Attributes In Seismic Data Displays

WinPICS calculates instantaneous amplitude, frequency, and phase, apparent polarity, and the cosine of instantaneous phase on the fly and displays them on your seismic window. Display one attribute in color, and the other with an overlaid wiggle display. By default, both the active and inactive attributes are the seismic amplitude.

You can display two attributes at a time: one active, and the second inactive. If you pick on an attribute display, the values of the active attribute will be written to your pick file. The attribute display is scaled for maximum dynamic range.

Available Attributes

The following attributes are available WinPICS :

Seismic amplitude
Instantaneous amplitude
Instantaneous phase
Cosine of Instantaneous phase
Instantaneous frequency - optional calculation parameters can be set
Apparent polarity

Displaying Attributes

Select a color display mode with an overlaid wiggle trace:

Overlaid Wiggle AreaO

Overlaid Wiggle o

Colored AreaC

From the Seismic Menu Bar select Display | Display Attribute .
Select which attribute you would like to be the active attribute. That is, which attribute you would like to be the source for your amplitude picks. Select the inactive attribute. This is, the attribute you would like to be displayed but not picked as an amplitude. Choose to display each attribute as a wiggle or in color.

You can set the upper frequency limit and the smoothing gate for instantaneous frequency by clicking on <Options> in the attribute window. Enter an upper limit between 0 and 250 Hz and a smoothing gate between 0 and 100 ms.
You can use the Copy And Paste parameters to transfer your attribute display parameters to new seismic window.
The status line in the lower left-hand corner of the main window reports the values for the active attribute as you pass your cursor over the seismic window.
