Application of Seismic Attributes
Surface Attributes
​
1. Root Mean Square (RMS) Amplitude
Applying RMS amplitude attributes to our seismic data is done as below:
-
Go to “Seismic Interpretation” tab at the above and go to “Attributes” section and click the icon on the top right of the section which says “Surface Attributes”.
-
A window will pop out. Choose “Amplitude” and select “RMS amplitude”
-
Fill up the empty space beside the selected “Add to surface” option and also “Horizon” empty space at the Reference horizon part.
