Open Data/Open Source: Seismic Unix scripts to process a 2D land line

Brute Stack

The brute stack can be produced with the command:

scons brutestack.view

or from the tar file:

./brutestack.job

This command reads the cdp gather data and applies decon using supef. In order to define a decon design gate that depends on offset, I used sustatic to time shift the data to line up where I wanted the time gate to start. After decon (supef) the time shift is removed. Moveout using the brute velocity is applied followed by agc and a mute. This data is written to a file which is reread to create the brute stack shown in Figure 10. You can create a zoom of this plot using the command:

scons zoombrutestack.view

or

./zoombrutestack.job

You can make a movie of the gathers with moveout applied with the command:

scons movie_velfiltcdpsnmo.view

or

./movie_velfiltcdpsnmo.job
