It seems that a nice (free) candidate
is SeiSee from DMNG:

http://msk.dmng.ru/seisview/seisee.en.html

As Alexey states:

"With SeiSee one could do _ANYTHING_ with SEG-Y headers. Also it allow
minor SEG-Y data filtering, data format conversion and export of a
selected subset to new SEG-Y file... I used quite a lot of different
SEGY viewers: freeware, commercial, some internal SLB software during my
SLB days... But I do not remember any other application that could be
compared to SeiSee."

and:

"There is a fantastic option in that software package - export trace
headers to ASCII and import text headers from ASCII. As soon as you got
your ASCII file in table format you could use any third party software
to do math, filtering etc. or load it to OpenOffice Calc or Excel and do
visual editing. And of course in SeiSee you could do math operations on
header fields."

I heard about SeiSee before from others too, but never realized it could
actually manipulate the files (the name doesn't help).


About SUNT:

"Not everyone knows that there is a 'native' port of the SU (Seismic
Unix) utils to Windows and it is possible to download that port free of
charge from Visual SUNT (commercial graphical extension to SU):

And with help of SU (and in very rare cases Madagascar) it is possible
to do 'almost everything' with SEG-Y."


Lastly, there are tools mentioned on Wikipedia:
