Band-pass Filter

Band-pass filtering can be applied to an individual seismic line or to a seismic line within a fence display for line tie purposes.

Use the Band-pass Filter Function

1. Right-click on the seismic line you wish to band-pass filter and select Tie with Diagnostics from the shortcut menu (or press <t> on your keyboard). If you opened the Tie with Diagnostics window from a fence display, you can use the cross-correlation analysis or spectral analysis to analyze your line tie.
2. Select one of the following filters;
   • Ormsby Wavelet
   • Ricker Wavelet
   • Butterworth Wavelet
   • Klauder Wavelet
3. After modifying the Filter Parameters, click <Apply> to view changes.
4. Click <OK> to exit and save the band-pass filtered corrections on the fly. Alternatively, click <Cancel> to exit without applying corrections.

• Band-pass filtering is processed and displayed on the fly by default. You also have the option to process a new version of the data. Original versions are opened by right clicking on the seismic line and selecting SEG-Y Version. See Version Names for SEG-Y Data for the naming convention of new versions.
• WinPICS maintains only one pick file for each line. You may need to re-pick your data after applying band-pass filtering. Picking on the new version will replace picks made on previous versions. You can define more than one horizon name for each horizon and pick each on a different version if you like.
