Instantaneous Phase fundamentals

Step 2/3

Before attribute computation - Reflected amplitudes

Step 3/3

With the Instantaneous Phase attribute

Step 1: Instantaneous Phase fundamentals.
The opposite panel gives an overview of the attribute characteristics.

Step 2: Before attribute computation - Reflected amplitudes.
The seismic section is the inline 2196 extracted from preSTM 3D seismic data (New Zealand, Parihaka Block). To deal with concrete matters, a section with depositional channels, prograding systems and onlapping occurrence has been chosen.

Step 3: With the Instantaneous Phase attribute.
Visibility of channels filling, prograding systems and onlaps is obviously enhanced with use of the Instantaneous Phase. Same inline is displayed.
