Trace Attributes Steps

 

 

Instantaneous Amplitude

Usage:

The Instantaneous Amplitude step calculates instantaneous amplitude attributes for each trace and outputs each as a seismic trace in the output seismic file. Instantaneous amplitude is a measure of the reflectivity strength of events on a seismic section.

 

Input Links:

1) Seismic data in any sort order (mandatory).

 

Output Links:

1) Seismic attribute data in any sort order (mandatory).

Parameter Description:

 

Processing start time (ms) — Enter the start time (upper boundary) in milliseconds of the time gate where the calculation will start.

 

Processing end time (ms) — Enter the end time (lower boundary) in milliseconds of the time gate where the calculation will end.

 

Instantaneous Frequency

Usage:

The Instantaneous Frequency step calculates instantaneous frequency attribute for each trace and outputs each as a seismic trace in the output seismic file. This attribute is a measure of the frequency of events on a seismic section.

1) Seismic data in any sort order (mandatory).

 

Output Links:

1) Seismic attribute data in any sort order (mandatory).

Parameter Description:

 

Processing start time (ms) — Enter the start time (upper boundary) in milliseconds of the time gate where the calculation will start.

 

Processing end time (ms) — Enter the end time (lower boundary) in milliseconds of the time gate where the calculation will end.

 

Number of samples to average — Enter the number of seismic samples to be averaged during the calculation of the Instataneous Frequency step.

 

Instantaneous Phase

Usage:

The Instantaneous Phase step calculates instantaneous phase attribute for each trace and outputs each as a seismic trace in the output seismic file. This attribute is a measure of the continuity of events on a seismic section.
