Stacking velocities.
The stacking velocities are collected along the seismic lines and processed to show time versus velocity of the seismic reflectors. The data is used to generate a time velocity cube.
Before using then uncritical it is common to display and check the quality and extent to see how deep the cube should go.
The stacking velocities are located as in 06_Velocities as Survey03 and Survey04. There are more surveys in the dataset Tutorial data1 , but in this project we only need 3 and 4.
Exercise
Display stacking velocity.
- Do Zoom to Folder on Survey03.
- Open up folder Survey03; click on a stacking velocity dataset.
- Perform Map Data. Zoom in and study the display. The lines are mapped.
- Erase and perform Make bands of velocity an map. Zoom in and study the display. It is solid.
- Try different display commands on the various velocity data sets.
- Go to the Command panel. Use Display survey lines. Transfer this command to the Toolbar.
- Highlight folder Survey03 and apply Display survey lines from the Toolbar.
