Importing wavelets and sets
Import wavelets in ASCII or SEGY format and import wavelet sets in .wav format. Wavelets can be saved and imported using a centralized library of wavelets you create. The wavelet library is accessed by all GeoSyn projects.
To avoid aliasing, GeoSyn doesn't extract frequency information higher than the Nyquist frequency of either the import data or the current model, whichever is lowest.
Separate procedures for importing wavelets and wavelet sets appear below.
To import wavelets:
1. From the Edit menu, select Wavelet properties ().
The Wavelet Properties
dialog box appears.
2. In the Import/Export pane, click Import to the right of the wavelet label to import a wavelet from disk. Alternately, import wavelets from a centralized wavelet library used by all GeoSyn models by clicking Retrieveto the right of the Library label to display the Wavelet Library dialog box, where you select the wavelet and then click Import wavelet; otherwise, continue with the steps below.
The Import time data dialog box appears.
3. In the Files of type drop-down list, select whether to import SEGY or ASCII data then browse to and select the file.
If you select a SEGY file, the Import
Wavelet Processing Flow
dialog box appears; otherwise, if you select ASCII, the Highlight
First Line
dialog box appears.
4. Select the first line to import then click Next.
The Highlight Last Line
dialog box appears.
5. Select the last line to import the click Next.
The Set Column Delimeters
dialog box appears.
6. Set the column
delimeters () by clicking in the display pane between
required columns. The green line can't bisect a data column. Double-click
column delimiters to delete.
7. Click the box
that appears below each delimeter to display the Select
from List dialog box and identify the data type.
8. Click Next.
The Finish
dialog box appears.
8. Click Back to change any previous selections or click Finish.
The Import Wavelet Processing Flow
dialog box appears.
9. Specify whether to taper the file on import, the name by which to identify the wavelet, the length of the operator, and then click OK.
To import wavelet sets
1. From the Edit menu, select Wavelet properties ()
OR
Right-click a wavelet and select Wavelet properties from the popup menu.
The Wavelet Properties: Wavelet
dialog box appears.
2. In the Import/Export pane, click Import to the right of the Wavelet Sets label. Alternately, import wavelets from a centralized wavelet library used by all GeoSyn models by clicking Retrieveto the right of the Library label to display the Wavelet Library dialog box, where you select the wavelet and then click Import wavelet; otherwise, continue with the below steps.
The Import a wavelet set dialog box appears.
3. Browse to and select the wavelet file in .wav format then click OK.
The Import Wavelet Groups from Wavelet Set dialog box appears.
4. Select the wavelet group(s) to import then click OK.
