The velocity picks are velocities and times, are they not? Can you cut and paste one of your vnmo tnmo pairs into an email message? Obaid B. Fadhil A. Call the file stolt. Thanks for everything you do for me. I have made as you told me. In the terminal reply to me that the number of tmig and vmig must be equal. You have to make sure you have the right times and the velocities that correspond to them.
You means that i have to repicks in equal interval times, right? Understand that the migration by using the Stolt method depends on the number of velocity that is picked by the velocity analysis and save in vpick text file, put must be equal in Vnmo and Tnmo. The results of stack. Where is the migration operation in that?? You do not have to repick your velocities. What you need to do at this step is to make sure you are selecting from your nmo velocities file the tnmo and vnmo for the same cdp.
I make sure, put the picking is not right, in some cdps i picks more than 5 and other picks only 3. I think i have to repicks in equal intervals so sustolt can reades all the cdps well. Nmo-stack makes the data into an approximation of a zero-offset section. Migration uses a velocity model to convert the data into an image of a slice through the earth, focusing the data. Stolt migration does this as an f-k domain filter.
Please read my notes. No, you do NOT have to repick the data! There, are, of course, many variations of Linux, each which works equally well as a platform for SU. An older solution to the Windows versus Unix question is a system called Cygwin, which comes in 32 bit and 64 bit systems. For Microsoft Windows installations, you will need to also add an X-windows server. Finally, users may configure their windows as dual-boot platforms, enjoying either a completely linux or a completely Microsoft environment.
To install SU, you have to compile it on your computer. This means that you will need more than just the basic installation of your operating system. These include the C compiler usually some version of GCC and the X-windows graphics libraries, There are Fortran codes in SU, however, these are not essential to the package. There is also an X-windows environment called X-Quartz that is necessary for the X-windows graphics packages.
Nomenclature point. Select a convenient location on your system and make it writeable by yourself as a regular user. The commands that would be used to make this directory are.
Once here, enter the make install command. This will compile the standard Seismic Unix code. After the previous make file is finished, enter the make xtinstall command. This will compile the X-toolkit code. As a quick test, open the Cygwin command line, and enter the following command, modifying the paths to match your directory structure.
A copy of the SEG-Y file should have been created if the installation was successful. As a culturally diverse group of people with diverse research interests, our students and visitors have the freedom to choose research problems that suit them best.
Financial support from and collaboration with our sponsors makes this experience possible. The CWP is unparalleled in the breadth of its research program and has been instrumental in developing the foundation for such key seismic technologies as wave-equation-based imagery and tomography, inversion and processing for anisotropic media, and seismic interferometry.
The range of topics in the current CWP research portfolio includes:.
