Calculate a PseudoRelief Attribute (TECVA)
Generating a pseudorelief attribute (also known as TECVA) can assist with structural interpretation. It is often easier to correlate events on the enhanced reflectors, simplifying both fault and horizon interpretation.

 Go to the Process tab, add a Volume Maths (Simple) process (see Volume Maths Process (Simple)).

Volume Maths (Simple) settings:
 Volume 1 and Volume 2: Select the input stack.
 Use the multiply operation: x volume.
 The result will be a selectable volume.
Next, average the squared input stack from the previous process.
 In the Process tab, add a new Volume Smoothing process (see Volume Smoothing).
 Volume: select the created volume from the previous process.
 A new volume will be created.
Next, find the square root of the average (from the previous process).
 Add a Volume Maths process from the process tab (see Volume Maths).
 Click the blue "+" in the Volume Maths panel.

Volume Maths settings:
 Symbol: v1  select the volume created from the averaging steps.
 Formula: sqrt (v1)
 A new volume is created.
Phase rotate the pseudoRMS using a process.
 Add a Phase Rotation process (see Phase Rotation)

Phase Rotation settings:
 Volume: select the square root volume.
 Degrees: 90
 The new volume is created.
Finally, apply a Lowcut filter to remove lowfrequency vertical striping.
 In the Process tab, add a Bandpass Filter process (see Bandpass Filter process).

Bandpass Filter settings:
 Volume: choose the phaserotation volume
 File type: choose Highpass
 Windowing Model: select <<Whole Trace>>
 Stop: 2Hz
 Pass: 3Hz
 If the result looks "smeared", try increasing both the Stop and Pass values by 1 or 2 Hz.
