Hello greetings! I am a beginner. I have a big su file with huge shot points, but I want to see a particular shot point in reduced velocity mode. I made a single file for those particular shot by using key=fldr. Now this file should have total 636 traces. I wrote a command suwind < indut su file key=tracl max=636 .......
However, in image I got values from2.84*10^5 to 2.85*10^5. Even when I want to see the image in reduced velocity mode, I need to set rv= >1000 whereas it should be rv=1 to 2. It seems like there are something wrong with units in the headers. Would anyone please help me with how can I fix these??? I am a new user; I will appreciate your help and time. Here I attached the header info. Thanks
FYI
636 traces:
tracl 1 636 (1-636)
tracr 284929 285564 (284929-285564)
fldr 2245
tracf 1 636 (1-636)
cdp 2245
offset 112464 120401 (112464-120401)
sx 376962
sy 5176643
gx 376962
gy 5176643
ns 2001
dt 4000
Dear all,
I have performed a time resample of some 500ns sampled 3D seismic data to
1ms intervals using the suresamp command as shown below, but was unable to
transcribe the 189-192 bytes of the Inline and the 192-196 bytes of the
crossline numbers.
segyread tape=Source3D.sgy|suresamp rf=0.5|segyhdrs|segywrite
tape=Output3D_1ms.sgy
I solved this problem by using the ASCII input/output function for trace
header on SeiSee, a free Windows software, to write out the header
information of the original file and then write it into the header of the
output file.
Is there a way to transcribe inline and crossline numbers using the SU
function?
