Hi, I need to calculate AVO attributes (intercept and gradient) from the common shot gather data. I created the 2D synthetic shot gathers using Seismic Unix with an assumption of perfectly flat layers in the model domain. Does anyone know or have any shell scripts that could be used to create CDP ga...

Hi, I posted my request earlier to get some help regarding AVO attribute calculation from the common shot gather data. I am creating this post again to get further help. I created the 2D synthetic shot gathers using Seismic Unix with an assumption of perfectly flat layers in the model domain. Does a...

Hi Michael, I appreciate your suggestion. Yes, I have used Seismic Unix to create 2D acoustic synthetic seismic data. Do you know or have any shell script that could be used to extract AVO attributes from these Seismic Unix generated synthetic seismic data. I would really appreciate your help. Best,...

Hi,    I need suggestions for AVO analysis. I have 2D synthetic seismic data in the form of common shot gather, and I want to estimate the AVO intercept (zero offset reflectivity) and AVO gradient. The synthetic seismic data is available for 200 years of monitoring at a 10 year increment, and I aim ...

Hi Mitchell,
I really appreciate your help.

Hi Abhash, These output files as binary files. Use b2a <hsfile.out and you will have a text file with two columns of data in an ascii file. You can also view the header ranges and the output synthetic seismic data using surange and suximage as usual. Also check out the example here https://github.c...

Hi, I am using Seismic Unix to perform 2D acoustic seismic modeling. In particular, I used "sufdmod2" functionality of Seismic Unix to create synthetic seismic dataset (shot gathers) and saved output files by using $hsfiles flag. I put ".out" extension for each of the output file...
